Cluster Frequency Conformal Prediction for Local Coverage

arXiv:2605.24872v1 Announce Type: new Abstract: Conformal prediction provides distribution-free coverage guarantees, but in many-class classification it may still under-cover specific classes or subpopulations, preventing safe deployment in high-stakes applications. We propose Cluster Frequency Conformal Prediction (CFCP), a plug-in framework that adapts conformal prediction to local structure in a learned representation space. CFCP clusters learned embeddings, estimates cluster-level label-frequency distributions from calibration data, and for each test point constructs a sample-specific prob

Why this matters
Why now

The increasing deployment of AI in high-stakes applications necessitates robust, auditable methods for ensuring model reliability and safety, driving innovation in areas like conformal prediction.

Why it’s important

This development enhances the trustworthiness and ethical deployment of AI systems, particularly in sensitive areas where misclassification has significant consequences.

What changes

AI models can now offer more granular and reliable uncertainty estimates, ensuring better coverage for specific classes and subpopulations, which was a critical limitation of previous conformal prediction methods.
