Behavior Tokens Speak Louder: Disentangled Explainable Recommendation with Behavior Vocabulary

AAAI 2026technical

Recent advances in explainable recommendation have explored the integration of language models to analyze natural language rationales for user–item interactions. Despite their potential, existing methods often rely on ID-based representations that obscure semantic meaning and impose structural const

Improving Temporal Link Prediction via Temporal Walk Matrix Projection

NeurIPS 2024poster

Temporal link prediction, aiming at predicting future interactions among entities based on historical interactions, is crucial for a series of real-world applications. Although previous methods have demonstrated the importance of relative encodings for effective temporal link prediction, computation…

Continuous-Time Graph Learning for Cascade Popularity Prediction

IJCAI 2023poster

Information propagation on social networks could be modeled as cascades, and many efforts have been made to predict the future popularity of cascades. However, most of the existing research treats a cascade as an individual sequence. Actually, the cascades might be correlated with each other due to…

Generic and Dynamic Graph Representation Learning for Crowd Flow Modeling

AAAI 2023technical

Many deep spatio-temporal learning methods have been proposed for crowd flow modeling in recent years. However, most of them focus on designing a spatial and temporal convolution mechanism to aggregate information from nearby nodes and historical observations for a pre-defined prediction task. Diffe…

Predicting Temporal Sets with Simplified Fully Connected Networks

AAAI 2023technical

Given a sequence of sets, where each set contains an arbitrary number of elements, temporal sets prediction aims to predict which elements will appear in the subsequent set. Existing methods for temporal sets prediction are developed on sophisticated components (e.g., recurrent neural networks, atte…
