基于自适应双向信息流的序列推荐方法
Sequential Recommendation Method Based on Adaptive Bidirectional Information Flow
摘要
Abstract
To address the challenges of inefficient information fusion and noise interference in sequential recommen-dation,a novel method based on an adaptive bidirectional information flow was proposed.Built upon a dual-path encoder architecture,a hierarchical history summarization module was integrated to distill long-term user prefer-ences,and dynamic frequency-domain filtering was introduced to suppress data noise.The approach fully consid-ered the dependency and interactivity between past and future information by employing an adaptive bidirectional information flow mechanism.This mechanism dynamically adjusted fusion weights via uncertainty perception,enab-ling a precise characterization of the evolution of user preferences.To validate its effectiveness,experiments were conducted on four public datasets including Beauty,Sports,Yelp,and ML1M.And a comparative analysis was performed against 10 mainstream methods.The experimental results demonstrated that the proposed method outper-formed the baseline models in three key metrics:NDCG,HR,and MRR.Compared to three leading baseline mod-els of FMLP-Rec,DualRec,and Oracle4Rec,the proposed method's HR@20 reached 0.652 0 and 0.913 3 on the Beauty and Yelp datasets,which was 2.08 percentage points and 2.89 percentage points higher than their average performance,respectively.Furthermore,its NDCG@20 on the Beauty and Yelp datasets reached 0.394 4 and 0.564 5,outperforming the average of the three baselines by 2.67 percentage points and 2.72 percentage points,respectively.关键词
