New method integrates aleatoric and epistemic uncertainties for deep learning

Researchers have developed a new method to jointly quantify aleatoric and epistemic uncertainties in deep learning models, particularly for high-dimensional output spaces. This approach approximates the joint uncertainty using a low-rank plus diagonal covariance structure, which is computationally more efficient than full covariance matrices. The proposed method integrates both types of uncertainty into a unified second-order distribution, enabling more robust downstream analyses such as sampling and log-likelihood evaluation. It has demonstrated superior uncertainty quantification in tasks including image inpainting, colorization, optical flow, and depth estimation. AI
