Disentangling, Amplifying, and Debiasing: Learning Disentangled Representations for Fair Graph Neural Networks

AAAI 2025technical

Graph Neural Networks (GNNs) have become essential tools for graph representation learning in various domains, such as social media and healthcare. However, they often suffer from fairness issues due to inherent biases in node attributes and graph structure, leading to unfair predictions. To address…

SVD-AE: Simple Autoencoders for Collaborative Filtering

IJCAI 2024poster

Collaborative filtering (CF) methods for recommendation systems have been extensively researched, ranging from matrix factorization and autoencoder-based to graph filtering-based methods. Recently, lightweight methods that require almost no training have been recently proposed to reduce overall comp…
