%description
Implements 'Multi-Calibration Boosting' (2018)
<https://proceedings.mlr.press/v80/hebert-johnson18a.html> and
'Multi-Accuracy Boosting' (2019) <doi:10.48550/arXiv.1805.12317> for the
multi-calibration of a machine learning model's prediction. 'MCBoost'
updates predictions for sub-groups in an iterative fashion in order to
mitigate biases like poor calibration or large accuracy differences across
subgroups. Multi-Calibration works best in scenarios where the underlying
data & labels are unbiased, but resulting models are. This is often the
case, e.g. when an algorithm fits a majority population while ignoring or
under-fitting minority populations.
