MLJ is a Julia framework for combining and tuning machine learning models. This repository provides core functionality for MLJ, including:

• completing the functionality for methods defined "minimally" in MLJ's light-weight model interface MLJModelInterface (/src/interface)

• definition of machines and their associated methods, such as fit! and predict/transform (src/machines).

• MLJ's model composition interface, including learning networks, pipelines, stacks, target transforms (/src/composition)

• basic utilities for manipulating datasets and for synthesizing datasets (src/data)

• a small interface for resampling strategies and implementations, including CV(), StratifiedCV and Holdout (src/resampling.jl). Actual performance evaluation measures (aka metrics), which previously were provided by MLJBase.jl, now live in StatisticalMeasures.jl.

• methods for performance evaluation, based on those resampling strategies (src/resampling.jl)

• one-dimensional hyperparameter range types, constructors and associated methods, for use with MLJTuning (src/hyperparam)
