Every algorithm consists of two steps: Producing a distribution of simple ML models on subsets of the original data. Combining the distribution ...Sat, 04 Apr 2026 22:11:00 GMThttps://stats.stackexchange.com/questions/447630/why-do-we-use-random-sample-with-replacement-while-implementing-random-forestLet's say we want to build random forest. Wikipedia says that we use random sample with replacement to do bagging. I don't understand why we can't use random sample without replacement.Sat, 04 Apr 2026 18:22:00 GMThttps://stats.stackexchange.com/questions/602552/subset-differences-between-bagging-random-forest-boostingBagging draws a bootstrap sample of the data (randomly select a new sample with replacement from the existing data), and the results of these random samples are aggregated (because the trees' predictions are averaged). But bagging, and column subsampling can be applied more broadly than just random forest.Wed, 01 Apr 2026 03:45:00 GMThttps://stats.stackexchange.com/questions/264129/what-is-the-difference-between-bagging-and-random-forest-if-only-one-explanatory29 " The fundamental difference between bagging and random forest is that in Random forests, only a subset of features are selected at random out of the total and the best split feature from the subset is used to split each node in a tree, unlike in bagging where all features are considered for splitting a node."Sat, 04 Apr 2026 12:03:00 GMThttps://stats.stackexchange.com/questions/365437/what-are-advantages-of-random-forests-vs-using-bagging-with-other-classifiersRandom forests are actually usually superior to bagged trees, as, not only is bagging occurring, but random selection of a subset of features at every node is occurring, and, in practice, this reduces the correlation between trees, which improves the effectiveness of the final averaging step.Thu, 12 Mar 2026 13:13:00 GMThttps://stats.stackexchange.com/questions/372634/boosting-and-bagging-trees-xgboost-lightgbmBoth XGBoost and LightGBM have params that allow for bagging. The application is not Bagging OR Boosting (which is what every blog post talks about), but Bagging AND Boosting. What is the pseudo code for where and when the combined bagging and boosting takes place? I expected it to be "Bagged Boosted Trees", but it seems it is "Boosted Bagged ...Wed, 25 Mar 2026 04:22:00 GMThttps://stats.stackexchange.com/questions/318770/difference-between-random-forest-vs-bagging-in-sklearnSo Bagging algorithm using a decision tree would use all the features to decide the best split. On the other hand, the trees built in Random forest use a random subset of the features at every node, to decide the best split.Sat, 04 Apr 2026 18:22:00 GMThttps://stats.stackexchange.com/questions/77018/is-random-forest-a-boosting-algorithmA random forest, in contrast, is an ensemble bagging or averaging method that aims to reduce the variance of individual trees by randomly selecting (and thus de-correlating) many trees from the dataset, and averaging them.Thu, 02 Apr 2026 05:24:00 GMThttps://stats.stackexchange.com/questions/380023/how-can-we-explain-the-fact-that-bagging-reduces-the-variance-while-retaining-tI am able to understand the intution behind saying that "Bagging reduces the variance while retaining the bias". What is the mathematically principle behind this intution?
