①Progressive Growing of GANs
●論文:Progressive Growing of GANs for Improved Quality,
Stability, and Variation
https://arxiv.org/abs/1710.10196
目的:高画質・安定・多様な画像生成
手法:GeneratorとDiscriminatorに
徐々に高画質な層を追加してく
Goodfellow: probably the highest quality images so far

17. Bread Company
②Spectral Normalization for GANs
●論文:Spectral Normalization for Generative Adversarial Networks
https://arxiv.org/abs/1802.05957
目的:Discriminatorの学習の安定化
手法:Spectral Normで重みを正規化する
Goodfellow:got GANs working on lots of classes, which has been hard

24. Bread Company
③cGANs with Projection Discriminator
●論文:cGANs with Projection Discriminator
https://arxiv.org/abs/1802.05637
目的:安定した画像生成
多様な画像生成
カテゴリーを連続的に移動や高画質化も可能にしたい
手法:cGANを改良して、最後にyとの内積をとる
Goodfellow:from the same lab as #2, both techniques work well
together, overall give very good results with 1000 classes

⑤ Are GANs Created Equal?
●論文:Are GANs Created Equal? A Large-Scale Study
https://arxiv.org/abs/1711.10337
目的:そこまでGAN(original)とX-GANの代わりはない説
FIDのminだけを見ることをへの疑問
その他色々GANの検証
手法:GANs (MM,LS,W,W-GP,BE)-GAN
Metric: FID,InceptionScore,F1
Goodfellow:A big empirical study showing the importance of good
rigorous empirical work and how a lot of the GAN variants don't
seem to actually offer improvements in practice

59. Bread Company
⑥Wasserstein GANs - GP
●論文:Improved Training of Wasserstein GANs
https://arxiv.org/abs/1704.00028
目的:Wasserstein GANの安定化
手法:WGANに勾配が1になるようにペナルティを化す
Goodfellow:probably the most popular GAN variant today and seems
to be pretty good in my opinion. Caveat: the baseline GAN variants
should not perform nearly as badly as this paper claims, especially
the text one
