Ordinal Classification Python Packages

coral-pytorch

CORAL and CORN implementations for ordinal regression with deep neural networks.

dlordinal

Open-source Python toolkit focused on deep learning with ordinal methodologies

coral-ordinal

Tensorflow Keras implementation of ordinal regression using consistent rank logits (CORAL) by Cao et al. (2019)

choircert

A distribution-free conformal prediction certification layer for safety-critical ordinal classification. Guarantees contiguous prediction sets, marginal/group-conditional validity, true-label coverage under banded reporting noise, and severity-weighted risk control (fatal-omission bounds) with an explicit additive slack budget.

ordinalgbt

A package to build Gradient boosted trees for ordinal labels

optimized-rounder

Optimized Rounder: An efficient optimizer for finding optimal thresholds in ordinal classification problems. This package uses Optuna for efficient threshold search with support for cross-validation and multiple evaluation metrics.
