Vision Transformers learn spatial hierarchy mirroring primate visual cortex

Researchers have investigated how Vision Transformers (ViTs) encode spatial information without explicit spatial supervision during pretraining. By probing a ViT-B/16 model, they found that boundary structure is decodable by layer 5-6, while depth information, requiring more global cues, becomes decodable two to three layers later. This learned spatial hierarchy within the ViT mirrors the progression observed in the primate visual cortex. AI

IMPACT Reveals how classification-trained ViTs develop an internal spatial hierarchy, potentially informing future model architectures.

    From Edges to Depth: Probing the Spatial Hierarchy in Vision Transformers

    arXiv:2604.23452v1 Announce Type: new Abstract: Vision Transformers trained only on image classification routinely transfer to tasks that demand spatial understanding, yet they receive no spatial supervision during pretraining. We ask where and how robustly such structure is enco…
