WebIf overtraining or model complexity results in overfitting, then a logical prevention response would be either to pause training process earlier, also known as, “early stopping” or to reduce complexity in the model by eliminating less relevant inputs. WebAug 14, 2014 · For decision trees there are two ways of handling overfitting: (a) don't grow the trees to their entirety (b) prune The same applies to a forest of trees - don't grow them too much and prune. I don't use randomForest much, but to my knowledge, there are several parameters that you can use to tune your forests:

"WebOverfitting. The process of recursive partitioning naturally ends after the tree successfully splits the data such that there is 100% purity in each leaf (terminal node) or when all splits have been tried so that no more splitting will help. Reaching this point, however, overfits the data by including the noise from the training data set. " - How to solve overfitting problem
