◆ Unique()

template<typename L , typename Y >

static NodePtr gtsam::DecisionTree< L, Y >::Choice< L, Y >::Unique ( const NodePtr & node )

inlinestatic

Merge branches with equal leaf values for every choice node in a decision tree. If all branches are the same (i.e. have the same leaf value), replace the choice node with the equivalent leaf node.

This function applies the branch merging (if enabled) recursively on the decision tree represented by the root node passed in as the argument. It recurses to the leaf nodes and merges branches with equal leaf values in a bottom-up fashion.

Thus, if all branches of a choice node f are the same, just return a single branch at each recursion step.

Parameters

node	The root node of the decision tree.

Returns: NodePtr
