Jiming Liu is Chair Professor in Computer Science (04/2010-present), and was previously Associate Vice-President (Research) (05/2017-12/2019), at Hong Kong Baptist University. He received his M.Eng. and Ph.D. degrees in Electrical Engineering from McGill University (Centre for Intelligent Machines) in Canada. His current research interests include Data Analytics and Machine Learning, Complex Networks and Systems, Web Intelligence (WI), Autonomy-Oriented Computing (AOC) Paradigms, and AI-Enabled Epidemiology and Practice. He is a Fellow of the IEEE. Prof. Liu has served as Editor-in-Chief of Web Intelligence Journal (IOS), and Associate Editor of IEEE Transactions on Cybernetics, IEEE Transactions on Knowledge and Data Engineering, Data and Information Analytics (AIMS), and Computational Intelligence (Wiley), among others. He was Chair of IEEE Computer Society Technical Committee on Intelligent Informatics (TCII).
1. Demystifying deep learning: An information-theoretic framework
Deep learning has achieved incredible success in various challenging predictive spatiotemporal analytics (PSTA) tasks. However, given a specific PSTA task, how to appropriately determine the desired architecture of a deep learning model remains a mystery. To demystify the power of deep learning for PSTA in a theoretically sound and explainable way, we provide a comprehensive framework for deep learning model design and information-theoretic analysis. In so doing, we tackle an important open question in deep learning, that is, how to theoretically determine the necessary and sufficient configurations of a deep learning model, with respect to given learning datasets.
2. How COVID-19 transmits: A social-contact characterization
COVID-19 has spread to 6 continents. Gaining a deeper understanding of what may have happened could potentially inform mitigation strategies in disease-emerging countries. This work addresses how COVID-19 spreads among different populations and the corresponding impacts on disease control, e.g., with/without interventions. We approach this question by examining age-specific social contact-based transmissions. The results show that the social contact-based analysis can readily explain the underlying disease transmission patterns and associated potential risks. This work has uncovered the ins and outs of COVID-19 outbreaks, which could have practical implications to mitigation strategy planning in various countries and regions.

AI Surveillance of Epidemics
Time is of the essence in preventing a disease outbreak. Prof Liu Jiming, Chair Professor of the Department of Computer Science at HKBU, and his team developed an actuve surveillance ystem with machine learning and data-driven modeling, which can predict the spread of disease and inform poilcy decisions.
