During May 2025, Toby Hocking refactored the Resampling class in the mlr-org/mlr3 repository, introducing a private get_instance method to centralize the creation of training and test sets. This object-oriented approach in R streamlined the customization of stratification and grouping, reducing code duplication and improving maintainability across resampling workflows. By consolidating this logic, Toby enhanced the reproducibility and consistency of benchmarking experiments, making it easier for contributors to onboard and extend evaluation strategies. The work demonstrated a strong grasp of software design patterns and R package development, laying a robust foundation for future enhancements in experimental workflows.
