arXiv:2606.24959v1 Announce Type: new Abstract: Ordinal classification (OC) arises in high-stakes domains such as medicine and finance, where uncertainty quantification must account for the severity of ordinal errors. Conformal prediction (CP) provides distribution-free prediction sets with marginal coverage guarantees; however, its practical effectiveness depends critically on the choice of nonconformity function. We introduce a CP method for ordinal classification based on the ranked probability score (RPS), a proper scoring rule defined over cumulative predictive distributions. Although it
The increasing deployment of AI in high-stakes environments, such as medicine and finance, necessitates more robust and reliable methods for uncertainty quantification.
This development improves the trustworthiness and applicability of AI in critical sectors by offering stronger guarantees on prediction reliability, especially for ordinal data where the severity of errors matters.
The ability to provide distribution-free prediction sets with marginal coverage guarantees for ordinal classification using Conformal Prediction based on the ranked probability score enhances the safety and regulatory compliance of AI models.
