Can Single-Pass Contrastive Learning Work for Both Homophilic and Heterophilic Graph?

1 code implementation20 Nov 2022 Haonan Wang, Jieyu Zhang, Qi Zhu, Wei Huang

To answer this, we analyze the concentration property of features obtained by neighborhood aggregation on both homophilic and heterophilic graphs, introduce the single-pass graph contrastive learning loss based on the property, and provide performance guarantees of the minimizer of the loss on downstream tasks.

UCTransNet: Rethinking the Skip Connections in U-Net from a Channel-wise Perspective with Transformer

2 code implementations9 Sep 2021 Haonan Wang, Peng Cao, Jiaqi Wang, Osmar R. Zaiane

Specifically, the CTrans module is an alternate of the U-Net skip connections, which consists of a sub-module to conduct the multi-scale Channel Cross fusion with Transformer (named CCT) and a sub-module Channel-wise Cross-Attention (named CCA) to guide the fused multi-scale channel-wise information to effectively connect to the decoder features for eliminating the ambiguity.
