Intrinsic Modality Bias Identified
The research provides strong evidence that MLLMs, like LLaVA-1.5-7B and Qwen2.5-VL, exhibit an inherent text bias due to a misalignment in the attention key space. This bias is not merely a result of external data factors but an internal architectural limitation where visual key vectors are out-of-distribution compared to the text key space.
Attention Key-Space Analysis
To validate the hypothesis, key vectors were extracted from decoder layers of LLaVA and Qwen2.5-VL. Qualitative (t-SNE) and quantitative (Jensen-Shannon divergence, MMD) analyses revealed distinct subspaces for visual and textual keys, confirming a statistically significant inter-modal divergence far exceeding intra-modal variations.
