Which of the following statement is true? A 1. In bagging trees, individual trees are independent of each other. 4. When building a Random Forest model, number of tree should be as large as possible (Ignoring the computational В cost). 2. Random Forests is the method for improving the performance by aggregating the results of weak learners (small trees) and each tree has a high variance with low bias. 3. In order to perform Boosting, we only need to select two parameters: the tree depth d and shrinkage parameter lambda.
