Understanding Community Bias Amplification in Graph Representation Learning

no code implementations8 Dec 2023 Shengzhong Zhang, Wenjie Yang, Yimin Zhang, Hongwei Zhang, Divin Yan, Zengfeng Huang

In this work, we discover a phenomenon of community bias amplification in graph representation learning, which refers to the exacerbation of performance bias between different classes by graph representation learning.

StructComp: Substituting propagation with Structural Compression in Training Graph Contrastive Learning

1 code implementation8 Dec 2023 Shengzhong Zhang, Wenjie Yang, Xinyuan Cao, Hongwei Zhang, Zengfeng Huang

This allows the encoder not to perform any message passing during the training stage, and significantly reduces the number of sample pairs in the contrastive loss.

Exploring the Semi-supervised Video Object Segmentation Problem from a Cyclic Perspective

1 code implementation2 Nov 2021 Yuxi Li, Ning Xu, Wenjie Yang, John See, Weiyao Lin

We conduct comprehensive comparison and detailed analysis on challenging benchmarks of DAVIS16, DAVIS17 and Youtube-VOS, demonstrating that the cyclic mechanism is helpful to enhance segmentation quality, improve the robustness of VOS systems, and further provide qualitative comparison and interpretation on how different VOS algorithms work.

Rethinking of Pedestrian Attribute Recognition: Realistic Datasets with Efficient Method

2 code implementations25 May 2020 Jian Jia, Houjing Huang, Wenjie Yang, Xiaotang Chen, Kaiqi Huang

Despite various methods are proposed to make progress in pedestrian attribute recognition, a crucial problem on existing datasets is often neglected, namely, a large number of identical pedestrian identities in train and test set, which is not consistent with practical application.
