We will explore mixture models in more depth in part 2 of this series. The important takeaway is that mixture models implement a closely related unsupervised form of density estimation.

Sklearn provides a function train_test_split to do this task. It returns two arrays of data. Here we ask for 20% of the data in the test set. train, test = train_test_split (iris, test_size=0.2, random_state=142) print (train.shape) print (test.shape) scotch whisky society of america
