新框架揭示视觉 Transformer 如何编码几何信息

研究人员开发了一个新框架,用于分析自监督视觉 Transformer (ViTs) 如何编码几何信息。通过使用奇异值分解 (SVD) 来检查线性探针的权重,他们发现预训练目标显著影响特征编码。具体来说,DINOv2 对齐空间特征以便于提取,而掩码自编码器 (MAE) 则分散这些信号,需要更广泛的上下文。研究还表明,几何表示具有高度可压缩性,并且几何精度在中间层达到峰值,然后转移到语义抽象。 AI

影响 为视觉 Transformer 的特征选择和解码器设计提供了见解。

    Understanding Geometric Representations in Self-Supervised Vision Transformers via Subspace Intervention

    We introduce a controlled subspace intervention framework to investigate how self-supervised Vision Transformers (ViTs) encode dense geometric information. While linear probing is widely used to assess geometric representations, it treats features as a black box, failing to disen…
