Graph Fairness Learning under Distribution Shifts

no code implementations30 Jan 2024 Yibo Li, Xiao Wang, Yujie Xing, Shaohua Fan, Ruijia Wang, Yaoqi Liu, Chuan Shi

Recently, there has been an increasing interest in ensuring fairness on GNNs, but all of them are under the assumption that the training and testing data are under the same distribution, i. e., training data and testing data are from the same graph.

Uncovering the Structural Fairness in Graph Contrastive Learning

1 code implementation6 Oct 2022 Ruijia Wang, Xiao Wang, Chuan Shi, Le Song

Recent studies show that graph convolutional network (GCN) often performs worse for low-degree nodes, exhibiting the so-called structural unfairness for graphs with long-tailed degree distributions prevalent in the real world.

Combining Deep Learning with Physics Based Features in Explosion-Earthquake Discrimination

no code implementations12 Mar 2022 Qingkai Kong, Ruijia Wang, William R. Walter, Moira Pyle, Keith Koper, Brandon Schmandt

This paper combines the power of deep-learning with the generalizability of physics-based features, to present an advanced method for seismic discrimination between earthquakes and explosions.

Multi-Component Graph Convolutional Collaborative Filtering

A Fast Proximal Point Method for Computing Exact Wasserstein Distance

1 code implementation12 Feb 2018 Yujia Xie, Xiangfeng Wang, Ruijia Wang, Hongyuan Zha

However, as we will demonstrate, regularized variations with large regularization parameter will degradate the performance in several important machine learning applications, and small regularization parameter will fail due to numerical stability issues with existing algorithms.
