GANの評価

GANの学習過程において、生成される画像の質や、多様性を評価する。 評価尺度はFrechet Inception Distance(FID)とInception Score(FID)

Frechet Inception Distance:https://arxiv.org/abs/1706.08500

Inception Score:http://papers.nips.cc/paper/6124-improved-techniques-for-training-gans

GAN.py、ACGAN.py、WGAN.pyにてモデルの構造、loss、学習ほうなどを定義

fid_score.pyでFIDの、inception_score.pyでISの計算法を定義

inception.pyではFIDやISを計算するときに用いる学習済みの分類モデル(Inceptionモデル)を定義

main.pyにてモデルの学習を実行、GAN.pyでは学習時にFID、ISを保存し可視化する
