Research Paper Overview
Post-Hoc Split-Point Self-Consistency Verification for Efficient, Unified Quantification of Aleatoric and Epistemic Uncertainty in Deep Learning
Summary
This paper proposes a post-hoc single-forward-pass framework that jointly quantifies aleatoric and epistemic uncertainty in pretrained deep learning models without retraining. It introduces Split-Point Analysis (SPA) to decompose predictive residuals and defines a Self-consistency Discrepancy Score (SDS) for fine-grained epistemic uncertainty estimation. The method improves prediction intervals for regression and calibrates classification probabilities, matching or exceeding state-of-the-art uncertainty quantification methods with minimal overhead.
