**What it does**

Given an estimator and dataset, this tool fits the estimator with part of the datasets and evalue the performance of the fitted estimator on the rest of the datasets. It consists of two modes: train-test and train-val-test.

- train-test: data sets will be split into train and test portions. Estimator is training on the train portion, and performance is evaluated on the test portion.

- train-val-test: data sets are split into three portions, train, val and test. Validations happen along with the training process, which is often useful in **deep learnings**.

**Output**

Performance scores.
