论文摘要
基于自动编码器的深度子空间聚类（DSC）广泛用于计算机视觉，运动分割和图像处理。但是，它在自我表达的矩阵学习过程中遇到了以下三个问题：由于简单的重建损失，第一个对于学习自我表达权重的信息较小；第二个是与样本量相关的自我表达层的构建需要高计算成本。最后一个是现有正规化条款的有限连接性。为了解决这些问题，在本文中，我们提出了一个新颖的模型，名为“自我监督的深度”子空间聚类，并使用熵 - - 核心（S $^{3} $ CE）。具体而言，S $^{3} $ CE利用了自我监督的对比网络，以获得更加繁荣的特征向量。原始数据的局部结构和密集的连通性受益于自我表达层和其他熵 - 标准约束。此外，具有数据增强的新模块旨在帮助S $^{3} $ CE专注于数据的关键信息，并通过光谱聚类来提高正面和负面实例的聚类性能。广泛的实验结果表明，与最先进的方法相比，S $^{3} $ CE的出色性能。
Auto-Encoder based deep subspace clustering (DSC) is widely used in computer vision, motion segmentation and image processing. However, it suffers from the following three issues in the self-expressive matrix learning process: the first one is less useful information for learning self-expressive weights due to the simple reconstruction loss; the second one is that the construction of the self-expression layer associated with the sample size requires high-computational cost; and the last one is the limited connectivity of the existing regularization terms. In order to address these issues, in this paper we propose a novel model named Self-Supervised deep Subspace Clustering with Entropy-norm (S$^{3}$CE). Specifically, S$^{3}$CE exploits a self-supervised contrastive network to gain a more effetive feature vector. The local structure and dense connectivity of the original data benefit from the self-expressive layer and additional entropy-norm constraint. Moreover, a new module with data enhancement is designed to help S$^{3}$CE focus on the key information of data, and improve the clustering performance of positive and negative instances through spectral clustering. Extensive experimental results demonstrate the superior performance of S$^{3}$CE in comparison to the state-of-the-art approaches.
