Title: RBMs for the analysis of neural data

Abstract: In this talk, I will illustrate some of the work done during my PhD about using restricted Boltzmann machines to fit neuronal spike trains and analyse their statistics. I will introduce the general area of energy-based models of neural activity, and show how RBMs can attain excellent fits. Additionally, they can teach us about the presence of "modes" in the activity of a network, provide a nonparametric measure of distance between statistics, and exhibit a form of criticality in the same way as maximum-entropy models.
