Abstract: A brain-computer interface (BCI) enables a user to communicate directly with an external device, e.g., a computer, using brain signals. It can be used to research, map, assist, augment, or repair human cognitive or sensory-motor functions. A closed-loop BCI system performs signal acquisition, temporal filtering, spatial filtering, feature engineering and classification, before sending out the control signal to an external device. Transfer learning (TL) has been widely used in EEG-based BCIs to reduce the calibration effort for a new subject, greatly increasing their utility. This tutorial describes how TL can be considered in as many components of a BCI system as possible, and introduces a complete TL pipeline for EEG-based BCIs. Deep learning approaches are also fully evaluated with classic and state-of-the-art domain adaptation approaches with end-to-end neural networks for both offline and online BCI applications. Examples on multiple datasets demonstrate the advantages of considering TL in multiple components of EEG-based BCIs. Especially, integrating data alignment and sophisticated TL approaches can significantly improve the classification performance, and hence greatly reduces the calibration effort.

Abstract: Today computing devices like laptops, mobile phones, smart devices, etc., have penetrated very deep into our modern society and have become an integral part of our daily lives. Currently, more than half of the world’s population uses computers/mobile devices for their professional/personal needs. However, these computing devices are targeted by malware designers encouraged by profits/gains associated with the attack. According to a recent report, monetary losses due to cybercrime are expected to reach 10 trillion dollars annually by 2025. The primary role in providing defense against malware attacks is designed and developed by the anti-malware community (researchers and the anti-virus industry). Traditionally anti-viruses are based on the signature, heuristic, and behavior based detection engines. However, these engines are unable to detect next-generation polymorphic and metamorphic malware. Thus researchers have started developing malware detection engines based on machine learning to complement the existing anti-virus engines. However, there are many open research challenges in these models like adversarial robustness, explainability, fairness, etc., which we are going to discuss in detail during the tutorial.

Abstract: Combinatorial problems refer to those applications where we either look for the existence of a consistent scenario satisfying a set of constraints (decision problem), or for one or more good/best solutions meeting a set of requirements while optimizing some objectives (optimization problem). These latter objectives include user’s preferences that reflect desires and choices that need to be satisfied as much as possible. Moreover, constraints and objectives (in the case of an optimization problem) often come with uncertainty due to lack of knowledge, missing information, or variability caused by events, which are under nature’s control. Finally, in some applications such as timetabling, urban planning and robot motion planning, these constraints and objectives can be temporal, spatial or both. In this latter case, we are dealing with entities occupying a given position in time and space.  Because of the importance of these problems in so many fields, a wide variety of techniques and programming languages from artificial intelligence, computational logic, operations research, and discrete mathematics, are being developed to tackle problems of this kind. While these tools have provided very promising results at both the representation and the reasoning levels, they are still impractical to dealing with many real-world applications. Using the Constraint Satisfaction Problem (CSP) formalism, we will explore several exact and approximate solving techniques to address the challenges and limitations listed above.

Abstract: Humans are social beings and people cannot live alone. Computational social simulation is a way to reproduce a real-world society and study the behaviour of people in that society using computer-based systems. Computational social simulation is a long-term, cutting-edge topic in the interdisciplinary field where information technology, computer science, social science, and sociology overlap. Role-Based Collaboration (RBC) has been proposed as a computational approach to facilitating collaboration. It utilizes roles as underlying mechanisms to support collaboration by taking advantage of roles. It is divided into several phases: role negotiation, role assignment, role execution, and role transfer. RBC and its related components are an abstract model, which is a perfect mapping for social activities, because Social and economic systems are typical collaboration systems. The Environments – Classes, Agents, Roles, Groups, and Objects (E-CARGO) model, which has been developed into a general model for complex systems have a good match for the requirements of computational social simulations. In this talk, we establish the fundamental requirements for social simulation and demonstrate that RBC, E-CARGO, and the subsequent Group Role Assignment (GRA) optimization model are highly qualified to meet these requirements. Based on E-CARGO and GRA, we present a new approach to social simulation with E-CARGO related components, models, and algorithms. This tutorial also illustrates several interesting case studies of computational social simulations.

Abstract: The subject of this tutorial links Natural Language Processing, Interaction and linguistics analysis and knowledge representation. Researchers and PhD students that want to discover social media, e-mails and document analysis and cognitive sharing are interesting on this area. In fact, AI research use generally NLP and TextMining and statistics, or Knowledge engineering and semantic representation. But they are aware, Interactions analysis that uses Prama-linguistics techniques belong to social and human science. In this tutorial, we present new techniques based on linguistics and pragma-linguistic that help to identify not only semantic relations but also actors’ intentions. We show also how to combine these techniques with knowledge engineering in order to restitute the meaning of interactions. Examples on analyzing websites, e-mails and discussion forums will be presented.  Finally, Tutorial attendees will apply some of this analysis techniques in given exercises.

Abstract: The ultimate goal of multi-objective optimization is to help a decision maker (DM) identify solution(s) of interest (SOI) achieving satisfactory trade-offs among multiple conflicting criteria. This can be realized by leveraging DM’s preference information in evolutionary multiobjective optimization (EMO). No consensus has been reached on the effectiveness brought by incorporating preference in EMO (either a priori or interactively) versus a posteriori decision making after a complete run of an EMO algorithm. In this tutorial, I will present a series of experimental results show that preference incorporation in EMO does not always lead to a desirable approximation of SOI if the DM’s preference information is not well utilized, nor does the DM elicit invalid preference information, which is not uncommon when encountering a black-box system. To a certain extent, this issue can be remedied through an interactive preference elicitation. Last but not the least, we find that a preference-based EMO (PBEMO) algorithm is able to be generalized to approximate the whole PF given an appropriate setup of preference information.

Abstract: The Internet of Things (IoT) paradigm enables various smart objects to be connected, this allows us to interact with our environment in an intelligent way. It is believed that low power and ultra-low power sensors would outnumber any other IoT devices by 2030. To achieve the full potential of IoT applications, AI techniques are required to analyze the sensor data on the edge for real-time analytics, reduced latency, and less privacy concern. Low power consumption edge AI also creates significant opportunities for green AI and sustainable IoT research, which aligns with the conference’s theme of “Improving the quality of life”.  In this tutorial, we will first provide a comprehensive overview of low power sensors and compare various IoT communication protocols. We will walk through the detailed end-to-end data integration steps from sensors to the loud data platform using real life award-winning smart cities examples. Since low power sensors are constrained by power and processing resources, integration with computationally intensive Machine Learning (ML) for intelligent processing and decision making becomes a unique challenge. This tutorial will review various methods for applying ML and deep learning to low power sensor solutions. Different hardware and software options will be discussed including bio-inspired chipsets, traditional centralized learning, federated ML, pruning and TinyML for edge computing. We will demonstrate the latest design of our acoustic sensor with edge ML capability for real time sound classification. Development trend and future research opportunities for edge AI and IoT will also be presented.

Abstract: A driving force for the realization of a sustainable energy supply is the integration of renewable energy resources. Due to their stochastic generation behaviour, energy utilities are confronted with a more complex operation of the underlying power grids. Additionally, due to technological developments, controllable loads, integration with other energy sources, changing regulatory rules, and market liberalization, the system’s operation needs adaptation. Proper operational concepts and intelligent automation provide the basis to turn the existing power system into an intelligent entity, a smart grid. While reaping the benefits that come along with those intelligent behaviours, it is expected that system-level developments and testing will play a significantly larger role in realizing future solutions and technologies. Proper validation approaches, concepts, and tools are partly missing until now. This tutorial aims to tackle the above-mentioned requirements by introducing validation methods and tools for validating smart grids and energy systems.
