Presentation Title:  Introduction to UA-TRIPODS; Interaction Selection for Big Data

Abstract:  My talk consists of two parts. The first part will provide an overview of UA-TRIPODS, the new NSF-funded data science institute at UA. I will present research, education, and outreach activities of UA-TRIPODS, and as well as collaboration and funding opportunities provided by the institute. In the second part, I will present one of my recent works on the problem of interaction selection for high-dimensional data in supervised learning. A new regularization method, including a scalable path-building algorithm (RAMP) and some theoretical results, will be introduced. Some applications of the new method in big data analytics will be presented as well.
