Cyber-physical Systems Software Engineering Trustworthy AI
Research
AI-enabled Cyber-physical systems (AI-CPSs) are integrated systems in which traditional software units, Artificial Intelligence (AI) components, and physical plants are intertwined to collaboratively perform complex tasks. Such advanced but complex systems have been widely deployed in a diverse spectrum of industrial applications to deliver state-of-the-art (SOTA) safety, efficiency, and system robustness.
However, two questions keep me up at night and encourage me to explore further, namely, (1) How to safeguard the quality of sophisticated AI-CPS? and (2) What is the best practice of cyber-physical interaction?
My research is devoted to investigating these two questions in three stages:
(1) design AI-aware testing and evaluation techniques to reveal the capability of AI-CPSs,
(2) propose novel analysis strategies to understand the behavior characteristics of AI components w.r.t the physical world, and
(3) develop enhancement solutions to improve the overall safety and reliability of the system across domains.
