Title: Algorithms for multi-group learning

Abstract: Multi-group learning is a formal learning criterion that is concerned with the conditional risks of predictors within subgroups of a population. The criterion addresses practical concerns such as subgroup fairness and hidden stratification. I’ll talk about the structure of solutions to the multi-group learning problem, as well as some simple and near-optimal algorithms for the learning problem. 

This talk is based on a number of joint works with Navid Ardeshir, Siva Balakrishnan, Noah Bergam, Samuel Deng, Jingwen Liu, Chris Tosh, Lujing Zhang.

3:30pm - Pre-talk meet and greet teatime - 219 Prospect Street, 13 floor, there will be light snacks and beverages in the kitchen area.  For more details and upcoming events visit our website at https://statistics.yale.edu/calendar.
