- Abstract:
-
Addressing the challenges of inefficient information fusion and noise interference in sequential recommendation, 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 preferences, and dynamic frequency-domain filtering was introduced to suppress data noise. The approach fully considered the dependency and interactivity between past and future information by employing an adaptive bidirectional information flow mechanism. This mechanism dynamically adjusts fusion weights via uncertainty perception, enabling 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 outperformed the baseline models in three key metrics: NDCG, HR, and MRR. Compared to the three leading baseline models of FMLP-Rec, DualRec, and OracleRec, 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.
