NettetWe develop likelihood-free inference methods and highlight hypothesis testing as a principle for learning in implicit generative models, using which we are able to derive the objective function used by GANs, and many other related objectives. The testing viewpoint directs our focus to the general problem of density ratio estimation. Nettet前言（Introduction） 人工智能生成内容（AI Generated Content，AIGC）近年来成为了非常前沿的一个研究方向，生成模型目前有四个分支，分别是生成对抗网 …
