Speech Title: New artificial intelligence technologies in healthcare

Abstract: Artificial intelligence has significantly influenced the health sector for years by delivering novel assistive technologies from robotic surgery to versatile biosensors that enable remote diagnosis and efficient treatment. While the COVID-19 pandemic is devastating, the uses of AI in the healthcare sector are dramatically increasing and it is a critical time to look at its impact in different aspects. In this talk, I will introduce the application of new deep learning models in medical image understanding. Then, I will discuss Parkinson’s disease (PD) whilst investigating the behaviour analysis of PD mice. I also present the use of machine learning technologies in sentiment analysis, followed by the discussion on several challenges.

Speech Title: Efficient and robust direct sampling-type methods for general ill-posed inverse problems

Abstract: In this talk we present a survey of recent developments of direct sampling type methods (DSMs) for solving general linear and nonlinear inverse problems of partial differential equations. The sampling type methods were proposed earlier for solving inverse acoustic scattering problems with far-field or near-field data [7][8], then developed for inverse electromagnetic scattering problems [6], and further extended for several representative non-wave type inverse problems, including electric impedance tomography[5], diffusive optical tomography [3], inversion of Radon transform [1], as well as recovering moving inhomogeneous inclusions [4]. DSMs have also been demonstarted recently to be applicable to the simultaneous reconstruction of inhomogeneous inclusions of different physical nature [2]. The DSMs are computationally cheap, highly parallel, and robust against noise, particularly applicable to the cases when very limited data is available. Motivations, principles and justifications of DSMs are addressed in this survey talk. Numerical experiments are demonstrated for various inverse problems. There are intensive studies of this type of numerical methods, and some of the references for those most representative inverse problems are listed below.

These research projects were supported by Hong Kong RGC General Research Fund (Projects 14306921 and 14306719).

Speech Title: Leveraging AI for Smart Transportation

Abstract: Mitigating traffic congestion and improving safety are the cornerstones of transportation within smart cities. Current practices collect and analyze data from sensors and video processing and then process it offline. Hence, they are limited in proactively reducing traffic fatalities and preventable delays at intersections. We are developing real-time artificial intelligence algorithms and software to analyze video feeds from cameras and fuse them with ground sensor data to develop deep learning based digital twins that mimic traffic behavior both at an intersection and at the city level. We are also using the resultant output to develop technologies that will quantitatively measure and rank intersections by safety, to transmit information about unsafe behavior to connected vehicles and pedestrians in real-time to prevent accidents, and to optimize signal timing to reduce congestion.

Each of these advances are presently being field tested at intersections in the City of Gainesville and in Seminole County. The overall effort is geared toward developing transportation solutions for leading edge 21st century smart cities.
