Inferring beliefs from Bayes-optimal behavior

I'll discuss a method for inferring a subject's beliefs (in the form of an a priori distribution) from his/her behavior, under the assumption that the behavior is (near-) optimal from a Bayesian perspective. The problem can be cast in a fairly nonparametric way (i.e., we don't have to impose any strong assumptions on the subject's beliefs), and the solution is surprisingly computationally tractable.

Time permitting, I'll also discuss some recent results on maximum-likelihood estimation of a point process neural model, for which some of the mathematics turns out to have a similar flavor.
