    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 …

    Jul 21, 2020 · Random forest is an ensemble of decision tree. Random forest helps avoid overfitting which is one of the key problem with decision tree classifier. For creating random forest, multiple trees are created using different sample sizes and features set. One of the key hyper parameter of random forest is number of trees represented using n_estimators
