Dear all, 

Our upcoming AM seminar is held next Wednesday 20 September at 1pm in F07 Carslaw
Lecture Theatre 373.  Our speaker is Matthew Tam (University of Melbourne).

Title: Splitting algorithms for training GANs 

Abstract: Generative adversarial networks (GANs) are an approach to fitting generative
models over complex structured spaces.  Within this framework, the fitting problem is
posed as a zero-sum game between two competing neural networks which are trained
simultaneously.  Mathematically, this problem takes the form of a saddle-point problem;
a well-known example of the type of problem where the usual (stochastic) gradient
descent-type approaches used for training neural networks fail.  In this talk, we
rectify this shortcoming by proposing a new method for training GANs that has: (i) a
sounds theoretical foundation, and (ii) does not increase the algorithm’s per iteration
complexity (as compared to gradient descent).  The theoretical analysis is performed
within the framework of monotone operator splitting.
