DRSoRec: Dual-Rectification of Social Networks for Recommendation

AAAI 2026technical

Leveraging social homophily to enhance user preference modeling, social recommendation has become a cornerstone of modern recommender systems. However, the raw social network contains inherent unreliability as it teems with noise---misclicks, bot-generated and transient ties---while many meaningful

FairTCD: Dual-Teacher Temporal Contrastive Distillation for Twofold Fair Dynamic Graph Embedding

IJCAI 2026

Fair dynamic graph embedding is crucial for real-world systems, such as recommendation and social networks. Prior studies impose a single-axis fairness formulation, treating attribute and structural bias as separable artifacts. This overlooks their coupling relationship, under which debiasing along

A Multi-Focus-Driven Multi-Branch Network for Robust Multimodal Sentiment Analysis

AAAI 2025technical

Multimodal sentiment analysis aims to integrate diverse modalities for precise emotional interpretation. However, external factors such as sensor malfunctions or network issues may disrupt certain modalities. This may lead to missing data, which poses challenges in real-world deployment. Most existi…

Beyond Homophily: Graph Contrastive Learning with Macro-Micro Message Passing

AAAI 2025technical

Graph contrastive learning (GCL) has drawn much research attention for its ability to learn node representations in a self-supervised manner. However, the homophily assumption inherent in GNN encoders limits the direction (macro-level) and the process (micro-level) of message passing in current GCL…

Review-Enhanced Hierarchical Contrastive Learning for Recommendation

AAAI 2024technical

Designed to establish potential relations and distill high-order representations, graph-based recommendation systems continue to reveal promising results by jointly modeling ratings and reviews. However, existing studies capture simple review relations, failing to (1) completely explore hidden conne…
