Speech Title: The Future of AI: From Unconscious Models to Conscious Reasoning and Emotional Intelligence
In this presentation, I first highlight the advancements in foundation models in the past decade, and present their impact on various domains. I then explore some known issues such as a lack of robustness, interpretability, and generalization. It's argued that AI models have successfully modeled human unconsciousness to a certain extent. However, to enable AI to think and plan, a proposition is made [1] to model consciousness on top of unconsciousness. The discussion begins with the definition of consciousness, the exploration of the transitional mechanisms between consciousness and unconsciousness, theories of consciousness, and the differentiation between attention and consciousness. A functionalist approach is adopted to formulate a model of consciousness that encompasses perception, awareness, attention, critical thinking, creative thinking, and emotional intelligence. An illustration is provided on how these consciousness capabilities can be developed in foundation models through the careful design of prompt templates. Specifically, how the Socratic method [2], along with inductive, deductive, and abductive reasoning, can facilitate critical thinking and reading via prompt-template engineering is demonstrated. The integration of emotional intelligence to guide exploratory thinking, with ethical safeguards that respect individual and cultural values, is also discussed.

His most recent textbook in foundational machine learning “Elements of Dimensionality Reduction and Manifold Learning” was published by Springer Nature in February 2023. He was honored in 2021 by the IEEE Vehicular Technology Society (VTS) with the IEEE VTS Best Land Transportation Paper Award for his pioneering work on improving traffic flow prediction with weather Information in connected cars using deep learning and AI. His recent work on federated learning in communication systems earned him and his co-authors the 2022 IEEE Communication Society’s MeditCom Conference Best Paper Award. Fakhri is a Fellow of the IEEE, a Fellow of the Canadian Academy of Engineering, a Fellow of the Engineering Institute of Canada. He served as a Distinguished Lecturer for the IEEE and a Kavli Frontiers of Science Fellow. Fakhri received the Ing. Dip degree in electrical engineering from the School of Engineering of the University of Tunis,Tunisia and the Ph.D. degree from the University of Illinois Urbana-Champaign, USA.

Speech Title: Generative vs. Operational Artificial Intelligence: Opportunities and Challenges
The talk presents recent trends and major advances accomplished lately in the field of Artificial Intelligence (AI), specifically Operational and Generative Artificial Intelligence (OAI/GAI). As demonstrated by impressive accomplishments made in the field (such as ChatGPT and other generative AI based engines) and due to fundamental advances made in the field of machine learning and artificial intelligence, experts are predicting we are at the cusp of a new technological revolution. It is expected that AI will grow the world GDP by up to 20% by 2025. This amounts to more than 15 Trillion dollars of growth over the next few years. These developments have impacted significantly technological innovations in the field of Internet of Things, self-driving machines, powerful chat bots, virtual assistants, human machine intelligent interface, large language models, real-time translators, cognitive robotics, virtual care systems, eHealth and Fintech, to name a few. Although AI constitutes an umbrella of several interrelated technologies, all of which are aimed at imitating to a certain degree intelligent human behavior or decision making, deep learning algorithms are considered to be the driving force behind the explosive growth of AI and their applications in almost every scientific and technological sector: disease diagnosis, remote health care monitoring, financial market prediction, self-driving vehicles, social robots with cognitive skills, intelligent manufacturing, surveillance, cybersecurity, intelligent transportation systems, to name a few. The talk highlights the milestones that led to the current growth in AI, OAI and GAI, the role of academic institutions and discusses some of the major achievements in the fields. It enumerates as well real challenges when these innovations are mis-used leading to potential negative effects on society and end-users.

Speech Title: Can Federated Learning be Responsible ?
Federated learning (FL) is an emerging distributed collaborative learning paradigm by decoupling the learning task from the centralized server to a decentralized population of edge clients. One of the attractive features of federated learning is its default client privacy, allowing clients to jointly learn a global model while keeping their sensitive training data locally and only share local model updates with the federated server(s). However, recent studies have revealed that such default privacy is insufficient for protecting the confidentiality of client training data and the safety of the global model. This keynote will describe model leakage risks and model poisoning risks in distributed collaborative learning systems, ranging from image understanding, video analytics, to large language models (LLMs), and provide insights for risk mitigation methods and techniques, ensuring responsible Federated Learning.
