New framework reveals how Vision Transformers encode geometry

Researchers have developed a new framework to analyze how self-supervised Vision Transformers (ViTs) encode geometric information. By using Singular Value Decomposition (SVD) to examine the weights of linear probes, they found that pre-training objectives significantly influence feature encoding. Specifically, DINOv2 aligns spatial features for easier extraction, while Masked Autoencoders (MAE) disperse these signals, requiring broader context. The study also revealed that geometric representations are highly compressible and that geometric precision peaks in intermediate layers before shifting to semantic abstraction. AI
