WebbRandom forest classifier uses bagging techniques where decision tree classifier is used as base learner. Random forest consists of many trees, and each tree predicts his own classification and the final decision makes by model based on maximum votes of trees (Fig. 7.4). There is very simple and powerful concept behind RF—the wisdom of crowd.
