Reference Issue
Fixes #9339
Part of #9342
What does this implement/fix? Explain your changes.
Basic idea of the example:
(1)plot the data before and after discretization (idea come from this page))
(2)train several classifiers and compare the results through cross validation. The experiment is based on this paper. DecisionTree is used in this paper and we get very similar result. SVC is mentioned in some papers such as this one.
Since current discretization is naive, it seems hard to expect big improvement.
Any other comments?
cc @jnothman. Feel free to close it if there is better example.
