A Multi-view Graph Contrastive Learning Framework for Cross-Domain Sequential Recommendation

2023

Sequential recommendation methods play an irreplaceable role in recommender systems which can capture the users’ dynamic preferences from the behavior sequences. Despite their success, these works usually suffer from the sparsity problem commonly existed in …

Heterogeneous Graph Transfer Learning for Diversity-enhanced Cross-Domain Sequential Recommendation

2026 · ACM Transactions on Recommender Systems

Cross-domain Sequential Recommendation (CDSR) aims to alleviate the data sparsity problem in recommender systems by leveraging auxiliary information from other domains to better capture users’ sequential preferences. However, existing CDSR methods still face several limitations. …
