sklearn random forest classifier

May 09, 2020 · A random forest classifier is, as the name implies, a collection of decision trees classifiers that each do their best to offer the best output. Because we talk about classification and classes and there's no order relation between 2 or more classes, the final output of the random forest classifier is the mode of the classes

    Classification is a big part of machine learning. Random Forest Classifier is a flexible, easy to use algorithm used for classifying and deriving predictions based on the number of decision trees. So, Random Forest is a set of a large number of individual decision trees operating as an ensemble. Each individual tree spits out as a class prediction

    Jan 10, 2018 · (The parameters of a random forest are the variables and thresholds used to split each node learned during training). Scikit-Learn implements a set of sensible default hyperparameters for all models, but these are not guaranteed to be optimal for a problem. The best hyperparameters are usually impossible to determine ahead of time, and tuning a
