Proposes Social-like Self-Attention (SSA), with Dynamic Structured Interaction and Discriminative Pillar Verification modules inspired by social network theory, plugged into transformer VQA and REC models to improve visual reasoning.

Problem

Self-attention in transformers suffers from rank collapse and representation degradation with depth, causing redundant aggregation and homogenized features in visual reasoning tasks like VQA and REC.

Approach

Borrows structural hole and degree centrality concepts from social network theory to make SA interactions structured via a learned binary mask over the interaction matrix, and re-weights regions by a learned "pillar" score derived from their focus and transitivity, yielding two plug-and-play modules.
