Further on, it will be interesting to see how new GAN techniques apply to this problem. It is hard to believe, only in 6 months, new ideas are already piling up. Trying stuff like StackGAN, better GAN models like WGAN and LSGAN(Loss Sensitive GAN), and other domain transfer network like DiscoGAN with it, could be enormously fun. Acknowledgements

Loss-Sensitive Generative Adversarial Network (LS-GAN). Speci cally, it trains a loss function to distinguish between real and fake samples by designated margins, while learning a generator alternately to produce realistic samples by minimizing their losses. The LS-GAN further regu-

In build_LSGAN_graph, we should define the loss function for the generator and the discriminator. Another difference is that we do not do weight clipping in LS-GAN, so clipped_D_parames is no longer needed. Instead, we use weight decay which is mathematically equivalent to …

Least Squares GAN(以下LSGAN)は正解ラベルに対する二乗誤差を用いる学習手法を提案しています。 論文の生成画像例を見ると、データセットをそのまま貼り付けているかのようなリアルな画像が生成されていたので興味を持ちました。 実装は非常に簡単です。

Even more than that, GazeGAN uses label smoothing on top of the LSGAN loss: while the discriminator aims to output 1 on real examples and 0 on refined synthetic images, the generator smoothes its target to 0.9, getting the loss function.
