AI and Big Data to Advance Well-being and Society
The University of Hong Kong, under the HKU-Cambridge AI to Advance Well-being and Society Research Platform, led by Professor Victor O.K. Li and Dr Jacqueline C.K. Lam, has been performing research on AI technologies and its application to pressing societal problems, especially those problems related to environment and health. In this talk, we discuss one of our recent research results, in which we apply AI and big data technologies to answer the following question: Are the socially deprived exposed to a higher level of PM2.5 pollution in HK? Our study develops an AI and big data model, utilizing ubiquitous urban dynamics closely related with air pollution, including ambient pollutants concentration, traffic, meteorology and urban morphology to provide a fine-grained estimation of air pollution in HK. We investigate if there is any differential distribution in PM2.5 pollution across people residing in constituency areas (CAs) of different levels of social deprivation (SD). We conclude there is a statistically significant, positive relationship between ambient PM2.5 concentration and SDI in HK, based on the SDI and mean PM2.5 exposure values derived from 412 Constituency Areas (R2 = 1.4%, p-value < 0.01, based on ordinary least squares). Areas exposed to high air pollution and high social deprivation can be found in Yuen Long, Kwun Tong, Sham Shui Po and Wong Tai Sin. Our study provides the basis for evidence-based environmental decision-making in Hong Kong, aiming to improve the quality of life of the socially deprived citizens. Our work has been reported by 30+ local and overseas newspapers and media.
Victor O.K. Li received SB, SM, EE and ScD degrees in Electrical Engineering and Computer Science from MIT. Professor Li is Chair of Information Engineering and Cheng Yu-Tung Professor in Sustainable Development at the Department of Electrical & Electronic Engineering (EEE) at the University of Hong Kong (HKU). He is the Director of the HKU-Cambridge Clean Energy and Environment Research Platform, and of the HKU-Cambridge AI to Advance Well-being and Society Research Platform, which are interdisciplinary collaborations with Cambridge University. He was the Head of EEE, Assoc. Dean (Research) of Engineering and Managing Director of Versitech Ltd., the technology transfer and commercial arm of HKU.
