The aim is to enhance music emotion recognition by addressing the limitations of existing unimodal approaches through a multimodal optimization framework.
Developed the MELT framework with modules: BERT-based lyrics semantic encoder, segment temporal encoder, token-level temporal fusion, and emotion mood head.
Conducted end-to-end training by minimizing supervised classification and auxiliary cross-modal contrastive alignment terms.
Evaluated performance on the MoodyLyrics benchmark with a focus on four-class emotion prediction.
MELT achieved 87.6% weighted F1 score for four-class emotion recognition (angry, happy, relaxed, sad).
Outperformed unimodal baselines and other early/late fusion strategies.
Ablation results confirmed the contributions of temporal encoding, gated fusion, and joint optimization on performance.
