Overview

Experimental evaluation demonstrates enhanced multimodal sequential recommendation accuracy across e-commerce domains, indicating the effectiveness of cross-modal alignment and temporal gating.

Key Points

To develop a multimodal sequential recommendation framework that resolves feature-space heterogeneity, modality-specific noise, and evolving temporal user preferences.
Constructed a cross-modal alignment mixture-of-experts architecture using dedicated and common experts to balance modality-specific and shared representations.
Implemented a hierarchical time-aware routing module driven by intervals, spans, and periodic encodings, integrated with sequential contrastive learning.
Evaluated performance against representative sequential and multimodal recommendation baselines across game, beauty, and toy benchmark datasets.
Consistently outperformed baseline models on NDCG@5, NDCG@10, MRR@5, and MRR@10 across all evaluated e-commerce domains.
Ablation experiments confirmed significant performance gains derived from both the cross-modal alignment module and the temporal gating mechanism.
