Abstract

To address modality heterogeneity, time-varying contributions, and limited semantic abstraction in multimodal sentiment analysis, this paper proposes a three-stage closed-loop fusion model (MIFA) . Specifically, it follows an alignment-regulation-abstraction fusion path that comprises unified semantic alignment, dynamic fusion regulation, and hierarchical semantic abstraction. First, unified semantic alignment expresses heterogeneous modalities in a shared space. Next, contextual gating and channel modulation estimate modality/channel weights and refine representations. Finally, a hierarchical residual abstraction enhances discriminative features, forming an end-to-end closed loop. Experiments on CMU-MOSI and CMU-MOSEI show that MIFA achieves Acc2 of 86.43%/86.03% and F1 of 86.42%/85.81%; Acc7 reaches 45.04%/50.41%, and MAE is 0.689/0.532, outperforming mainstream baselines. These results indicate that MIFA stabilizes cross-modal alignment and adaptively regulates information flow, improves sentiment classification and intensity regression, and offers practical potential for complex multimodal scenarios.
