The extra trees algorithm, like the random forests algorithm, creates many decision trees, but the sampling for each tree is random, without replacement. This creates a dataset for each tree with unique samples. A specific number of features, from the total set of features, are also ...

We meticulously analyzed several prominent ML algorithms, namely the random forest regression [23], decision tree regression [24], extra-trees regression (ETR) [21], AdaBoost regression [25], etc. Through the rigorous application of the 10-fold cross-validation technique, we aim to identify the...
The Extra-Trees algorithm builds an ensemble of unpruned decision or regression trees according to the classical top-down procedure. Its two main differences with other tree-based ensemble methods are that it splits nodes by choosing cut-points fully at random and that it uses the whole learning...
