One of the ways to prevent Overfitting is to training with the help of more data. Such things make easy for algorithms to detect the signal better to minimize errors. 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.
