Abstract
The costs of mental disorders are a great burden on health systems.
Despite the concerted efforts of the machine learning community and the application of advanced experimental techniques such as functional magnetic resonance (fMRI), near-infrared spectroscopy (NIRS), and high-density EEG/MEG, we have yet to identify objective biomarkers that can be utilized in clinical settings. Ideally, we should be able to employ cost-effective methods, like basic EEG systems in a resting state, for the early and precise diagnosis of disorders such as autism, PTSD, and schizophrenia, among others.
This presentation will summarize the state-of-the-art in this field, delve into the challenges faced, issues with generalization, and the shortcomings of deep learning to provide effective features for the characterization of brain neurodynamics. A promising alternative proposed by our group combines EEG microstates with recurrence quantification and topological data analysis for a practical and potentially game-changing solution.

Abstract
Even simple cyberattacks can impair the operation and performance of network systems substantially for many hours and sometimes days, and also increase the system's energy consumption. Their impact on data security, and the effects of the malware that they convey and install, are also well known. Thus there is a widespread need for accurate cyberattack detection, and rapid reaction and mitigation when attacks occur. On the other hand, the detection must avoid false alarms, to avoid impairing the smooth operation of a system which is not under attack. Thus considerable research has been conducted in this important field. Our presentation will briefly introduce the subject, and then focus on some recent results from the last 7-8 years, that are based on the Random Neural Network (RNN). The mathematical model will be described, and its extensions and deep learning algorithms will be discussed in the context of cyberattack detection and mitigation. The presentation will then focus on practical applications illustrated with different cyberattack datasets, showing the high accuracy and low false alarm rates that can be achieved. Measurements of active control schemes for attack mitigation will also be shown. Finally we will also show how the RNN can be used with Reinforcement Learning and SDN (Software Defined Networks), to dynamically control an Edge System that optimises Security, QoS and Energy Consumption.

Abstract
Large Language Models are prone to biased predictions and
hallucinations, underlining the paramount importance of understanding
their model-internal reasoning process. However, achieving faithful
explanations for the entirety of a black-box transformer model and
maintaining computational efficiency is difficult. This talk will
present a recent extension of the Layer-wise Relevance Propagation
(LRP) attribution method to handle attention layers, which addresses
this challenge effectively. Our method is the first to faithfully and
holistically attribute not only input but also latent representations
of transformer models with the computational efficiency similar to a
singular backward pass. Since the LRP is a model-aware XAI method, it
not only identifies the relevant features in input space (e.g., pixels
or words) but also provides deep insights into the model’s
representation and the reasoning process. Through extensive
evaluations against existing methods on Llama 2, Flan-T5 and the
Vision Transformer architecture, we demonstrate that our proposed
approach surpasses alternative methods in terms of faithfulness and
enables the understanding of latent representations, opening up the
door for concept-based explanations.

Abstract
Monocular depth estimation is a classical task in computer vision, which aims to estimate the distances between the objects in the environment and the agent itself. Recently, deep-learning-based depth estimation methods have obtained significant advancements. The self-supervised framework uses geometric constraints between images as the main supervisory signal and hence the training data is much more available. This talk will introduce the main accomplishments and recent developments in self-supervised monocular depth estimation. Then, the recent work performed by the speaker’s group will be presented, which focuses on improving the accuracy and transferability of the self-supervised monocular depth estimation model. Finally, the prospects for future development will be discussed.

Abstract
In the current era, multi-agent systems have witnessed rapid development, showcasing immense potential in domains such as energy-economic dispatch, machine learning, and collaborative operations of complex systems. This talk introduces the optimization and games in multi-agent systems. In the context of privacy protection and asynchronous computation, the talk explores reducing the communication load in distributed optimization through various event-triggered mechanisms. Considering the system's inherent uncertainties and the model’s interpretability in decision-making, the talk also delves into data-driven decision-making methods. Swarm game theory contains two primary categories: analytical games and reinforcement learning (RL)-based games. Analytical games focus on constructing mathematical models among swarm members, utilizing these models to devise effective strategies through thorough analysis. On the other hand, RL-based games prioritize the application of reinforcement learning techniques, emphasizing the role of trial and error in the strategic decision-making process to refine and perfect game strategies.

Abstract
This tutorial discusses original research connecting generative AI and Evolutionary Computation (EC) fields. Through engaging demonstrations and discussion, the aim is to bring together experts from basic EC research, experts from different EC application areas, and experts or enthusiasts in Generative AI and large language models. The aim is to present a unique combination of techniques and deeper insights into the usability, prompting, and reasoning of the outputs of Generative AI and its impact on the design, selection, performance (improvements), efficiency, and understanding of EC techniques. Such research has become a vital part of science and engineering at the theoretical and practical levels.
The original contribution of this tutorial will be the presentation of the metaheuristics design procedure, either as a whole or as its individual parts, using various partial approaches, one-shot or iterative automated calls, specific prompt engineering and also together with a discussion of the possibilities of incorporating other features of the search space of the problem to be solved (optimized). The tutorial will conclude with reflections on the broader implications of integrating LLMs like GPT-4 in metaheuristic development. We'll discuss the potential future directions this research could take and how it might shape the evolution of algorithmic problem-solving in various domains.
