Webb5 jan. 2024 · A random forest classifier is what’s known as an ensemble algorithm. The reason for this is that it leverages multiple instances of another algorithm at the same time to find a result. Remember, decision trees are prone to overfitting. However, you can remove this problem by simply planting more trees!
