题目: Diverse Image Generation via Self-Conditioned GANs

摘要:

本文介绍了一个简单但有效的无监督方法,以产生现实和多样化的图像,并且训练了一个类条件GAN模型,而不使用手动注释的类标签。相反,模型的条件是标签自动聚类在鉴别器的特征空间。集群步骤自动发现不同的模式,并显式地要求生成器覆盖它们。在标准模式基准测试上的实验表明,该方法在寻址模式崩溃时优于其他几种竞争的方法。并且该方法在ImageNet和Places365这样的大规模数据集上也有很好的表现,与以前的方法相比,提高了图像多样性和标准质量指标。

Generative adversarial networks (GANs) have shown significant potential in modeling high dimensional distributions of image data, especially on image-to-image translation tasks. However, due to the complexity of these tasks, state-of-the-art models often contain a tremendous amount of parameters, which results in large model size and long inference time. In this work, we propose a novel method to address this problem by applying knowledge distillation together with distillation of a semantic relation preserving matrix. This matrix, derived from the teacher's feature encoding, helps the student model learn better semantic relations. In contrast to existing compression methods designed for classification tasks, our proposed method adapts well to the image-to-image translation task on GANs. Experiments conducted on 5 different datasets and 3 different pairs of teacher and student models provide strong evidence that our methods achieve impressive results both qualitatively and quantitatively.
