imbalanced-calibrate - Analytical Calibration for Imbalanced Learning
This package provides sklearn-compatible calibration methods which correct model output for the bias induced by certain imbalanced learning techniques. It supports class weighting in sklearn binary classifiers (including XGBoost and LightGBM), and resampling methods from the imbalanced-learn package.
Documentation
Installation instructions, usage examples and mathematical justification can be found in the documentation.
Prerequisites
imbalanced-calibrate requires the following dependencies:
- Python (>=3.10)
- NumPy (>=2.0.2)
- Scikit-learn (>=1.6.0)
Additionally, imbalanced-calibrate requires the following optional dependencies:
- Imbalanced-learn (>=0.14.2), for calibration after using
imbalanced-learnresampling methods.
Install
imbalanced-calibrate is currently available on the PyPI repository and you can install it via pip:
pip install imbalanced-calibrate
Or with uv:
uv add imbalanced-calibrate
The optional dependencies for resampling methods can be installed using pip install imbalanced-calibrate[resampling] or uv add "imbalanced-calibrate[resampling]".
