%description
Measure fairness metrics in one place for many models. Check how big is
model's bias towards different races, sex, nationalities etc. Use measures
such as Statistical Parity, Equal odds to detect the discrimination
against unprivileged groups. Visualize the bias using heatmap, radar plot,
biplot, bar chart (and more!). There are various pre-processing and
post-processing bias mitigation algorithms implemented. Package also
supports calculating fairness metrics for regression models. Find more
details in (Wiśniewski, Biecek (2021)) <arXiv:2104.00507>.
