dirichletcal 0.5.0

Python code for Dirichlet calibration

Dirichlet Calibration Python implementation

This is a Python implementation of the Dirichlet Calibration presented in Beyond temperature scaling: Obtaining well-calibrated multi-class probabilities with Dirichlet calibration at NeurIPS 2019. The original version used Python 3.8 and reached version 0.4.2. The code started using Python 3.12 from version 0.5.0, you can see the other version in the GitHub history, tags, or in Pypi.
