NAME¶

mlpack::fastmks::FastMKSStat - The statistic used in trees with FastMKS.

SYNOPSIS¶

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 () Modify the self-kernel.

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)).

Detailed Description¶

The statistic used in trees with FastMKS. This stores both the bound and the self-kernels for each node in the tree. Definition at line 35 of file fastmks_stat.hpp.

Constructor & Destructor Documentation¶

mlpack::fastmks::FastMKSStat::FastMKSStat () [inline]¶

Default initialization. Definition at line 41 of file fastmks_stat.hpp.

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

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: Definition at line 56 of file fastmks_stat.hpp. References selfKernel.
