Abstract Most link prediction models rely too much on the known link information while mining node similarity. However, the number of the known observed links is small in the real world. To improve the robustness of the model, it is crucial to decouple the dependence of the model on the link information and mine the underlying features of nodes. In this paper, a link prediction model based on adversarial graph convolutional network is proposed with the consideration of the potential relationship between node features and links. Firstly, the similarity metric between nodes is utilized to fill in some unknown links in the adjacency matrix to alleviate the influence of link sparsity on the graph convolution model. Then, the adversarial network is employed to deeply mine the underlying connections between node features and links to reduce the dependence of the model on links. Experiments on real datasets show that the proposed model achieves better performance on link prediction problem and the performance remains relatively stable under link sparsity. Moreover, the proposed model is applicable to large-scale datasets.
