TIME:  4:30pm

LOCATION:  Sherrerd Hall room 101

SPEAKER:  Sebastien Bubeck, Princeton/Microsoft

TITLE: The entropic barrier: a simple and optimal universal self-concordant barrier

ABSTRACT:
A fundamental result in the theory of Interior Point Methods is Nesterov and Nemirovski's construction of a universal self-concordant barrier. In this talk I will introduce the entropic barrier, a new (and in some sense optimal) universal self-concordant barrier. The entropic barrier connects many topics of interest in Machine Learning: exponential families, convex duality, log-concave distributions, Mirror Descent, and exponential weights.
BIO:
Sebastien Bubeck is an assistant professor in ORFE at Princeton University, and a researcher in the Theory Group at Microsoft Research, Redmond.
