NAME¶

mlpack::kernel::TriangularKernel - The trivially simple triangular kernel, defined by.

SYNOPSIS¶

Public Member Functions¶

TriangularKernel (const double bandwidth=1.0) Initialize the triangular kernel with the given bandwidth (default 1.0). double Bandwidth () const Get the bandwidth of the kernel. double & Bandwidth () Modify the bandwidth of the kernel. template<typename Vec1Type , typename Vec2Type > double Evaluate (const Vec1Type &a, const Vec2Type &b) const Evaluate the triangular kernel for the two given vectors. double Evaluate (const double distance) const Evaluate the triangular kernel given that the distance between the two points is known. std::string ToString () const Return a string representation of the kernel.

Private Attributes¶

double bandwidth The bandwidth of the kernel.

Detailed Description¶

The trivially simple triangular kernel, defined by. where $ b $ is the bandwidth of the kernel. Definition at line 40 of file triangular_kernel.hpp.
