WebAug 26, 2024 · However, although the random forest overfits, it is able to generalize much better to the testing data than the single decision tree. If we inspect the models, we see that the single decision tree reached a maximum depth of 55 with a total of 12327 nodes. The average decision tree in the random forest had a depth of 46 and 13396 nodes.
