Basically, a random forest is an average of tree estimators. Definition A random forest is a classifier consisting of a collection of tree-structured classifiers {h(x,Θk), k=1, } where the {Θk} ous extensions to random forests including online learning, survival analysis and clustering problems. It is very simple and e ective but there is still a large gap between theory and practice. It is very simple and e ective but there is still a large gap between theory and practice.
