Rich user behavior data has been proven to be of great value for recommendation systems. Modeling lifelong in the retrieval stage explore long-term preference and obtain comprehensive results is crucial. Existing modeling methods cannot applied because they extract target-relevant items through coupling between target item. Moreover, current fail precisely capture interests when length sequence increases further. That leads a gap ability models model data. In this paper, we propose concept...
With the rise of e-commerce and short videos, online recommender systems that can capture users' interests update new items in real-time play an increasingly important role. In both offline recommendation, cold-start problem due to interaction sparsity has been affecting recommendation effect items, which is also known as long-tail item distribution. Many scheme based on fine-tuning or knowledge transferring shows excellent performance recommendation. Yet, these schemes are infeasible for...
