The classical spectral clustering algorithm often involves computationally expensive feature decomposition of the Laplacian matrix, prompting researchers to introduce a deep learning model into the spectral clustering algorithm. Nonetheless, the existing methods possess certain limitations. The existing clustering model neglects the information on the correlation degree between nodes, which leads to inaccurate clustering results. Additionally, when the number of nodes in the graph neural network changes, the whole graph requires updating, leading to extensive storage space consumption. By combining the attention mechanism with the improved architecture of graph convolutional neural networks, this paper proposes a spectral clustering method based on the attention and graph convolutional neural network to address these issues. The proposed method mainly utilizes the attention mechanism to guide node clustering, following which it establishes the corresponding target. The corresponding cluster allocation, when the target is optimal, is calculated by training the neural network. Attention information and topological information are used to guide the graph reconstruction process, thereby improving the accuracy of reconstruction. Experimental results reveal that the proposed method exhibits excellent performance in graph classification, graph clustering, and graph reconstruction tasks.
