IconMemberDescription
alpha
Global pruning data

bufIdx
Internal parameters

classIdx
The assigned to the node normalized class index (to 0..class_count-1 range), it is used internally in classification trees and tree ensembles.

complexity
Global pruning data

cvNodeError
Cross-validation pruning data

cvNodeRisk
Cross-validation pruning data

cvTn
Cross-validation pruning data

depth
The node depth, the root node depth is 0, the child nodes depth is the parent's depth + 1.

Equals(Object)
Indicates whether this instance and a specified object are equal.
(Inherited from ValueType.)
Finalize()()()
Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection.
(Inherited from Object.)
GetHashCode()()()
Returns the hash code for this instance.
(Inherited from ValueType.)
GetType()()()
Gets the Type of the current instance.
(Inherited from Object.)
left
Pointer to the left tree node

maxlr
Internal parameters

MemberwiseClone()()()
Creates a shallow copy of the current Object.
(Inherited from Object.)
nodeRisk
Global pruning data

numValid
Internal parameters

offset
Internal parameters

parent
Pointer to the parent tree node

right
Pointer to the right tree node

sampleCount
The number of samples that fall into the node at the training stage. It is used to resolve the difficult cases - when the variable for the primary split is missing, and all the variables for other surrogate splits are missing too, the sample is directed to the left if left->sample_count>right->sample_count and to the right otherwise

split
Pointer to CvDTreeSplit

Tn
The tree index in a ordered sequence of trees. The indices are used during and after the pruning procedure. The root node has the maximum value Tn of the whole tree, child nodes have Tn less than or equal to the parent's Tn, and the nodes with Tn<=CvDTree::pruned_tree_idx are not taken into consideration at the prediction stage (the corresponding branches are considered as cut-off), even if they have not been physically deleted from the tree at the pruning stage.

ToString()()()
Returns the fully qualified type name of this instance.
(Inherited from ValueType.)
treeError
Global pruning data

treeRisk
Global pruning data

value
The value assigned to the tree node. It is either a class label, or the estimated function value.
