Beyond Item Order: Temporal Gap Tokenization for Generative Recommendation with Semantic IDs

Chengkai Huang, Tianqi Gao, Hongtao Huang +2

Semantic-ID-based generative recommendation has recently emerged as a scalable paradigm for sequential recommendation, where each item is represented by a compact sequence of discr…

Generative Chain of Behavior for User Trajectory Prediction

Chengkai Huang, Xiaodi Chen, Hongtao Huang +2

Modeling long-term user behavior trajectories is essential for understanding evolving preferences and enabling proactive recommendations. However, most sequential recommenders focu…

Listwise Preference Diffusion Optimization for User Behavior Trajectories Prediction

Hongtao Huang, Chengkai Huang, Junda Wu +3

Forecasting multi-step user behavior trajectories requires reasoning over structured preferences across future actions, a challenge overlooked by traditional sequential recommendat…

Gaussian Mixture Flow Matching with Domain Alignment for Multi-Domain Sequential Recommendation

Xiaoxin Ye, Chengkai Huang, Hongtao Huang +1

Users increasingly interact with content across multiple domains, resulting in sequential behaviors marked by frequent and complex transitions. While Cross-Domain Sequential Recomm…

Beyond Negative Transfer: Disentangled Preference-Guided Diffusion for Cross-Domain Sequential Recommendation

Xiaoxin Ye, Chengkai Huang, Hongtao Huang +1

Cross-Domain Sequential Recommendation (CDSR) leverages user behaviors across domains to enhance recommendation quality. However, naive aggregation of sequential signals can introd…

Flexiffusion: Training-Free Segment-Wise Neural Architecture Search for Efficient Diffusion Models

Hongtao Huang, Xiaojun Chang, Lina Yao

Diffusion models (DMs) are powerful generative models capable of producing high-fidelity images but are constrained by high computational costs due to iterative multi-step inferenc…
