New method quantifies uncertainty in black-box vision models

By PulseAugur Editorial · [1 sources] ·

Researchers have developed SpatialUQ, a novel post-hoc uncertainty quantification method for black-box vision models, particularly in clinical settings. This method measures the divergence between a global prediction and predictions from fixed spatial crops, assuming that trustworthy predictions are spatially consistent. SpatialUQ demonstrated superior performance in detecting failures and calibration compared to MC Dropout on the NIH ChestX-ray14 dataset, while requiring significantly less computation. The technique shows promise for identifying diffuse findings but may be less reliable for small focal lesions. AI

IMPACT This method could improve the reliability and trustworthiness of AI models in critical applications like medical diagnostics.

    SpatialUQ: Post-Hoc Uncertainty Quantification from Spatial Consistency in Black-Box Vision Models

    arXiv:2610.09498v1 Announce Type: cross Abstract: Clinical vision models are often deployed as frozen black boxes with no access to internals, retraining, or ground truth at inference time. We introduce \textbf{SpatialUQ}, a post-hoc uncertainty method using only output probabili…
