SpeedCP: Fast Kernel-based Conditional Conformal Prediction

arXiv:2509.24100v2 Announce Type: replace-cross Abstract: Conformal prediction provides distribution-free prediction sets with finite-sample conditional guarantees. We build upon the RKHS-based framework of Gibbs et al. (2023), which leverages families of covariate shifts to provide approximate conditional conformal prediction intervals, an approach with strong theoretical promise, but with prohibitive computational cost. To bridge this gap, we develop a stable and efficient algorithm that computes the full solution path of the regularized RKHS conformal optimization problem, at essentially th

Why this matters
Why now

The increasing demand for reliable and robust AI systems across various applications is driving the development of more efficient and scalable methods for uncertainty quantification.

Why it’s important

Improved computational efficiency for conditional conformal prediction (CCP) allows for broader adoption of rigorous uncertainty guarantees in AI, crucial for high-stakes decisions.

What changes

The ability to compute full solution paths for RKHS-based CCP more quickly will make these advanced uncertainty quantification techniques practical for a wider range of machine learning models and data scales.
