No support for stratified split in dask_ml.model_selection.train_test_split

20

scikit-learn implementation of train test split (sklearn.model_selection.train_test_split) supports splitting data according to class labels (stratified split) by using the argument `stratify`. This is especially useful when datasets have high class...

Drop in replacement for sklearn.model_selection.permutation_test_score

4

It'd be great to have a dask wrapper for permutation_test_score so that permutations of gridsearches are easier to run in dask.

Avoid compute in datasets

https://github.com/dask/dask-ml/blob/d5801584d092d8f13f1b38aaf4da5dc3caa6a213/dask_ml/datasets.py#L332 isn't great, especially in settings like Hyperband #221, that are using the distributed scheduler. We could probably replace ```python rng = dask_ml.utils.check_random_state(random_state) ``` with ```python rng = sklearn.utils.check_random_state(random_state) ```...

Dask-xgboost example for dask-examples

It would be nice to see an example using the Dask/XGBoost handoff for parallel training and predicting. This is a common question and so would likely have high value. It...
