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:
WebOct 15, 2024 · Underfitting and Overfitting. A Classification Example. Suppose that there are two categories in dataset – cats and dogs. A good model that explains all the data, looks like a quadratic function with a few errors: Following the same logic from our previous example, what would be considered an underfitted model?
