Detailed Description

template<typename MetricType, typename StatisticType = EmptyStatistic, typename MatType = arma::mat, template< typename HyperplaneMetricType > class HyperplaneType = AxisOrthogonalHyperplane, template< typename SplitMetricType, typename SplitMatType > class SplitType = MidpointSpaceSplit>

class mlpack::tree::SpillTree< MetricType, StatisticType, MatType, HyperplaneType, SplitType >::SpillDualTreeTraverser< MetricType, StatisticType, MatType, HyperplaneType, SplitType >

A generic dual-tree traverser for hybrid spill trees; see spill_dual_tree_traverser.hpp for implementation.

The Defeatist template parameter determines if the traverser must do defeatist search on overlapping nodes.

Member Function Documentation

Traverse()

template<typename MetricType , typename StatisticType , typename MatType , template< typename HyperplaneMetricType > class HyperplaneType, template< typename SplitMetricType, typename SplitMatType > class SplitType>

template<typename RuleType , bool Defeatist>

void mlpack::tree::SpillTree< MetricType, StatisticType, MatType, HyperplaneType, SplitType >::SpillDualTreeTraverser< RuleType, Defeatist >::Traverse	(	SpillTree &	queryNode,
		SpillTree &	referenceNode,
		const bool	bruteForce = false
	)

Traverse the two trees.

This does not reset the number of prunes.

Parameters

queryNode	The query node to be traversed.
referenceNode	The reference node to be traversed.
bruteForce	If true, then do a brute-force search on the reference node instead of traversing any further.
