fklearn: Functional Machine Learning

fklearn uses functional programming principles to make it easier to solve real problems with Machine Learning.

The name is a reference to the widely known scikit-learn library.

fklearn Principles

1. Validation should reflect real-life situations.
2. Production models should match validated models.
3. Models should be production-ready with few extra steps.
