Authors@R: person("Gustavo", "Pereira", role = c("aut", "cre"), email = "tanopereira@gmail.com")
Description: Automates feature engineering using evolutionary algorithms
    inspired by genetic programming. Starting from raw input features, the
    package evolves candidate transformation recipes through selection,
    crossover, and mutation, evaluating fitness via cross-validation or
    train/validation splits with gradient-boosted tree models ('LightGBM' or
    'XGBoost'). Built-in transformers include arithmetic, logarithmic, and
    power operations, interaction terms, target encoding, quantile and
    log-based binning, principal component analysis, truncated singular value
    decomposition, Uniform Manifold Approximation and Projection (UMAP)
    dimensionality reduction, and minimum spanning tree (MST) graph-based
    clustering. The evolutionary search yields an optimised feature recipe
    that can be applied to new data for prediction. Methods are described in
