This functions cleans up any dynamic memory assigned by the node. It will recursively clear the memory for the left and right child nodes.

This function returns a deep copy of the ClusterTreeNode and all it's children. The user is responsible for managing the dynamic data that is returned from this function as a pointer.

This function returns the cluster label.

This function returns the featureIndex, this is index in the input data that the decision threshold is computed on.
Definition at line 208 of file ClusterTreeNode.h.

This function returns the nodeSize, this is the number of training samples that reached the node during the training phase.
Definition at line 199 of file ClusterTreeNode.h.

This function returns the threshold, this is the value used to compute the decision threshold.

This loads the ClusterTreeNode parameters from a file.

This function predicts if the input is greater than or equal to the nodes threshold. If the input is greater than or equal to the nodes threshold then this function will return true, otherwise it will return false.
NOTE: The threshold and featureIndex should be set first BEFORE this function is called. The threshold and featureIndex can be set by training the node through the DecisionTree class.

inlinevirtual |
This function recursively predicts if the probability of the input Vector. If this node is a leaf node, then the class likelihoods are equal to the class probabilities at the leaf node. If this node is not a leaf node, then this function will recursively call the predict function on either the left or right children until a leaf node is reached.
NOTE: The threshold, featureIndex and classProbabilities should be set first BEFORE this function is called. The threshold, featureIndex and classProbabilities can be set by training the node through the DecisionTree class.

This saves the ClusterTreeNode custom parameters to a file. It will be called automatically by the Node base class if the saveToFile function is called.

This function sets the Cluster Tree Node.
nodeSize | sets the node size, this is the number of training samples at that node |

threshold | set the threshold value used for the spilt |
clusterLabel | the cluster label for this node |
