Segment Anything with Robust Uncertainty-Accuracy Correlation

Hongyou Zhou, Ling Shao, Marc Toussaint, Zihan Ye

RUAC adds a lightweight uncertainty head to SAM and trains it with joint style-deformation attacks plus alignment to keep uncertainty tied to pixel errors under domain shifts.

✓ Portable graph bundle live · download bundle · merged state

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Across 23 zero-shot domains, RUAC improves segmentation quality and yields more faithful uncertainty with stronger uncertainty-accuracy correlation.

C2weakest assumption

That out-of-domain variation can be adequately modeled as appearance shifts and non-rigid deformations, and that the collaborative style-deformation attack plus Uncertainty-Accuracy Alignment will produce uncertainty estimates that remain faithful under real-world domain shifts beyond the 23 tested domains.

C3one line summary

RUAC adds an uncertainty head to SAM, trains it via collaborative style-deformation attacks and Uncertainty-Accuracy Alignment, and reports improved segmentation quality plus stronger uncertainty-accuracy correlation across 23 zero-shot domains.
