Speaker: Rita P. Ribeiro, Assistant Professor @ University of Porto

Title: Online Anomaly Explanations - case study of Metro do Porto

Abstract: Data-driven Predictive Maintenance is becoming increasingly important in many industries. This approach involves using machine learning algorithms on historical and real-time data from various system parts to detect anomalies and possible defects in equipment before they lead to failure. Black-box models based on deep-learning techniques are popular due to their high predictive accuracy. However, as these systems become more complex with many interacting components, it's crucial to ensure the trustworthiness of these models through explainability.

In this talk, we will present a two-layer data-driven predictive maintenance framework. The first layer uses autoencoders for fault detection, while the second employs an online rule-learning algorithm to explain anomalies. We will showcase this framework in a case study on a train from Metro do Porto, Portugal, demonstrating how it fulfils the requirements for early detection of failures and provides explanations for those anomalies.

Biogram: Rita P. Ribeiro is an Assistant Professor at the Department of Computer Science at the Faculty of Sciences of the University of Porto (FCUP) and a Senior Researcher at the Laboratory of Artificial Intelligence and Decision Support (LIAAD) at the Institute of Systems Engineering and Computing, Technology and Science (INESCTEC).

Speaker: Jakub Gomułka, Professor @ Faculty of Humanities of AGH University of Krakow,

Title: The Wittgenstein Ontology Project

Abstract: The present paper concerns the Wittgenstein ontology project: an attempt to create a Semantic Web representation of Ludwig Wittgenstein’s philosophy. The project has been in development since 2006, and its current state enables users to search for information about Wittgenstein-related documents and the documents themselves. However, the developers have much more ambitious goals: they attempt to provide a philosophical subject matter knowledge base that would comprise the claims and concepts formulated by the philosopher. The current knowledge representation technology is not well-suited for this task, and a non-standard approach is required. The creators of the Wittgenstein ontology project are aware of this fact; recently, they have been discussing conceptual devices adjusting the technology to their needs.

Biogram: Jakub Gomułka, PhD (hab), Prof. AGH at the Faculty of Humanities of AGH University of Krakow, is interested in the philosophy of Ludwig Wittgenstein and Stanisław Lem, as well as the application of AI technology in the humanities. His recent publication include the following papers: “Tractatus 6 Reconsidered: An Algorithmic Alternative to Wittgenstein’s Trade-Off” (2023, co-authored with Adam Roman), “Towards a Computational Ontology for the Philosophy of Wittgenstein: Representing Aspects of the Tractarian Philosophy of Mathematics” (2023), and “Artificial Intelligence applied to philosophy : a contribution to the Wittgenstein Ontology project” (2023).

Speaker: Barłomiej Nawara, PhD Candidate @ Jagiellonian University

Title: Evolution of Science in the AI and Big Data Era: Modeling, Replication, Expertise

Abstract: This seminar talk presents an integrative analysis of the transformative effects of Artificial Intelligence (AI) and Big Data (BD) on scientific methodologies, with a particular focus on the emergence of Software-Ladent (SL) science. Central to this investigation is the philosophical exploration of Big Data Science, drawing from seminal works by Boyd & Crawford, Kitchin and others, which position Big Data Science at the intersection of data-driven and software-intensive scientific approaches. This convergence is encapsulated in the concept of Software-Ladent (SL) science, where software is integral to scientific inquiry, underpinning automated inferences and algorithm-driven analyses.

The presentation delves into the methodological changes recently brought about by Large Language Models (LLMs), marking a shift from classical methods to a software-intensive approach. This shift is contextualized within the broader philosophical debate of data-centric versus theory-centric approaches and the iterative nature of discovery in the Big Data era. The transformative impact of AI and Big Data on scientific methodologies, raised the new challenges, particularly in the replicability and the explainability of scientific results, suggesting the need for reevaluation of research methodologies in light of SL science.

Biogram: Bartłomiej Nawara. Data Scientist, philosopher and Phd candidate at Jagiellonian University. Area of interest: Information and knowledge theories, philosophy of data science and NLP.

Speaker: Jeremi Ochab, Assistant Professor @ Jagiellonian University

Title: Fractal and multifractal organisation of neuroimaging signals in cognitive tasks and in disease

Abstract: In this talk I will present A) a detrended fluctuation analysis of functional magnetic resonance imaging (fMRI) data from a working memory experiment, B) a machine-learning approach to the same data, and C) a multifractal analysis of the electroencephalography (EEG) data obtained from patients with multiple sclerosis (MS). fMRI and EEG signals are notoriously challenging to analyse due to their very low temporal and spatial resolution, respectively, and a non-trivial auto-correlation and cross-correlation structure. In A), we applied fractal analysis to investigate how a person is memorising and retrieving information in four types of experimental tasks: two visual-verbal (based on lists of semantically or phonetically associated words) and two non-verbal (pictures of similar objects). The regional brain activity was quantified with the Hurst exponent and Detrended Cross-Correlation Analysis (DCCA). Among others, we uncover regionally coordinated changes by analysing eigensystems of detrended correlation matrices. In B), we applied several linear and non-linear classification methods (among others QDA, Random Forests, hyperparameter tuned Light Gradient Boosting Machine, and ResNets) to the abovementioned fMRI signals in several multiclass settings. Our tests showed that information crucial for producing good classification results (aka explanations) is localised in a small number of ROIs. I will also show how important it is for such explanations to scrutinise neural time series for cross-correlations. In C), we compared the complexity of the EEG time series, paying particular attention to analysing the correlations between the degree of multifractality, disease duration, and level of disease progression quantified by the Expanded Disability Status Scale (EDSS). We used Multifractal Detrended Fluctuation Analysis, a generalisation of the DFA which is a robust tool for multilevel characterisation of time series. Based on the generalised Hurst exponents, we obtained the multifractal spectrum. To quantify the coupling between the brain regions we again used the DCCA.

Speaker: Andrzej Siódmok, Professor @ Jagiellonian University

Title: Towards a deep learning model for hadronization - an example of the application of the ML generative models in high-energy physics.

Abstract: The Large Hadron Collider (LHC) is the highest-energy particle collider and the largest and most complex machine ever built by mankind. At the LHC, particles (protons) are accelerated to speeds close to the speed of light, and when they reach sufficiently high energies, the protons collide with each other. These collisions, of which there are a billion per second, produce hundreds or even thousands of particles that need to be analysed. That is why LHC produces very large amounts of high-quality data that can be used for applications of machine learning methods and this is why over past years, modern machine learning has been quietly revolutionizing particle physics.

One of the greatest challenges for obtaining accurate theoretical predictions that can be used for discovery in LHC comes from the fact that there is a huge gap between a one-line formula of a fundamental theory, like the equation of Standard Model (SM), and the experimental reality that it implies. General Purpose Monte Carlo (GPMC) event generators are computer programs (often exceeding 500,000 lines of code) which are constructed to bridge that gap. One can think of a GPMC as a “Virtual Collider” that produces simulated collisions similar those that are produced in the actual LHC experiments, and therefore its results can be directly compared to the experimental data. One of the least understood components of these virtual colliders is the so-called hadronization. Hadronization is a complex quantum process whereby quarks and gluons become hadrons. The widely used models of hadronization in GPMC are based on physically inspired phenomenological models with many free parameters. We propose an alternative approach whereby neural networks are used instead. Deep generative models are highly flexible, differentiable, and compatible with graphical processing units. We also make the first step towards a data-driven machine learning-based hadronization model.

Talk is based on two papers:

Title: Synthetic Data Generator for Predictive Maintenance in Steel Manufacturing

Abstract: In the era of Industry 4.0, where automation, data, and connectivity converge to revolutionize manufacturing and industrial processes, the need to identify and address irregularities is more critical than ever. Anomaly detection, a fundamental component of data-driven decision-making in this context, is the key to ensuring smooth operations, maintaining product quality, and preventing costly disruptions. Developing machine learning-based anomaly detection systems presents significant challenges. Trustworthy labels are often scarce, making model training difficult, and noisy data can lead to false alarms. Moreover, the low number of actual faults, particularly in infrequent anomaly scenarios, complicates the model's ability to detect rare anomalies accurately. These factors often hinders the development of ML models for PdM, as they undermine the evaluation process. To address this challenges, we present a synthetic data generator, which is based on physics-based model from a steel manufacturing process. In the dataset we generate the different types of anomalies and deteriorations, which might occur in the real-world process. The data generator can be used in areas such as Anomaly Detection, Remaining Useful Life prediction and Explainable AI.

Speaker: Michał Kuk, PhD Candidate @ AGH University of Science and Technology

Title: Time-Series Complexity into Understandable Prototypes: A Generic Approach to Machine Learning Explanations in Industrial Processes

Abstract: Machine Learning (ML) algorithms have become integral tools in modern industrial processes due to their ability to learn complex patterns, make predictions, and facilitate decision making. However, a crucial challenge persists - their lack of explainability. This often leads to difficulties in conveying their working principles in an understandable manner, particularly when applied to time-series data.To enhance the explainability of ML models in industrial contexts, explanations should be formulated more generically, taking into account periods characterized by particular ranges of data, rather than focusing solely on specific instances. We propose a novel approach to ML model explanation that creates prototypical sets - defined as representative data segments with characteristic behaviors. This method allows simplicity and a better understanding of the complex time-series data.

Speaker: Przemysław Stanisz, PhD, ArcelorMittal Poland

Title: Modeling of advanced nuclear systems

Abstract: The reliability and safety of the nuclear systems are estimated in a series of numerical simulations performed using various numerical tools. The tools should provide a high confidence level of confidence in the estimated system description. One of the approaches dedicated to nuclear reactor full-core analyses that meet these requirements is the Monte Carlo methods for neutron transport. The Monte Carlo neutron transport codes are widely used in various reactor physics applications, traditionally related to criticality safety analyses, radiation shielding problems, detector modeling and validation of deterministic transport codes. The main advantage of the method is the ability to model geometry and interaction physics without large approximations. The importance of Monte Carlo calculations is increasing, along with the development of computer capacities and parallel computing, making it an efficient used solver for physical problems. During the presentation I will try to give an intuition how Monte Carlo neutron transport codes can assess the neutron distribution of the reactor core. In the second part I will present how the obtained distribution can be used for the evolution of the nuclide composition with time, and what are the main drawbacks for this approach. Finally, I will present the concept of the trajectory period folding method, which I developed during my PhD. studies.

Speaker: Artur Miroszewski, Postdoctoral researcher @ Jagiellonian University

Title: Use of quantum computation in satellite data analysis

Abstract: In the presentation, I consider extending classical Support Vector Machines (SVMs) with quantum kernels and applying them to satellite data analysis. The basic idea behind quantum computation and particular use cases for application of quantum computers in the field of remote sensing will be introduced. The design and implementation of hybrid SVMs with quantum kernels is then discussed. Here, the pixels are mapped to the Hilbert space using parameterized quantum feature maps associated with quantum kernels. The parameters are optimized to maximize the kernel target alignment. The quantum kernels are selected such that they enable analysis of numerous relevant properties while being able to simulate them with classical computers on a real-life large-scale dataset. Specifically, I approach the problem of cloud detection in the multispectral satellite imagery, which is one of the pivotal steps in both on-the-ground and on-board satellite image analysis processing chains. The experiments performed over the benchmark Landsat-8 multispectral dataset reveal that the simulated hybrid SVM successfully classifies satellite images with accuracy comparable to the classical SVM with the RBF kernel for large datasets. Interestingly, the high accuracy was also observed for the simple quantum kernels, lacking quantum entanglement.

Title: Current Trends in Learning from Data Streams

Abstract: Learning from data streams is a hot topic in machine learning and data mining. In this talk, we present two different problems and discuss streaming techniques to solve them. In the first problem, we propose an architecture to explain black-box models for predictive maintenance. The explanations are oriented toward equipment anomalies in Metro do Porto trains. For the second problem, we present one of the first algorithms for online hyper-parameter tuning for streaming data. The Self hyper-Parameter Tunning (SPT) algorithm is an optimization algorithm for online hyper-parameter tuning from non-stationary data streams. SPT works as a wrapper over any streaming algorithm and can be used for classification, regression, and recommendation.

Title: Machine Learning-based industrial process control with explainable decision support

Abstract: Real industrial processes carry significant consequences with every decision made. The idea is to develop a decision support system that can be easily understood by operators to make optimal process control decisions in real-time. The proposed method aims to define proactive control and as a result, prevent potential issues before they occur by using simulations and virtual sensors. The algorithm uses machine learning techniques to combine physical and virtual sensor data obtained from a simulation model to identify the process stage. Appropriate control actions are determined based on a control scheme directly dependent on this stage. In the proposed approach the control scheme is created by an expert human, based on the best industrial practices, making the whole process fully interpretable. To obtain optimal process control the decision scheme proposed by a human expert is parametrized and optimized using an AI-based optimization method. Since the structure of this parameterized decision tree is suggested by the human expert, the decision-making process that is entirely automated remains straightforward to interpret. To make defined control more reliable for the operator, the Explainable Artificial Intelligence (XAI) techniques, which introduce transparency and intelligibility into the decision-making process of AI-based systems are applied. They help to replace the decisions suggested by AI-based system with human-understandable decision rules that exactly tell not only which action should be taken but also why relating the answer to the current process stage. The proposed methodology is illustrated on a case study of gas production from an underground reservoir, showing that it increases process reliability and improves performance by providing proactive process control.

Title: Using AI in healthcare – from outcome prediction through targeted interventions to EHR anonymisation

Abstract: In this talk we will present three aspects of AI research in healthcare pursued at Center for Applied Intelligent Systems Research at Halmstad university, Sweden.

Heart failure readmission prediction aims to lower the burden of unscheduled readmissions on healthcare, in terms of increased cost and a negative impact on quality of care. Being able to predict such a risk following a discharge is very helpful to initiate relevant interventions to optimize care and improve clinical and health outcomes. In recent study, a 30-day readmission prediction method was developed using a mixture of electronic health record (EHR) and data available at discharge. The study demonstrated a high enough accuracy for the tool to be of clinical relevance as a clinical decision support system (CDSS).

AI-based Targeted interventions at primary care level can significantly improve health quality. Primary care is often the first line of care that a person seeks for a medical concern. Several important decisions related to care management and planning are made, such as ordering diagnostic tests, writing referrals to specialised care etc., that influence the patient's overall health journey. AI is used to identify and understand factors responsible for all-cause hospitalisations, in particular support and learn from the different primary units based on their current practices and specific population characteristics.

GANs are becoming a popular tool for Electronic Health Records anonymisation. Data anonymisation has been used as a fundamental tool in various domains, e.g., healthcare, to alter personal data such that individuals can no longer be identified directly or indirectly in a way to enable broader sharing of data. Recently, the use of GANs for anonymising different data types such as EHRs has been showing particularly promising results.

Amira Soliman received her PhD from EECS school at KTH in March 2018. The PhD was an awarded fellowship by Marie Curie Initial Training Networks, European Union. During the PhD, she developed multiple algorithms that allow decentralised analytics to effectively work on top of fully decentralised topology when the data is fully distributed and participating nodes have access only to their local resources. She is currently working at Halmstad University as an assistant professor in information-driven healthcare. Her research experience spans distributed systems, data analysis, and machine learning with a focus on interlinked data analysis using graph theory for complex and large systems. The research is directed towards the exploration of new algorithms for supporting the design and implementation of robust and large-scale decentralised learning algorithms.

Awais Ashfaq is a research scientist at Region Halland and post-doc at Halmstad University, Sweden under the supervision of Markus Lingman and Slawomir Nowaczyk. He works on scientific machine learning, especially focusing on intelligible self-supervised learning algorithms for representing Electronic Health Records (EHRs) to build prediction models. Simply put, the objective is to transform patient health data at a given time from raw EHR format to meaningful information (embeddings or representations) that can further be understood clinically by humans and algorithmically by prediction models. Being able to predict or forecast risk of adverse outcomes or disease onsets on individual and societal level can trigger early interventions to avoid, or at least prepare, for medical complications and seasonal or regional epidemics.

Title: Interpretable Deep Learning with Prototypical Parts

Abstract: The broad application of deep learning in fields like medical diagnosis and autonomous driving enforces models to explain the rationale behind their decisions. That is why explainers and self-explainable models are developed to justify neural network predictions. Some of them are inspired by mechanisms used by humans to explain their decisions, like matching image parts with memorized prototypical features that an object can possess. Recently, a self-explainable model called Prototypical Part Network (ProtoPNet) was introduced, employing feature matching learning theory. It focuses on crucial image parts and compares them with reference patterns (prototypical parts) assigned to classes. In this presentation, we will present our papers concerning this topic published on the main track of three recent conferences (SIGKDD 2021, ECML PKDD 2022, ECCV 2022, and WACV 2023).

Title: Computational methods for Cryo-Electron Tomography: current challenges

Abstract: The cellular environment is characterized by the presence of many different molecular species, where macromolecular complexes, stable or transient, underlie critical cellular functions. Cryo-Electron Tomography (cryo-ET) is an extension of the technique that was Nobel awarded in Chemistry in 2017, cryo-Electron Microscopy (cryo-EM). With faithful sample preservation and direct imaging of fully hydrated biological material, cryo-ET enables an accurate three-dimensional (3D) visualization and analysis of the subcellular architecture at unprecedented resolution and in situ, i.e. under native conditions and preserving functional interactions.

Cryo-ET relies greatly on computing as cellular structures are highly heterogeneous and the interpretation of volumes (also known as cryo-tomograms) is severely hampered by several factors like noise, low contrast, and anisotropic distortions. Consequently, the development of specific computer methods is required to analyze data within cryo-tomograms. In addition, recent advances in hardware have brought cryo-electron tomography to a new era by incrementing dramatically data quantity and quality, but at the same time has converted data analysis in a major bottleneck of this technique.

In this talk we are going to introduce the challenges in the development of image analysis methods to automatically interpret the reconstructed cryo-tomograms and derive quantitative information about cellular processes at macromolecular level.

Title: Improving batch job scheduling with AI

Abstract: Batch jobs and scripts are the primary way of describing and submitting computing tasks in virtually all major high-performance computing environments. Scheduling of batch jobs is a non-trivial task that is crucial for the effective use of computing resources as well as for user experience. Existing schedulers usually use heuristics based on task description and users’ statistics to assign priority to each job. In recent years, AI-based solutions aimed to improve overall batch scheduling efficiency have been proposed. By leveraging reinforcement learning methods and including additional runtime factors into the scheduling process, they can in real-time adapt to changing cluster state and, in consequence, make better scheduling decisions. In this talk, I will present the current state of the art on the topic and propose some ideas on how to improve existing solutions.

Title: Machine learning applications in Biological Anthropology

Abstract: Artificial intelligence is revolutionizing all fields of human knowledge, from social sciences to medical and experimental disciplines. Machine learning methodologies are shedding light on different aspects of the evolutionary history and the biological diversity of humankind, based on the availability of big data in different areas of Biological Anthropology, from anthropometric measurements and skeletal virtual imaging to genomic information of past and extant human populations. Here, I will review several applications of ML in Paleoanthropology, Forensic Anthropology and Human Population Genetics, for instance, in sex and ancestry classification of skeletal remains and for testing new hypothesis regarding introgression events between hominin species and our ancestors. Finally, I will present some details on an ongoing project, in which we aim to integrate ML approaches in a massive genomic analysis (exome sequencing) of β-thalassemic patients from southern Spain. We want to model the relationship between genetic variants (genotype) and clinical outcomes (phenotype) for (i) identifying deleterious genetic variants, (ii) studying the possible association among these mutations and the clinical severity of the disease and (iii) assessing the role of population ancestry and different evolutionary phenomena (gene flow, natural selection) in the human deleterious genomic composition.

Title: Hypernetwork approach to few-shot learning

Abstract: The aim of Few-Shot learning methods is to train models which can easily adapt to previously unseen tasks, based on small amounts of data. One of the most popular and elegant Few-Shot learning approaches is Model-Agnostic Meta-Learning (MAML). The main idea behind this method is to learn the general weights of the meta-model, which are further adapted to specific problems in a small number of gradient steps. However, the model’s main limitation lies in the fact that the update procedure is realized by gradient-based optimization. In consequence, MAML cannot always modify weights to the essential level in one or even a few gradient iterations. On the other hand, using many gradient steps results in a complex and time-consuming optimization procedure, which is hard to train in practice, and may lead to overfitting. In the seminar, I describe a novel generalization of MAML which produces larger updates by using hypernetworks.

Title: Digitalization of library handwriting resources and opportunities for Artificial Intelligence. The case of Autographa Sammlung in the Jagiellonian Library

Abstract: The Jagiellonian Library preserves a real treasure: the Collection of the former Prussian State Library. It includes the collection of Autographs, i.e., letters and documents written by the hand of famous people: writers, scientists, politicians, and even rulers. This collection is currently being prepared for digitisation and further research. However, the details of the descriptions/metadata generated during the digitisation process for manuscripts with existing tools are insufficient for the needs of researchers: philologists, librarians, historians. Therefore, we see a need for a new structure that works closely with existing processes and allows for the creation of rich metadata. During the seminar, we will provide an interesting history of the collections, their characteristics, and the main challenges faced by researchers working with manuscripts. Then, we will discuss the current infrastructure at the Jagiellonian Library and summarise the assumptions of the ongoing research project aimed at improving the research infrastructure using AI tools to maximize usefulness and provide the best mode of access to the collections. The seminar is also an invitation to AI researchers and research groups to collaborate on solving specific AI-related problems that arise in the project.

Title: Detection of multiple sclerosis from EEG signals using machine learning methods

Abstract: Multiple Sclerosis (MS) is a lifelong central nervous system disease. It is estimated that over 2.8 million people suffer from the MS. Although Multiple Sclerosis can lead to a range of symptoms including vision, sensation, and movement disabilities, early detection and treatment can improve patient’s quality of life and slow the progression of the symptoms. Unfortunately, there is no standardized testing for detecting early stage Multiple Sclerosis. Medical professionals use a variety of methods such as MRI scans or blood tests. These are not often reliable for early stage patients and can lead to the lack of proper treatment. In our work we review recent advancements, but also propose a fully automated and cost-effective method of MS detection based on the EEG signals

Title: Physics guided neural networks with application to financial modeling

Abstract: The success of current wave of machine learning methods that we observe in recent years can be partially attributed to deep neural networks. They represent data driven approach to modeling, so they can learn both known and unknown physics directly from data without prior knowledge of any physical laws, achieving good performance while maintaining computational efficiency. Despite advantages, there remain some challenges: they are typically data inefficient, sensitive to hyperparameters and may not generalize well. Physics-based modelling performs better in these aspects, but its main limitation is that it is limited to known and understood physics of described phenomena and it tend to be computationally inefficient. There are multiple ways to merge these two approaches and physics guided neural networks (PGNN) is one of them - it attempts to embed physics inside neural networks to benefit from advantages of both. In financial modeling, physics that are used to model dynamics of markets do or could benefit from such a hybrid approach. In this presentation I will talk about PGNN and their applications to modeling physics and phenomena utilized or originating in financial modeling.

Title: Hierarchical correlation reconstruction - between statistics and machine learning

Abstract: While machine learning techniques are very powerful, they have some weaknesses, like iterative optimization with many local minimums, large freedom of parameters, lack of interpretability and accuracy control. From the other side we have classical statistics based on moments not having these issues, but providing only a rough description. I will introduce and show on various applications (e.g. financial, medical) HCR family of methods combining their advantages: with MSE-optimal moment-like coefficients, but designed such that we can reconstruct (joint) probability distributions from them, also modeled in adaptive/evolving way, or predicted from other information

Title: Action Rules induction by Sequential Covering

Abstract: Decision rules have been widely used as a Knowledge Discovery tool during the past 30 years. This method excels especially when the clarity and comprehensibility of the model is required. Based on the notion and algorithms used for decision rules induction, a new category of rules called Action Rules has been created. An action rule is a special type of rule representing a dependency showing a possible way to move examples from the so-called source decision class to another one called a target decision class. Action rules were first described by Raś in year 2000, and since then many algorithms that discover action rules have been published. During the seminar I will describe the Action Rules and results of my thesis titled “Action rules Induction by Sequential Covering”. The thesis introduces new algorithms for Action Rules discovery based on the sequential covering paradigm, that is widely used in decision rule induction but was not yet employed in action rules discovery. Also a method to discover recommendations - specialized action rules, that are created for a specific example - and a testing workflow will be presented.

Biogram: Paweł Matyszok has been PhD candidate at the Silesian University of Technology since 2016. He holds B.SC and M.Sc in Computer Science.

Title: Learning classifiers from concept drifting and imbalanced data streams

Abstract: Stream classification is a challenging field in which machine learning algorithms are required to process data online, use minimal resources, and react to concept drifts, where the data distribution and target concepts (class) can change over time. In the first part of this talk, we discuss the use of the adaptive ensemble OAUE in such non-stationary streams. The task becomes even more demanding when the online classifier is required to cope with imbalanced data — situations when one of the target classes is represented by much less instances than other classes. Most existing work focuses on designing new algorithms for dealing with the global imbalance ratio in the data stream and does not consider other data complexities/factors. Despite often being present in real-world data, the interactions between concept drifts and local data difficulty factors have not been investigated in concept drifting data streams yet. In this part of the talk we put forward a new categorization of concept drifts for class imbalanced problems. Then, we summarize results of our two recent papers, where through comprehensive experiments with synthetic and real data streams, we examine the their influence on predictions of representative online classifiers and discuss the directions of future research.

Title: Human-in-the-loop approaches to XAI

Abstract: At the seminar, I will deliver a paper “Explain your clusters with words. The role of metadata in interactive clustering”, which I presented at the IJCAI-ECAI 2022 conference in Vienna. I will tell about the distinction between objective data and meta-data. Objective data is difficult to interpret but is closer to the physical aspects of the phenomena under study, e.g., it is sensor data. Metadata is data that describes other data, acquired subjectively, also often in a collaborative effort in the form of text, e.g., product descriptions on an eCommerce site. With metadata, it is possible to express what the ML model has learned in a human-legible language. I want to validate this approach as a way for a more personalised AI system. With this distinction about data in mind, I will bring forward for discussion a narrative-inspired approach for interactive clustering. The narrative approach to cooperation between humans and AI was taken from the concept of Data storytelling, a type of narrative in which ML models provide explanations about cause-and-effect relationships in the data. I applied this approach to the Human-In-The-Loop regime. In the end, I will briefly present what I am currently working on and what I anticipate as possible further research directions.

Title: Plot generation of computer narrative game with graph transformations

Abstract: The formalization of plot structures both in literature and game design is a big challenge for researchers and different formal models were proposed since the beginning of 20 century. The introduction of a formal model of adventure game plot description – based on graph representation and the graph generation procedure – and its application in computer-aided adventure game design is a goal of this presentation. Starting from Vladimir Propp theory, which inspired many researchers of literary structures in the field of information science, some theoretical concepts will be introduced: an n-layer graph, a sheaf graph (a graph structure created for modeling adventure games) and generic matching as a tool that determines the possible scope of modification and generic production as a direct representation of the player's actions. The entire game graph can be considered a forest of sheaf subgraphs embedded into a location layer subgraph through roots-locations. All paths from a given location branch to form a sheaf graph. This leads to the definition of a multisheaf graph. Typical modifications of the world resulting from game mechanics most often operate on one or more sheaves. Based on the theoretical graph model, the specification of the StoryGraph implementation standard was proposed, currently available as StoryGraph 1.2, which includes data validation, testing plot lines (game simulation), modeling the world, visualization of the world, production, and production hierarchy tree. The process of collaborative game design based on the presented model will be also described.

Title: Investigating and facilitating human geometric cognition through VR/AR technologies

Abstract: Learning the principles of geometry, similarly to numerical knowledge, plays a pivotal role in the acquisition of mathematical competencies that are useful in everyday life. What is more, many surveys (e.g., by OECD) suggest the prominent role of the level of abstract geometric competencies in developing individuals' well-being and societies at large. According to the mainstream cognitive science approach, these competencies are deeply hardwired in spatial navigation and object recognition, based upon, respectively, the core system of layout geometry (hippocampus and entorhinal cortex) and the core system of object geometry (lateral occipital complex). These core systems – being responsible for the processing of different geometric properties – are shared with non-human animals, and appear in the early stages of human ontogeny. However, they cannot fully explain a uniquely human form of Euclidean cognition and, even more so, individual differences in its level. Many empirical findings suggest that spatial language and artifacts use (maps, scale objects, etc.) mediate productive combinations of cognitive representations delivered by the core geometric systems. Again, the mainstream approach - grounded in various methodologies - emphasizes that facilitating these productive combinations in children leads to a deeper understanding of Euclidean geometry principles and the general development of abstract thinking. In this talk, I will focus on the contribution of virtual reality-based research to the understanding foundations of geometric cognition and the efficiency of VR-based cognitive trainings serving as STEM assistances. Considering the issue of ecological validity of experiments/interventions, I will also review (indeed scarce) contributions employing augmented reality-based methodologies. In both cases, I will outline perspectives of further studies and interventions.

Title: AI methods in computer modeling and recognition of emotions and humanization of computer systems

Abstract: Emotions are temporary shakes of mind with somatic reactions in meantime. They are crucial in human communication, and they let people understand each other with their state of mind. Non-verbal information is the main information shared with another person. Emotion recognition is a crucial element of Affective Computing related to the interdisciplinary field of science including devices and sensors, machine learning, signal processing and psychology. With this knowledge it is possible to create task sequences to automatically recognize emotion. Nowadays with fast growth of intelligent technologies and industry growth, we observe increased demand for technologies that are capable of satisfying clients and finding the right solution. Automatic emotion recognition has its appliance in robotics: in case of projecting intelligent robots that can help humans and communicate with him, in marketing: letting creation personalized advertise in according to emotional state of client, in education: to help improve efficiency of learning process, and knowledge transform, in games to adjust gameplay to player feeling. Current results of paperwork showing that accuracy isn’t satisfying if we assume that models should be universal. Major number of works do not include facts used in emotion recognition problems – personalization. First published works showing increased accuracy of models by using information about psychological features of users like personality to create personalized models. Result is to develop a collection of methods used to create mechanisms and personalization tools of emotional intelligent systems. Every work will be attached to the chosen use-case.

Title: Machine Learning in Drug Discovery: Applications and Techniques

Abstract: Machine Learning has been widely applied in drug discovery. The accurate prediction of molecular properties is a critical ingredient toward the societal and technological progress since it could speed up much research progress, such as drug designing and substance discovery. Also, it would cause more initiatives towards a personalized medicine. However, complete exploring “chemical universes” that potentially include infinite sets of compounds seems to be computationally intractable. In recent years, advances in the development of deep learning models have spawned a mass of promising methods to address the molecular property prediction task. During our presentation we will introduce the related background and share the experiences connected with the developed models that learn and predict molecular properties on unseen data.

Title: Semantic Data Mining Based Decision Support for Quality Assessment in Steel Industry

Abstract: Smart Manufacturing approaches are most often based on the use of machine learning models in tasks, where human cognitive abilities do not allow for efficient processing of available data. The talk is focused on quality management practices and our proposal of the decision support application based on sensor data collected during the steel products manufacturing. We have integrated domain knowledge, Six Sigma principles, ISO 9001:2015 recommendations, machine learning model, and XAI algorithms to create a semantic connection between data stream and human specialists. The original contribution of our research is the enhancement of current state of the art decision support methods grounded on statistical control. Instead of considering the relations between features based on distribution variability, an appropriate design of the experiment allowed us to identify defective products and compute the potential causes of the defect in the automated procedure

Title: Personalized NLP.

Abstract: Many natural language processing tasks, such as classifying offensive, toxic, or emotional texts, are inherently subjective in nature. This is a major challenge, especially with regard to the annotation process. Humans tend to perceive textual content in their own individual way. Most current annotation procedures aim to achieve a high level of agreement in order to generate a high quality reference source. Existing machine learning methods commonly rely on agreed output values that are the same for all annotators. However, annotation guidelines for subjective content can limit annotators' decision-making freedom. Motivated by moderate annotation agreement on offensive and emotional content datasets, we hypothesize that a personalized approach should be introduced for such subjective tasks. We propose new deep learning architectures that take into account not only the content but also the characteristics of the individual. We consider different approaches for learning the representation and processing of data about text readers. Experiments were conducted on several datasets: Wikipedia discussion texts labeled with attack, aggression, and toxicity, opinions annotated with ten numerical emotional categories and humour data. All of our models based on human biases and their representations significantly improve prediction quality in subjective tasks evaluated from an individual's perspective. Additionally, we have developed requirements for annotation, personalization, content processing and validation procedures to make our solutions human-centric.

Title: On open problems of theory of knowledge, based on Luciano Floridi’s theory of semantic information.

Abstract: Floridi's theory of semantic information is one of the most influential attempts to complement the Shannon / Weaver communication theory with a semantic aspect. In his later works, Floridi tries to expand it even more, in order to define General Theory of Information (GOT), an unsolved enlargement of Shannon / Weaver communication theory. However, it requires a clear distinction between data and information. Floridi notes that the level of abstraction at which data analysis ranks is different from the level of abstraction of the informational processes. This distinction is based on two categories of systems: Artificial Intelligent Behavior (AIB), i.e. AI systems, and Natural Intelligent Behavior (NIB). NIB systems are producing knowledge by processing information. While the AIB systems are only capable of experiencing data, knowledge produced by such systems must be somehow different from human produced knowledge. It is due to lack of so-called “anchoring in the world”, captured in the symbol grounding problem. There is currently no meaningful solution to this problem for AI systems. It's clear that the relationship between data, information and knowledge is difficult to describe using a simple hierarchy. Historically, this idea was implemented by the so-called DIKW pyramid, adding an extra degree of wisdom at the very top. Currently, despite the criticism of this approach, there is no in-depth analysis of the above-mentioned ingredients. Krajewski argue that the relation between data, information and knowledge should be expressed in something more than the usual equation signs between them. Open questions that arise in this matter relate, firstly, to defining knowledge produced by AI systems, and secondly, placing such knowledge in the context of theory of semantic information and GOT. Proposed solution must be consistent with SOTA. The presentation will cover Floridi’s semantic information theory, data-information distinction, and try to describe current status and open problems of theory of knowledge based on Floridi’s theory of semantic information.

Title: Explaining the Artificial Intelligence Act

Abstract: Abstract: Artificial Intelligence Act - currently proceeded by lead Committees of European Parliament - is presented as the regulation that should secure EU's position as the leader in promoting safe and innovative research of AI. It is a part of European Approach to excellence and trust in AI development, presented mainly in White Paper on Artificial Intelligence. The basic assumption of the strategy, of which the AIA is to be the most important basis is to provide space for innovative research and implementation of AI systems, whilst maintaining safety measures built around trust. However, adopted style of regulation focused on product safety seems not to be sufficient for reaching this goal. One of the downsides of AIA is a blurry regulation of explainability related subjects and their role in building trust to AI. Starting with lack of clear definition of notions such as 'transparency' and 'explicability', ending on very formal obligations imposed on producers, distributors and users of AI systems, it seems that AIA would serve rather as niuisance than help. In order to improve the regulation it is worth asking how to best balance values that it is meant to promote. Another venue of research is to identify what could be the best way to build trust to AI systems through explainability.

Title: Enhancing cluster analysis with explainable AI and multidimensional cluster prototypes

Abstract: Explainable Artificial Intelligence (XAI) aims at introducing transparency and intelligibility into the decision-making process of AI systems. Most often, its applications concentrate on supervised machine learning problems such as classification and regression. Nevertheless, in the case of unsupervised algorithms like clustering, XAI can bring satisfying results as well. In most cases, such an application is based on the transformation of unsupervised clustering task into supervised one. This is achieved by building a classifier on top of labels discovered in the clustering phase and applying XAI methods for the classifier. However, such an approach may cause the information about cluster shape and distribution to be lost. This, on the other hand, can influence the quality of the explanations. To cope with that we developed a novel approach for Cluster Analysis with Multidimensional Prototypes called ClAMP that aids experts in cluster analysis with human-readable rule-based explanations. The developed state-of-the-art explanation mechanism is based on cluster prototypes represented by multidimensional bounding boxes. This allows to represent an arbitrary shaped clusters and combine strengths of local explanations with the generality of the global one.

Title: Modern deep learning approaches for time series

Abstract: Due to their natural temporal ordering, time series data are present in almost every task that requires some sort of human cognitive process. Industries varying from health care, remote sensing and aerospace engineering all now produce time series datasets of previously unseen scale. However, in comparison to the fields of computer vision and natural language processing, the increasing use of time series has not been met with a complete adoption of deep learning-based approaches, and only during the last years have we seen some of the modern ideas from deep learning applied to time series. In this talk, we will go through some recent research in which trending topics such as self-supervised learning, neural-based visual analytics, and new neural architectures are studied for different use cases involving time series.

Title: Explainable anomaly detection in hot-rolling process

Abstract: Hot rolling is a complex manufacturing process, which require very accurate control systems and good maintenance strategies in order to produce high quality products. Faults at any stay of the process may lead to production of defected products, which is a significant economic loss for the manufacturer. One of the possibilities to improve production process is to discover anomalous observations as soon as they appear, because they may be a sign of greater production issues. In our studies we have used deep learning for detection of anomalies in a hot rolling process. More specifically we will focus on the autoencoder neural network architecture with certain extensions which improve the accuracy and reliability of the deep learning models.

In many cases, the analysis involves conformance checking between the discovered patterns and the expert knowledge that is in possession of a company. In this talk, I will show how explainable artificial intelligence methods (XAI) can be used to help experts analyse the results of clustering methods. I will also discuss challenges in using existing XAI algorithms for generating explanations for users without data-science experience.

Title: Visual Analytics for Aerospace and Healthcare Systems Design

Abstract: In this seminar, a systems engineering approach for the trade-off analysis of multiple criteria will be demonstrated with examples in aerospace and healthcare systems. Using a novel multidimensional data visualisation technique, the simultaneous analysis of the trade-offs between multiple stakeholder priorities and decision criteria is possible. Artificial intelligence, computational models, optimisation simulations and data analysis are utilised extensively, and multidimensional visualisation, as will be shown, can play a key role exploiting our fantastic pattern recognition ability in discovering relational information in such datasets and sequentially guiding complex design decisions in socio-technical systems.

Title: Recent developments of machine learning in experimental particle physics

Abstract: With modern physics experiments comes the need to process the growing amount of data. Collaborations behind the largest particle physics experiments at LHC estimate their detectors’ data throughput to notably exceed 1 TB/s during upcoming data-taking sessions. This implies that terabytes of multidimensional data will have to be continuously collected, filtered, and processed into the fully reconstructed tracks of each particle passing through the detector. Additionally, in order to be meaningful, every new measurement has to be compared with its Monte Carlo simulated equivalent. In this talk, I will show how machine learning, hardware-accelerated graph, and generative neural networks can help in these two critical areas of computation in experimental particle physics research: track reconstruction and event simulation.

Biogram: Bartosz Soból is a first-year PhD student in Technical Computer Science at Jagiellonian University.

Title: Artificial Intelligence in Industry 4.0: Data, Models, and Knowledge

Abstract: Industry 4.0 is a paradigm shift, or the next industrial revolution, according to some analysts. It is also closely related with the Internet of Things (IoT), Cyber Physical System (CPS), and with information and communications technology (ICT) in general. One of the aspects of I4.0 is the use of extensive monitoring equipment including sensor networks for monitoring of industrial assets. The premise of I4.0 is that the gathered sensor data may serve as means to support decision making in the industrial setting. However, a proper analysis and use of this data poses a number of challenges. First of all, the characteristics of this data make it a typical Big Data with big volume, velocity, variety. Furthermore, typical analytical methods are not applicable. This is why specific data mining methods must be used, with specific machine learning algorithms properly selected and configured. However, in most of the real-life cases the use of machine learning is not enough. Extensive domain knowledge has to be taken into account to prepare as well as interpret the mining process of the industrial data. This requires a development of complex hybrid AI-based approaches combining ML methods with model and knowledge-based ones. Finally, I4.0 imposes number of specific requirements and tasks to be solved by these approaches. For last three years, the GEIST research group has been involved in two international research project funded by the CHIST-ERA scheme. In the most recent one, the XPM project, we are developing novel methods for predictive maintenance tasks in I4.0 using methods of eXplainable AI (XAI). In the first one, the PACMEL project, we have been developing novel methods for high level knowledge-driven analysis of sensor data, as well as conformance checking of business and industrial processes. This short presentation will introduce the challenges as well as results of both projects.

Title: AI with psychology – a few words on affective adaptation and personalisation of intelligent systems

Abstract: Does your smartphone understand how you feel? When you are irritated does it just go silent and stop annoying you? Such technology is not there yet, but the expansion of intelligent systems into new fields of activity means that they are spending more and more time with us. And that raises the need to implement not only algorithms tailored to solve tasks, but also to understand what the user is feeling. This talk will highlight the key findings of research conducted in this area by the AfCAI team (https://afcai.re/): How to understand emotions? How to collect data? How to train models? Why is this technology not yet working and what can be done to improve its effectiveness?

Biogram: Krzysztof Kutt, PhD, is an assistant professor at the Jagiellonian University. He received BSc and MSc degrees in Computer Science at AGH-UST. In 2018 he defended his PhD thesis on methods and tools for collaborative knowledge engineering at AGH-UST. He also received MA degree in Psychology from Jagiellonian University. Currently, as a computer scientist and a psychologist, he is trying to combine these two disciplines together to create something new and better. His research activities focus on the knowledge engineering (knowledge graphs, data semantization), affective computing (collecting and processing sensory and contextual data related to emotions) and ways of user interaction with information systems (including BCI and Neurofeedback systems).

Title: Telepresence and simulators – modern use of Virtual Reality in robotics and training with possible application of AI

Abstract: Research on virtual reality has been conducted for over half a century. At that time, the development of technology meant that the possibilities of immersion in a virtual environment were much greater, and the potential spectrum of practical application was becoming broader and broader. Additionally, the decreasing cost makes using these technologies more and more justified also from an economic point of view. Three different VR applications will be presented: remote control of mobile robots using the telepresence concept, training a group of firefighters, and building simulators of self-propelled mining machines. The possibilities of improving training simulations by using AI to modify the course of the training scenario in real-time based on the actions taken by the trainee will also be indicated.
