Fix overfitting
WebAug 15, 2014 · 10. 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: Webr/learnmachinelearning. Join. • 22 days ago.

Reduce the capacity of the network (e.g. decrease number of layers or number of hidden units) Reduce the batch size. Share. WebMar 20, 2014 · So use sklearn.model_selection.GridSearchCV to test a range of parameters (parameter grid) and find the optimal parameters. You can use 'gini' or 'entropy' for the Criterion, however, I recommend sticking with 'gini', the default. In the majority of cases, they produce the same result but 'entropy' is more computational expensive to compute.
WebSep 26, 2024 · Overfitting is a very basic problem that seems counterintuitive on the surface. Simply put, overfitting arises when your model has fit the data too well . That can seem weird at first glance.
