Computer Science/Discrete Mathematics Seminar II

Coboundary and Cosystolic Expansion
10:30am|Simonyi Hall 101 and Remote Access

Coboundary expansion and cosystolic expansion are generalizations of edge expansion to hypergraphs. In this talk, we will first explain how the generalizations work. Next we will motivate the study of such hypergraphs by looking at their applications...


Computer Science/Discrete Mathematics Seminar I

Online Omniprediction
Sumegha Garg
11:15am|Simonyi 101 and Remote Access

A recent line of work has shown a surprising connection between multicalibration, a multi-group fairness notion, and omniprediction, a learning paradigm that provides simultaneous loss minimization guarantees for a large family of loss functions [GKR...
