SpletThe goal of ensemble algorithms is to combine the predictions of several base estimators built with a given learning algorithm in order to improve robustness over ... n_estimators. The n_estimators is the number of trees to be used in the Random Forest. Since Random Forest algorithm is an ensemble method comprising of creating multiple ... SpletEstimators usually have two main methods: fit (): This method is used to train the estimator on the input data (also known as fitting or learning). It takes the feature matrix (X) and, for supervised learning, the target values (y). predict (): This method is used to make predictions using the trained estimator. la torta downtown fresno
