Distributed Random Forest (DRF) is a powerful classification and regression tool. When given a set of data, DRF generates a forest of classification or regression trees, rather than a single classification or regression tree. Each of these trees is a weak learner built on a subset of rows and columns. More trees will reduce the variance.

Random Forest is a ensemble bagging algorithm to achieve low prediction error. It reduces the variance of the individual decision trees by randomly selecting trees and then either average them or picking the class that gets the most vote. Bagging is a method for generating multiple versions of a predictor to get an aggregated predictor

Random Forest; Random Forest (Concurrency) Synopsis This Operator generates a random forest model, which can be used for classification and regression. Description. A random forest is an ensemble of a certain number of random trees, specified by the number of trees parameter. Jan 17, 2020 · 6 min read.

One of the most common Machine Learning algorithms in the world of data science is Decision Trees because it’s easy to implement and understand even if you have limited knowledge of how Machine Learning works. An extension to the Decision Tree algorithm is Random Forests, which is simply growing multiple trees at once, and choosing the most common or average value as the final result. First, Random Forest algorithm is a supervised classification algorithm. We can see it from its name, which is to create a forest by some way and make it random.
