%description
A compact and explicit machine learning framework for supervised learning,
resampling-based evaluation, hyperparameter tuning, learner comparison,
interpretation, and plug-in g-computation. The package uses standard
formulas for model specification and provides stable S3 interfaces for
fitting, evaluation, tuning, interpretation, and causal estimation across
a learner registry with multiple backend engines. Implemented
interpretation methods build on established approaches such as
permutation-based variable importance, partial dependence, individual
conditional expectation, accumulated local effects, SHAP, and LIME; see

<doi:10.48550/arXiv.1705.07874>, and Ribeiro et al. (2016)
<doi:10.48550/arXiv.1602.04938>. The framework is intentionally
opinionated: preprocessing is expected to occur outside the modeling step,
and the API emphasizes explicit inputs, consistent object contracts, and
compact interfaces rather than feature-by-feature competition with larger
machine learning ecosystems. Plug-in g-computation follows Naimi, Cole,
and Kennedy (2016) <doi:10.1093/ije/dyw323>.
