Deep graph clustering, which aims to reveal the underlying graph structure
and divide the nodes into different groups, has attracted intensive attention
in recent years. However, we observe that, in the process of node encoding,
existing methods suffer from representation collapse which tends to map all
data into the same representation. Consequently, the discriminative capability
of the node representation is limited, leading to unsatisfied clustering
performance. To address this issue, we propose a novel self-supervised deep
graph clustering method termed Dual Correlation Reduction Network (DCRN) by
reducing information correlation in a dual manner. Specifically, in our method,
we first design a siamese network to encode samples. Then by forcing the
cross-view sample correlation matrix and cross-view feature correlation matrix
to approximate two identity matrices, respectively, we reduce the information
correlation in the dual-level, thus improving the discriminative capability of
the resulting features. Moreover, in order to alleviate representation collapse
caused by over-smoothing in GCN, we introduce a propagation regularization term
to enable the network to gain long-distance information with the shallow
network structure. Extensive experimental results on six benchmark datasets
demonstrate the effectiveness of the proposed DCRN against the existing
state-of-the-art methods.

提出了一种名为 Dual Correlation Reduction Network（DCRN）的方法，该方法采用双重相关性降低的策略来减少节点编码过程中的表征崩溃现象，同时通过 GCN 中引入传播正则化项来缓解过度平滑造成的表征崩溃现象，实验表明该方法在六个基准数据集上相比于现有最先进算法表现更好。
