Chapter 9 Decision Trees. Tree-based models are a class of nonparametric algorithms that work by partitioning the feature space into a number of smaller non-overlapping regions with similar response values using a set of splitting rules.Predictions are obtained by fitting a simpler model e.g., a constant like the average response value in each region.

Jul 25, 2021 1. My question is how the prediction in the leaf is calculated for classification trees with more than 2 classes. With regression trees its simple, its just the sample mean of the observations ending up in that leaf of the training sample. With binary classification its the same and then you decide 1 if the result is 0.5 and 0 if it is 0.5.
