%description
Provides Python-based extensions to enhance data analytics workflows,
particularly for tasks involving data preprocessing and predictive
modeling. Includes tools for data sampling, transformation, feature
selection, balancing strategies (e.g., SMOTE), and model construction.
These capabilities leverage Python libraries via the reticulate interface,
enabling seamless integration with a broader machine learning ecosystem.
Supports instance selection and hybrid workflows that combine R and Python
functionalities for flexible and reproducible analytical pipelines. The
architecture is inspired by the Experiment Lines approach, which promotes
modularity, extensibility, and interoperability across tools. More
information on Experiment Lines is available in Ogasawara et al. (2009)
<doi:10.1007/978-3-642-02279-1_20>.
