Automated Security Intelligence
Every day it becomes harder to guarantee enterprise security. Sophisticated attacks are launched from economically-driven, well-organized attackers. Systems are complex and evolving, and it is difficult, if not impossible, to keep track of security vulnerabilities and prepare every employee with enough knowledge and skills. To address these challenges, we propose the automated security intelligence project, inspired by the words of Sun Tzu: “If you know your enemies and yourself, you can win a hundred battles without a single loss.”

NGLA: Next Generation Log Analytics
Computer systems generate a huge number of heterogeneous logs which provide rich contextual information about system status and are critical sources for system monitoring and diagnosis. Manually interpreting those logs is not effective, however, due to their large volume and complicated domain-specific syntax and semantic knowledge.

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.

Dynamic Graph Analysis
In many big data applications, data with complex structures are connected for their explicit/implicit interactions and are naturally represented as graphs/networks. The world is full of complex and dynamic interactions between diverse objects. The flood of dynamic graph data poses great computational challenges and entails interdisciplinary collaborations.

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.
