Skill Acquisition Learning (SAiL)
This project aims to learn skills by mimicking experts’ behaviors in given tasks. The proposed SAiL engine is trained to perform action prediction tasks from demonstrations by learning a mapping function between observed states and actions. The main challenges in real applications, medical and health care, for example, are that the collection of such experts’ demonstrations is very expensive and It takes a large amount of time and money for expert training.

Safe and Trustworthy AI
By leveraging big data and deep learning, in recent years, AI technologies have made significant progress. They have been adopted in many applications including malware detection, image classification, and stock market prediction. As our society becomes more automated, more and more systems will rely on AI techniques. And instead of augmenting human decisions, some AI systems will make their own decisions and execute autonomously.

Multimodal Data Analysis
Multimodal data are prevalent in industrial monitoring, finance and healthcare. In particular, time series are often tagged with text comments from experts that provide layman users with the domain knowledge to understand the charts. Texts give the patterns qualitative meaning while time series makes the words quantitative. Analyzing the relationship between different data types is the key to unraveling the hidden structure of such data.
