Enhancing Guidance for Missing Data in Diffusion-Based Sequential Recommendation

ICASSP 2026poster

Contemporary sequential recommendation methods are becoming more complex, shifting from classification to a diffusion-guided generative paradigm. However, the quality of guidance in the form of user information is often compromised by missing data in the observed sequences, leading to suboptimal gen…

AlignMamba: Enhancing Multimodal Mamba with Local and Global Cross-modal Alignment

CVPR 2025poster

Cross-modal alignment is crucial for multimodal representation fusion due to the inherent heterogeneity between modalities. While Transformer-based methods have shown promising results in modeling inter-modal relationships, their quadratic computational complexity limits their applicability to long-…

EMMA: Empowering Multi-modal Mamba with Structural and Hierarchical Alignment

ICLR 2025poster

Mamba-based architectures have shown to be a promising new direction for deep learning models owing to their competitive performance and sub-quadratic deployment speed. However, current Mamba multi-modal large language models (MLLM) are insufficient in extracting visual features, leading to imbalanc…
