Abstract：Most clustering methods mainly focus on single-view data, while the research on multi-view clustering remains relatively under-explored. Existing multi-view clustering methods often emphasize learning inter-view information while neglecting the thorough exploitation of intra-view information. In this paper, a contrastive collaborative multi-view attribute graph clustering based on adaptive structure enhancement(ACCMVC) is proposed. First, an adaptive structure enhancement strategy is designed to generate edge weights by combining node importance and the complex relationships among node features. These edge weights are applied to construct new adjacency matrices for the views, and thereby structure-enhanced graphs are generated. Second, edge weights are introduced into neighborhood contrastive learning. Intra-view enhanced neighborhood contrastive learning is applied to views and their structure-enhanced graphs, while inter-view enhanced neighborhood contrastive learning is utilized among multiple views. Finally, considering the varying view importance, an attention mechanism is introduced to calculate the weight of each view for effective fusion. Experiments on multiple datasets demonstrate that ACCMVC achieves superior clustering performance.
