co-attention routing

Co-attention routing is a dynamic computational mechanism in multimodal deep learning that adaptively directs information flow across different cross-modal attention pathways based on the input data. Unlike static multimodal interaction layers or unimodal routing schemes that process features uniformly, co-attention routing evaluates relationships between multiple modalities, such as text and images, and dynamically selects or weights candidate co-attention operations conditioned on the specific input sample. This input-dependent pathway selection enables neural networks to capture subtle cross-modal alignments, incongruities, and varying granularities of multimodal interaction with greater adaptability and efficiency.
