A new paper analyzes how self-supervised learning (SSL) methods for vision impact semantic image retrieval systems. The research found that the geometric properties of the learned representations, specifically their isotropy and purity, significantly affect the performance of approximate nearest neighbor (ANN) indexing. Highly anisotropic and skewed representations can degrade search performance, even if they show high accuracy in other tasks. AI
