메소드	설명
Distance ( double x, double y ) : double	Computes the distance in input space between two points given in feature space.
Estimate ( double inputs, int samples, DoubleRange &range ) : SparseLaplacian	Estimate appropriate values for sigma given a data set. This method uses a simple heuristic to obtain appropriate values for sigma in a radial basis function kernel. The heuristic is shown by Caputo, Sim, Furesjo and Smola, "Appearance-based object recognition using SVMs: which kernel should I use?", 2002.
Function ( double x, double y ) : double	Laplacian Kernel function.
SparseLaplacian ( ) : System	Constructs a new Laplacian Kernel
SparseLaplacian ( double sigma ) : System	Constructs a new Laplacian Kernel
