%description
Provides wrapper of various machine learning models. In applied machine
learning, there is a strong belief that we need to strike a balance
between interpretability and accuracy. However, in field of the
interpretable machine learning, there are more and more new ideas for
explaining black-box models, that are implemented in 'R'. 'DALEXtra'
creates 'DALEX' Biecek (2018) <arXiv:1806.08915> explainer for many type
of models including those created using 'python' 'scikit-learn' and
'keras' libraries, and 'java' 'h2o' library. Important part of the package
is Champion-Challenger analysis and innovative approach to model
performance across subsets of test data presented in Funnel Plot.
