Gradient lifting decision tree
WebEach decision tree is given a subset of the dataset to work with. During the training phase, each decision tree generates a prediction result. The Random Forest classifier predicts the final decision based on most outcomes when a new data point appears. Consider the following illustration: How Random Forest Classifier is different from decision ... WebAug 15, 2024 · Decision trees are used as the weak learner in gradient boosting.
