DistMatch: Adaptive Binning via Distribution Matching for Robust Sequential Conformal Prediction
arXiv:2606.00690v1 Announce Type: new Abstract: Sequential conformal prediction (CP) provides valid uncertainty quantification under the assumption of residual exchangeability. However, this assumption is often violated in real-world time series due to temporal dependencies and distributional shifts. While recent methods attempt to approximate exchangeability through reweighting, identifying optimal weights remains an open challenge. To address this limitation, we propose DistMatch, a binning-based method that recursively partitions residuals within a binary tree using the Kolmogorov-Smirnov (
The increasing complexity and real-world deployment of AI models, especially in sequential data, demand more robust and reliable uncertainty quantification methods.
Improved sequential conformal prediction enhances the trustworthiness and safety of AI systems operating with time-series data, crucial for areas like financial forecasting, autonomous systems, and medical monitoring.
This research offers a new method to address violations of exchangeability in sequential conformal prediction, potentially leading to more accurate and reliable confidence intervals for AI predictions where temporal dependencies exist.
