WebThis visualizer only works for binary classification. A visualization of precision, recall, f1 score, and queue rate with respect to the discrimination threshold of a binary classifier. The discrimination threshold is the probability or score at which the positive class is chosen over the negative class. WebSeveral regression and binary classification algorithms are available in scikit-learn. A simple way to extend these algorithms to the multi-class classification case is to use the so-called one-vs-all scheme.
