Projected GAN

Discriminator の改善手法.

Feature Projectors

実画像、生成画像のDiscriminator の入力空間に、変換する Feature Projectors $\{ P_{l} \}$ を導入する.

目的関数

$\displaystyle \min_{G}\ \max_{\{ D_{l} \}} \displaystyle \sum_{l\ \in\ L} \left( E_{x} \left[ \log\ D_{l} (P_{l} (x)) \right]\ +\ E_{z} \left[ \log\ (1\ -\ D_{l} (P_{l} (G(z))))\right] \right)$

Multi-Scale Discriminators

Random Projections

Cross-Channel Mixing / CCM

Cross-Scale Mixing / CSM

Pretrained Feature Networks
