    Aug 01, 2017 · Random forest algorithm is an ensemble classification algorithm. Ensemble classifier means a group of classifiers. Instead of using only one classifier to predict the target, In ensemble, we use multiple classifiers to predict the target. In case, of random forest, these ensemble classifiers are the randomly created decision trees

    Introduction. Random forest is a supervised learning algorithm which is used for both classification as well as regression. But however, it is mainly used for classification problems. As we know that a forest is made up of trees and more trees means more robust forest. Similarly, random forest algorithm creates decision trees on data samples and then gets the prediction from each of them and finally selects the …

    The random forest algorithm combines multiple algorithm of the same type i.e. multiple decision trees, resulting in a forest of trees, hence the name "Random Forest". The random forest algorithm can be used for both regression and classification tasks. How the Random Forest Algorithm Works. The following are the basic steps involved in performing the random forest algorithm: Pick N random records from the …
