sklearn classifier

A multi-label model that arranges binary classifiers into a chain. Each model makes a prediction in the order specified by the chain using all of the available features provided to the model plus the predictions of models that are earlier in the chain.

    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:

    Introduction Classification is a large domain in the field of statistics and machine learning. Generally, classification can be broken down into two areas: 1. Binary classification, where we wish to group an outcome into one of two groups. 2. Multi-class classification, where we wish to group an outcome into one of multiple (more than two) groups. In this post, the main focus will be on using
