This examples shows the use of forests of trees to evaluate the importance of features on an artificial classification task. The red bars are the impurity-based feature importances of the forest, along with their inter-trees variability. This example shows the use of forest of trees to evaluat...

When working with datasets that exhibit significant class imbalance, these may not be suitable metrics due to the overwhelming size of the majority class. Waspada et al. [4] use the RF classifier to calculate the importance score of each feature. Features with a low importance score are ...

(Alexander & Du,2020). For imputation, we applied theRpackagemissRanger(Mayer,2021), which uses random forests and implements predictive mean matching due to its benefits for mixed data types, non-linear interactions between variables, and data with a large number of dimensions (Schwerter et al...
The Central Hardwood Forest (CHF) covers a large portion of the eastern United States and is one of the largest forested biomes in the world1. The CHF is currently a major carbon sink (i.e. positive net change of carbon den- sity), similar to many other major temperate forests in the...
Various techniques are used to explain models, one of which is PFI. PFI is a technique used to explain classification and regression models that's inspired by Breiman's Random Forests paper (see section 10). At a high level, the way it works is by randomly shuffling da...
The alteration, fragmentation, and finally loss, of natural habitats are the major causes of the increasingly rapid decline in overall biotic diversity on Earth (Burgess & Sharpe, 1981; Harris, 1984; Saunders et al., 1987). Usually the effects are measur
