Disentanglement is defined as the problem of learninga representation that can separate the distinct, informativefactors of variations of data. Learning such a representa-tion may be critical for developing explainable and human-controllable Deep Generative Models (DGMs) in artificialintelligence. However, disentanglement in GANs is not a triv-ial task, as the absence of sample likelihood and posteriorinference for latent variables seems to prohibit the forwardstep. Inspired by contrastive learning (CL), this paper, froma new perspective, proposes contrastive disentanglement ingenerative adversarial networks (CD-GAN). It aims at dis-entangling the factors of inter-class variation of visual datathrough contrasting image features, since the same factorvalues produce images in the same class. More importantly,we probe a novel way to make use of limited amount ofsupervision to the largest extent, to promote inter-class dis-entanglement performance. Extensive experimental resultson many well-known datasets demonstrate the efficacy ofCD-GAN for disentangling inter-class variation.

本文从对比学习的角度提出了一种新的对抗生成网络（CD-GAN）来解决因潜变量的后验推断和缺乏样本似然性而难以实现的生成模型因果解释的问题，它通过对比图像特征来实现对数据中不同类之间可辨别属性的提取，并通过仅有的有限监督来提高模型的性能。实验结果表明了该模型在多个数据集上对数据进行高效的可解释性特征提取。
