New research examines uncertainty in image segmentation models

A new paper on arXiv explores uncertainty quantification (UQ) in image segmentation, a critical area for safety-sensitive applications. The research investigates the interaction between aleatoric uncertainty (data-related) and epistemic uncertainty (model-related), noting significant entanglement between them that can reduce interpretability. The study proposes a metric to quantify this entanglement and finds that ensembles generally perform better with lower entanglement, while softmax models show varied results depending on the dataset and calibration task.
