function v = kernel(x, y)
%KERNEL Calculates the kernel function of a pair of vectors

% Good ones
%v = (x*y'+1)^1;
%v = ((x*y'+1)^2)/8000;

% Ok ones?
%v = exp(-1*(norm(x-y)^2)/100);
%v = ((x*y'+1)^4)/6400000000;
%v = exp(-1*(norm(x-y)^2)/10)*25;

%v = exp(-1*(norm(x-y)^2)/100000)*25;
v = exp(-1*(norm(x-y)^2)/100)*25;
%v = exp(-1*(norm(x-y)^2)/2);
