Distributed Intelligence in the Computing Continuum

Modern distributed systems also deal with uncertain scenarios, where environments, infrastructures, and applications are widely diverse. In the scope of IoT-Edge-Fog-Cloud computing, leveraging these neuroscience-inspired principles and mechanisms could aid in building more flexible solutions able to generalize over different environments. A captivating set of hypotheses from the field of neuroscience suggests that human and animal brain mechanisms result from a few powerful principles. If proved to be accurate, these assumptions could open a deep understanding of the way humans and animals manage to cope with the unpredictability of events and imagination.

Data Stream Methodology For Speeding Up Training Deep Neural Networks

Speeding up the training of artificial neural networks is crucial due to the growing complexity of models and expanding datasets. Researchers worldwide are working on different methods to make this training process faster. In the lecture, it will be shown how to develop faster deep neural network learning algorithms by making use of the data stream methodology. First, the basic concepts of stream data mining are outlined with a special emphasis put on concept drift – the phenomenon describing the time-varying nature of streaming data. Next, a novel paradigm for faster deep neural network learning is described and its performance is investigated and illustrated, showing our ongoing research results.

Leszek Rutkowski received the M.Sc., Ph.D., and D.Sc. degrees from the Wrocław University of Technology, Wrocław, Poland, in 1977, 1980, and 1986, respectively, and the Honoris Causa degree from the AGH University of Science and Technology, Kraków, Poland, in 2014. He is a professor at the Systems Research Institute of the Polish Academy of Sciences, Warsaw, Poland, and at the AGH University of Krakow, Poland. His research interests include data stream mining, big data analysis, neural networks, agent systems, fuzzy systems, image processing, pattern classification, and expert systems.

Utilizing Machine Learning and Social Network Analysis to Counter Disinformation on Online Social Networks

The proliferation of disinformation and misleading content within online social networks (OSNs) has emerged as a pressing concern, posing detrimental effects at personal, societal, and national levels. The unchecked and swift dissemination of such content has fostered an environment conducive to the amplification of falsehoods, rumors, propaganda, and hoaxes, thereby significantly impacting economic, political, and public health landscapes in recent years. Tackling this multifaceted challenge necessitates a holistic, collaborative approach involving various stakeholders, including individuals, media entities, governmental bodies, technology firms, and researchers. This keynote seeks to shed light on the associated complexities and delve into the utilization of Machine Learning, and Social Network Analysis techniques in countering disinformation. Specifically, the keynote will center on two primary domains: Natural Language Processing (NLP) and Multimodal Deep Learning (DL) architectures. In the realm of NLP, emphasis will be placed on the facter-check architecture, a solution employing ensembles and deep learning rooted in Transformer technology. This framework showcases the effective integration of NLP and SNA methodologies in identifying misleading content and tracing its dissemination across OSNs. Conversely, the presentation will also spotlight novel deep learning models tailored for the analysis and fusion of multimodal information, encompassing images and textual information (comments, posts, metadata). Analyzing posts poses a formidable challenge due to the diverse modalities of information, including textual and visual components. Finally, the keynote will explore future trends and challenges associated with the detection and mitigation of misinformation, underscoring the ongoing efforts in combating this pervasive issue.

Multimodal Graph Generative AI and applications to biomedical domain

Graph generative models are recently gaining significant interest in current application domains. They are commonly used to model social networks, knowledge graphs, molecules and proteins. In this talk we will present the potential of graph generative models and our recent relevant efforts in the biomedical domain. More specifically we present a novel architecture that generates medical records as graphs with privacy guarantees. We capitalize and modify the graph Variational autoencoders (VAEs) architecture. We train the generative model with the well known MIMIC medical database and achieve generated data that are very similar to the real ones yet provide privacy guarantees. We achieve there as well promising results with potential for future application in broader biomedical related tasks. Finally we present ongoing research directions for multi modal generative models involving graphs and applications to protein function text generation – the prot2text model.
