Abstract:

The problem of learning to rank from a set of pairwise comparisons has been studied widely in several research communities including ML, theoretical computer science, operations research, statistics, etc. In this talk, Professor Rajkumar will give an introduction to this problem and talk about several provably optimal algorithms for this problem along with some exciting structural results that involve understanding classes of tournament graphs. The pre-requisites for the talk are minimal and will be covered during the talk.
