Plug-in Losses for Evidential Deep Learning: A Simplified Framework for Uncertainty Estimation that Includes the Softmax Classifier
Researchers have developed a simplified framework for Evidential Deep Learning (EDL) that makes uncertainty estimation more computationally efficient. This new approach approximates EDL's objective with a plug-in loss evaluated at the Dirichlet mean, which is simpler to implement using standard deep learning tools. The framework includes the standard softmax classifier as a special case and has been validated on the Google Speech Commands dataset, achieving performance comparable to classical EDL. AI
