    Jul 13, 2020 · The first classifier that comes up to my mind is a discriminative classification model called classification trees (read more here). The reason is that we get to see the classification rules and it is easy to interpret. Let’s build one using sklearn (documentation), with a maximum depth of 3, and we can check its accuracy on the test data:
