SPACR introduces a differentiable training framework that aligns model optimization directly with the efficiency goals of Conformal Prediction, eliminating the need for post-hoc adjustments or batch splitting. By jointly optimizing validity and interval tightness within a single pass, the method significantly reduces computational costs while delivering superior coverage-efficiency trade-offs compared to standard approaches. This advancement offers a practical solution for deploying robust uncertainty quantification in production environments where retraining is prohibitive.
SPACR: Single-Pass Adaptive Training of Uncertainty-Aware Conformal Regressors
arXiv:2606.10734v1 Announce Type: new Abstract: Conformal Prediction (CP) provides robust uncertainty guarantees for predictive models, but is typically applied post hoc, which misaligns model training with the conformal goal of producing efficient (i.e, narrow) intervals. We propose SPACR (Single-Pass Adaptive Conformal Regressor), a novel method for directly training uncertainty-aware regressors within a differentiable loss. SPACR jointly optimizes efficiency and validity without batch-splitting or a predefined confidence levels during training. As a result, a single SPACR model yields valid prediction intervals at multiple confidence levels during inference, avoiding the costly retraining required by methods like DOICR. Experiments on diverse datasets show that SPACR consistently gives tighter intervals and better coverage-efficiency trade-offs compared to standard CP and DOICR, while significantly reducing computational costs.
