fklearn is a Python machine learning library from Nubank that applies functional programming principles to build, validate, and deploy models. It wraps model backends like LightGBM, XGBoost, and CatBoost with composable, reproducible pipelines whose validation reflects real-life scenarios.

Use cases

  • train and validate machine learning models with realistic validation splits
  • build reproducible ML pipelines that match production behavior
  • compare LightGBM, XGBoost, and CatBoost models in one framework
  • analyze model results in depth with built-in evaluation tools
  • deploy validated models to production with minimal extra steps

When to avoid

  • you need deep learning or PyTorch-based workflows
  • you prefer the vast scikit-learn ecosystem and its integrations
  • you work outside Python or outside pandas-based data pipelines
