sklearn linear classifier

Classifier comparison¶ A comparison of a several classifiers in scikit-learn on synthetic datasets. The point of this example is to illustrate the nature of decision boundaries of different classifiers. This should be taken with a grain of salt, as the intuition conveyed by …

    Jul 30, 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:
