Greeting, This week we will have Olivier D. tell us about sum-product networks and his recent contributions to their theoretic development. This work will be appearing at the upcoming NIPS. When: Wednesday Nov. 9th. 14h00 Where: LISA LAB (AA3256) Title: On Sum-Product Networks Abstract: I will explain what are sum-product networks, why they can be useful, and why we care about deep ones. I will provide theoretical results on the expressive power of deep sum-product networks, showing they are able to represent some functions (exponentially) more compactly than their shallow counterpart. These results contribute to motivate recent research involving learning of deep sum-product networks, and more generally motivate research in Deep Learning. This is joint work with Yoshua.
