The proposed method is based on the use of an ensemble of decision tree classifiers trained using position information and terrain class predictions sampled from weak, slip-based terrain classifiers.doi:10.1007/978-3-030-66151-9_10Ditebogo Masha...

However, the number of features selected in the preprocessing step has not been specified by the authors. The authors evaluated the models using Accuracy, Precision, Recall, and F1 score. When working with datasets that exhibit significant class imbalance, these may not be suitable metrics due to...
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 d...

With over 50 species worldwide, these trees thrive in a variety of habitats, from the snowy peaks of the Himalayas to the temperate forests of North America. Their cones and foliage provide shelter for wildlife, while their wood is used in everything from construction to paper products. But ...
(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 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
