Classifier versus regressor

Oct 25, 2020 Regression and classification algorithms are different in the following ways: Regression algorithms seek to predict a continuous quantity and classification algorithms seek to predict a class label. The way we measure the accuracy of regression and classification models differs

    Should I choose Random Forest regressor or classifier?

    Jan 04, 2017 Whether you use a classifier or a regressor only depends on the kind of problem you are solving. You have a binary classification problem, so use the classifier. I could run randomforestregressor first and get back a set of estimated probabilities. NO. You don't get probabilities from regression

    The task of the classification algorithm is to map the input value (x) with the discrete output variable (y). Regression Algorithms are used with continuous data. Classification Algorithms are used with discrete data. In Regression, we try to find the best fit line, which can predict the output more accurately

By contrast, setting k at ten, so that ten total points are averaged together for prediction yields a much smoother ride: KNN regressor with K set to 10
