Suppression Method of Mode Collapse in Generative Adversarial Nets
Shinya Hidai, Hidehiro Nakano, Arata Miyauchi (Tokyo City Univ.) CCS2017-33
Abstract (in Japanese) (See Japanese page) 
(in English) Generative Adversarial Nets (GAN) is constituted by two neural networks, Generator and Discrminator. Generator creates data, and Discriminator estimates data that came from training data. The purpose of GAN is to let Generator estimate the probability distribution of training data. There is a problem in the GAN that the Generator can only estimate the local maximum of a part of the probability distribution of the training data, which is known as Mode Collapse. In this paper, in order to suppress the occurrence of Mode Collapse, we propose a method to change loss function of Generator to an expression with a large gradient even when learning of Generator proceeds. We verify this proposed method by estimating the Gaussian mixture model in two dimensional space.
