Title: AI inference acceleration on FPGA
Abstract: Artificial intelligence and neural networks are constantly applied in all sorts of tasks involving data processing. Emerging models are deployed on different kinds of computing platforms: from edge computing, through the cloud, and ending with HPC. Modern FPGA-based accelerators and SoCs aim to fulfill different needs in all of the above levels such as high throughput, low latency, high energy efficiency, and flexibility. New software stacks are developed to expose high-level interfaces for preparing, optimizing, and deploying existing or custom, implemented in standard machine learning frameworks such as PyTorch or TensorFlow, models on FPGA devices. In this talk, I will present modern solutions for accelerating the inference of neural network models on FPGAs as well as examples of usage done by us at the JU and from others.

Title: Moral Improvement with Video Games
Abstract: In this talk I will report on a series of experiments with video games that involve moral decision-making and that showcase how explainable machine learning and artificial intelligence methods, so ones that involve relatively simple models, can be used to validate hypotheses about cognitive and affective processes involved in those decisions. What binds this empirical work together is a larger agenda that has been the focus of my research for a number of years and which seeks to find ways to improve moral decision-making mechanisms (both cognitive and affective) by non-invasive means. This larger project will frame the presentation of experimental results.

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.

Abstract: EXplainable Artificial Intelligence (XAI) often boils down to presenting the role of variables in the ML model. In our work, we want to show that thanks to XAI you can achieve much more. We propose InXAI framework, which purpose is to help machine learning experts incorporate explainability into their models. With InXAI, we conducted an experiment that consisted in optimizing the ensemble of binary classifiers in such a way that it would be characterized by better XAI evaluation measures, while maintaining the basic metrics of the model, such as Accuracy. In the second part of my presentation, I will show the current directions of my work on XAI in the context of Time Series data.

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.

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.

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?

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.

Title: Financial modeling with applications of machine learning and explainable AI.
Abstract: Financial modeling is a general term that can cover many different processes carried out throughout the financial system. One of the broad definitions of financial model is that it is anything that is meant to calculate, forecast, or estimate financial numbers. Its applications can be found in all kinds of financial institutions, like banks, investment funds, insurance companies, but also non-financial ones, like regular companies, which forecast incomes, outcomes, cash flows etc. The presentation will focus on and explain some of its more specific fields, like financial instruments pricing (derivatives in particular) or risk modeling, tell about the purpose of these and present challenges arising in them. Next, it will show applications of machine learning and explainable AI in the mentioned processes and fields, obstacles which come with applying them and current solutions. The presentation will also cover available financial data sources that may be used for research purposes.
