A team from Beijing University of Posts and Telecommunications introduced Mixture-of-Top-k Attention (MiTA) at NeurIPS'26. By reframing standard attention as a dynamic Feed-Forward Network with width scaling by sequence length via 'Fast Weights', they established a five-dimensional classification framework. MiTA employs deformable, reusable Top-k experts to balance global context retention with on-demand detail retrieval, offering a unified architectural perspective for understanding long-context costs and reconciling diverse attention mechanisms.

    • Core Insight: Standard attention is mathematically equivalent to an FFN whose hidden layer width dynamically scales with input sequence length.
    • Methodological Innovation: Introduces a five-dimensional 'Fast Weights' framework that unifies linear attention, MoE attention, and other variants under a single organizational logic.
    • Model Performance: The MiTA model utilizes deformable Top-k experts to efficiently retrieve raw details while preserving global semantic context.
