New SPOOK method probes vision encoder failures on blank canvases

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a novel method called SPOOK (Sparse Pixel Optimization for Off-Manifold Knowledge) to probe the inner workings of vision encoders. This technique involves making sparse pixel edits on blank canvases, which are then analyzed to see if they can retrieve specific targets within multimodal contrastive and self-supervised visual encoders. The findings indicate that even simple edits on non-semantic inputs can access target semantic basins, revealing a shared off-manifold failure mode in modern vision encoders and suggesting this optimization method as a tool for understanding representation geometry.

    SPOOK: Sparse Pixel Optimization for Off-Manifold Knowledge in Vision Encoders

    arXiv:2610.32835v1 Announce Type: cross Abstract: Modern vision encoders are widely used as semantic representations, but the relationship between embedding similarity and human-visible semantics can become unclear far from the natural-image manifold. We probe this regime in a bl…
