Public Member Functions

FastMKSStat ()

Default initialization. template<typename TreeType > FastMKSStat (const TreeType &node)

Initialize this statistic for the given tree node. double Bound () const

Get the bound. double & Bound ()

Modify the bound. double LastKernel () const

Get the last kernel evaluation. double & LastKernel ()

Modify the last kernel evaluation. void * LastKernelNode () const

Get the address of the node corresponding to the last distance evaluation. void *& LastKernelNode ()

Modify the address of the node corresponding to the last distance evaluation. double SelfKernel () const

Get the self-kernel. double & SelfKernel ()

Private Attributes

double bound

The bound for pruning. double lastKernel

The last kernel evaluation. void * lastKernelNode

The node corresponding to the last kernel evaluation. double selfKernel

The self-kernel evaluation: sqrt(K(centroid, centroid)).

The statistic used in trees with FastMKS.

This stores both the bound and the self-kernels for each node in the tree.

mlpack::fastmks::FastMKSStat::FastMKSStat ()\fC [inline]\fP

Default initialization.

Definition at line 41 of file fastmks_stat.hpp.

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

Initialize this statistic for the given tree node. The TreeType's metric better be IPMetric with some kernel type (that is, Metric().Kernel() must exist).

Parameters:

node Node that this statistic is built for.
