we can now consider some of the reasons why tree-based methods are so popular among practitioners. First — and very importantly — individual trees are often useful for gaining insight into the geometry of datasets in high dimensions. This is ...

I am using sklearn's DecisionTreeClassifier in a multi-label situation. I have a matrix where each column represents whether an item is in the list, which I'm also trying to predict. See example below. import numpy as np from sklearn.tree import DecisionTreeClassifier x = np.array([[...
-force=false: Force at least one non constant feature to be tested for each split as in scikit-learn. -impute=false: Impute missing values to feature mean/mode before growth. -nCores=1: The number of cores to use. -progress=false: Report tree number and running oob error. -oobpreds=...

A single tree is probably not useful to interpret as part of an ensemble. The node is the output/prediction or split point for prediction – I don’t recall sorry – perhaps check the documentation. The model automatically performs feature selection/importance weighting as part of training. All...
