%description
An algorithm for fitting interpretable additive neural networks for
identifiable and visualizable feature effects using post hoc
orthogonalization. Fit custom neural networks intuitively using
established 'R' 'formula' notation, including interaction effects of
arbitrary order while preserving identifiability to enable a functional
decomposition of the prediction function. For more details see Koehler et
al. (2025) <doi:10.1038/s44387-025-00033-7>.
