HADD Research Group

Auto Column in HTML

In the matH of Algorithms, Data & Decisions (HADD) research group, we consider problems motivated by the study of real-world data. We consider the mathematics of data, models for making decisions with data, and methods for training such models. See the Research and Publications pages for more details!
