In this work, we argue that the pre-trained GAN generator can be considered as a learned multi-scale loss. Training with it can bring highly competitive hierarchical and disentangled visual features, which we call Generative Hierarchical Features (GH-Feat). We further show that GH-Feat facilitates a wide range of not only generative but more importantly discriminative tasks, including face verification, landmark detection, layout prediction, transfer learning, style mixing, image editing, etc.
