RARE: Robust Masked Graph Autoencoder

2023 · arXiv (Cornell University)

Masked graph autoencoder (MGAE) has emerged as a promising self-supervised graph pre-training (SGP) paradigm due to its simplicity and effectiveness. However, existing efforts perform the mask-then-reconstruct operation in the raw data space as is done …

Cluster-Guided Contrastive Graph Clustering Network

2023 · Proceedings of the AAAI Conference on Artificial Intelligence

Benefiting from the intrinsic supervision information exploitation capability, contrastive learning has achieved promising performance in the field of deep graph clustering recently. However, we observe that two drawbacks of the positive and negative sample construction …
