**What it does**
Constructs a pipeline that contains a list of transfroms and a final estimator. Pipeline assembles several steps
that can be cross-validated together while setting different parameters.
please refer to `Scikit-learn pipeline Pipeline`_.

**Pre-processing components** allow None, one or a combination of up to 5 transformations from `sklearn.preprocessing`_, `feature_selection`_, `decomposition`_, `kernel_approximation`_ and/or `cluster.FeatureAgglomeration`_.

**Estimator** selector supports estimators from `xgboost`_ and many scikit-learn modules, including `svm`_, `linear_model`_, `ensemble`_, `naive_bayes`_, `tree`_ and `neighbors`_.
