There's nothing out of the box that will do true online learning. In order for a scikit-learn algorithm to support online learning it must provide the partial_fit function, which RandomForestClassifier does not. I think the code you have given will just refit the entire forest on the subset of data it is currently looking at.

Random Forest Classifier Sklearn Code XpCourse Forest The RandomForestRegressor class of the sklearn.ensemble library is used to solve regression problems via random forest. The most important parameter of the RandomForestRegressor class is the n_estimators parameter. This parameter defines the number of trees in the random forest.

Random Forest Classifier with sklearn. by Chris. Does your model’s prediction accuracy suck but you need to meet the deadline at all costs? Try the quick and dirty “meta-learning” approach called ensemble learning. In this article, you’ll learn about a specific ensemble learning technique called random forests that combines the predictions (or classifications) of multiple machine
