WebJun 29, 2015 · A large CART model can be grown to fit the data very well, leading to overfitting and a reduced capability to accurately fit new data (robustness). To improve robustness in CART models, one can use cross-validation and cost-complexity pruning, where models are grown on subsets of the data and then some ‘best’ model is selected … WebOverfitting is an undesirable machine learning behavior that occurs when the machine learning model gives accurate predictions for training data but not for new data.

WebFeb 1, 2024 · Accepted Answer. As dpb said, it is impossible to know if some arbitrary value for RMSE is good or bad. Only you know if it is good, because only you can know how much noise you would expect in the data.
