Random Decision Forests
Here you’ll find everything about decision forests, whether it’s tutorials on implementing decision forests in Python or tuning them with random search.
Decision forests belong to the class of ensemble models. The idea of a Random Forest is to use sets of decision trees instead of individual trees. Finding the right parameters of a decision forest can be challenging or time-consuming using the right optimization technique. Common methods for generating suitable forests are boosting or bagging. Moreover, in practice, a decision forest may have several hundred decision trees. Therefore, decision forests are less transparent in how they make decisions than single decision tree models. Nevertheless, decision forests are widely used because they often achieve excellent performance.
