Generalization error rate of a tree

WebA decision tree algorithm is used to separate the features of a data set via a cost function. The optimization of a decision tree in purpose to eliminate branches that use irrelevant features is known as pruning. By adjusting the depth parameter of the decision tree, the risk of overloading or the complexity of the algorithm can be reduced. WebApr 13, 2024 · The accurate identification of forest tree species is important for forest resource management and investigation. Using single remote sensing data for tree species identification cannot quantify both vertical and horizontal structural characteristics of tree species, so the classification accuracy is limited. Therefore, this study explores the …
