Conformal Prediction Sets for Instance Segmentation

arXiv:2602.10045v2 Announce Type: replace-cross Abstract: Current instance segmentation models achieve high performance on average predictions, but lack principled uncertainty quantification: their outputs are not calibrated, and there is no guarantee that a predicted mask is close to the ground truth. To address this limitation, we introduce a conformal prediction algorithm to generate adaptive confidence sets for instance segmentation. Given an image and a pixel coordinate query, our algorithm generates a confidence set of instance predictions for that pixel, with a provable guarantee for th

Why this matters
Why now

The increasing deployment of AI in critical applications demands robust uncertainty quantification, and advancements in conformal prediction methods for complex tasks like instance segmentation are now maturing.

Why it’s important

This development addresses a fundamental limitation in current AI models by providing provable guarantees of prediction accuracy, crucial for building trust and enabling reliable deployment in sensitive domains.

What changes

AI systems can now offer explicit and guaranteed bounds on the confidence of their instance segmentation outputs, moving beyond average performance metrics to more auditable and reliable predictions.
