Class DTrees

  • Direct Known Subclasses:
    Boost, RTrees
    public class DTrees
extends StatModel
    The class represents a single decision tree or a collection of decision trees. The current public interface of the class allows user to train only a single decision tree, however the class is capable of storing multiple decision trees and using them for prediction (by summing responses or using a voting schemes), and the derived from DTrees classes (such as RTrees and Boost) use this capability to implement decision tree ensembles.

    • Method Detail

      • __fromPtr__

        public static DTrees __fromPtr__​(long addr)

      • getPriors

        public Mat getPriors()
        SEE: setPriors
        Returns:
        automatically generated

      • create

        public static DTrees create()
        Creates the empty model The static method creates empty decision tree with the specified parameters. It should be then trained using train method (see StatModel::train). Alternatively, you can load the model from file using Algorithm::load<DTrees>(filename).
        Returns:
        automatically generated

      • load

        public static DTrees load​(java.lang.String filepath,
                          java.lang.String nodeName)
        Loads and creates a serialized DTrees from a file Use DTree::save to serialize and store an DTree to disk. Load the DTree from this file again, by calling this function with the path to the file. Optionally specify the node for the file containing the classifier
        Parameters:
        filepath - path to serialized DTree
        nodeName - name of node containing the classifier
        Returns:
        automatically generated

      • load

        public static DTrees load​(java.lang.String filepath)
        Loads and creates a serialized DTrees from a file Use DTree::save to serialize and store an DTree to disk. Load the DTree from this file again, by calling this function with the path to the file. Optionally specify the node for the file containing the classifier
        Parameters:
        filepath - path to serialized DTree
