WebClassification ¶ The Ridge regressor has a classifier variant: RidgeClassifier. This classifier first converts binary targets to {-1, 1} and then treats the problem as a regression task, optimizing the same objective as above. The predicted class corresponds to the sign of the regressor’s prediction. WebDec 11, 2024 · Figure 2 visualizes the classification for a threshold of 50%. It seems intuitive to use a threshold of 50% but there is no restriction on adjusting the threshold. So, in the end the only thing that matters is the ordering of the observations. Changing the objective to predict probabilities instead of labels requires a different approach.
