mlpack_emst_DTBStat: A statistic for use with mlpack trees, which stores the upper bound on distance to nearest neighbors and the component which this node belongs to.

SYNOPSIS

Private Attributes

double bound

Total bound for pruning. int componentMembership

The index of the component that all points in this node belong to. double maxNeighborDistance

Upper bound on the distance to the nearest neighbor of any point in this node. double minNeighborDistance

Lower bound on the distance to the nearest neighbor of any point in this node.

Detailed Description

A statistic for use with MLPACK trees, which stores the upper bound on distance to nearest neighbors and the component which this node belongs to.

Constructor & Destructor Documentation

mlpack::emst::DTBStat::DTBStat ()\fC [inline]\fP

A generic initializer. Sets the maximum neighbor distance to its default, and the component membership to -1 (no component).

Definition at line 59 of file dtb_stat.hpp.

template<typename TreeType > mlpack::emst::DTBStat::DTBStat (const TreeType &node)\fC [inline]\fP

This is called when a node is finished initializing. We set the maximum neighbor distance to its default, and if possible, we set the component membership of the node (if it has only one point and no children).

Parameters:

node Node that has been finished.
