WebThe main difference between bagging and random forests is the choice of predictor subset size. If a random forest is built using all the predictors, then it is equal to bagging. Boosting works in a similar way, except that the trees are grown sequentially: each tree is grown using information from previously grown trees. WebLearning tree structure is much harder than traditional optimization problem where you can simply take the gradient. It is intractable to learn all the trees at once. Instead, we use an …
