On behalf of the Scientific Committee of the de Finetti Risk Seminars, we are glad to invite you to participate at the following Lecture

Samuel Cohen University of Oxford

Title: Multi-armed bandits with uncertainty

Abstract: Making good decisions based on estimates is difficult, but of clear importance in many applications. This is particularly the case when the decisions made will affect the information available in the future. Formally, this means that the filtration of our problem is not fixed in advance, but depends on the control used. We will consider the 'simplest' problem of this type, a multi-armed bandit problem, while taking account of uncertainty aversion. We will see that an extension of the classical Gittins' index approach is possible in this framework, despite many dynamic consistency issues.

LOCATION: The seminar will be held on Wednesday, May 28, at 18.00, Aula di Rappresentanza, Dept. of Mathematics, Milano University, Via C. Saldini 50, Milano. A light reception will take place at 17.45.
