Enhancing Conformal Prediction via Class Similarity

arXiv:2511.19359v2 Announce Type: replace Abstract: Conformal Prediction (CP) has emerged as a powerful statistical framework for high-stakes classification applications. Instead of predicting a single class, CP generates a prediction set, guaranteed to include the true label with a pre-specified probability. The performance of different CP methods is typically assessed by their average prediction set size. In setups where the classes can be partitioned into semantic groups, e.g., diseases that require similar treatment, users can benefit from prediction sets that are not only small on average

Why this matters
Why now

This paper represents an ongoing academic effort to refine AI predictability and reliability, which becomes increasingly crucial as AI integrates into high-stakes applications.

Why it’s important

Improved Conformal Prediction enhances the trustworthiness and utility of AI systems in critical fields by providing reliable uncertainty quantification.

What changes

AI predictions can now offer more semantically meaningful and potentially smaller prediction sets, increasing their practical applicability, especially where class relationships matter.
