The class represents a decision tree node.
cv::ml::DTrees::Node::Node | ( | ) |
int cv::ml::DTrees::Node::classIdx |
Class index normalized to 0..class_count-1 range and assigned to the node. It is used internally in classification trees and tree ensembles.
int cv::ml::DTrees::Node::defaultDir |
Default direction where to go (-1: left or +1: right). It helps in the case of missing values.
int cv::ml::DTrees::Node::left |
Index of the left child node.
int cv::ml::DTrees::Node::parent |
Index of the parent node.
int cv::ml::DTrees::Node::right |
Index of right child node.
int cv::ml::DTrees::Node::split |
Index of the first split.
double cv::ml::DTrees::Node::value |
Value at the node: a class label in case of classification or estimated function value in case of regression.
