How to Build a Custom Estimator for scikit-learn
Webb2 apr. 2024 · The Pipeline in scikit-learn is built using a list of (key, value) pairs where the key is a string containing the name you want to give to a particular step and value is an estimator object for that step. WebbThis class implements a meta estimator that fits a number of randomized decision trees (a.k.a. extra-trees) on various sub-samples of the dataset and uses averaging to improve the predictive accuracy and control over-fitting.
