Web5 de mai. de 2015 · Because each tree is i.i.d., you can just train a large number of trees and pick the smallest n such that the OOB error rate is basically flat. By default, randomForest will build trees with a minimum node size of 1. This can be computationally expensive for many observations.
random forest - RandomForestClassifier OOB scoring method
WebContrary to the OOB-based method, the second approach avoids the loss of information by using 90% of the training data for model building and the remaining 10% for model assessment. Furthermore, the proposed methods also ensure having accurate and diverse models in the final ensemble, where accuracy and diversity significantly regulate the … Web15 de dez. de 2024 · 我很难找到 oob_score_ 在scikit-learn中对Random Forest Regressor的意义 . 在文档上说:. oob_score_ : float使用袋外估计获得的训练数据集的分数 . 起初我 … solo mine on nicehash
