Random forests, or random decision forests, are an ensemble learning method for classification, regression and other tasks that works by constructing a multitude of decision trees during training. For a classification task the forest's output is the class chosen by the largest number of trees; for regression it is the average of the individual trees' predictions, correcting for a single decision tree's tendency to overfit its training set. The first random forest algorithm was developed by Tin Kam Ho in 1995 using the random subspace method, and Leo Breiman and Adele Cutler substantially extended it, with Breiman's 2001 paper becoming the method's standard reference.

Uses Design Technique
Entity-backed identity for the design-technique enum value this algorithm already carries, resolved to a computing concept by an explicit value-to-entity map (phase 3 bucket conversion, docs\design_entity_backed_browse_buckets_20260928.md). The design-technique fact itself stays on the algorithm unchanged.

Random forests or random decision forests is an ensemble learning method for classification, regression and other tasks that works by creating a multitude of decision trees during training. For classification tasks, the output of the random forest is the class selected by most trees. For regression tasks, the output is the average of the predictions of the trees.
Body, history
The first random forest algorithm was developed by Tin Kam Ho in 1995 using the random subspace method. Subsequently, Leo Breiman and Adele Cutler extended the algorithm significantly, with Breiman's 2001 paper becoming highly influential.
