Class GaussCh1<T extends MLVector<?>>

java.lang.Object
  fr.lip6.kernel.Kernel<T>
      fr.lip6.kernel.GaussCh1<T>

Type Parameters:

T -

public class GaussCh1<T extends MLVector<?>>
extends Kernel<T>

Gaussian kernel using "Chi 1" distance :
k(x,y) = exp(d(x,y)), with d Chi1 distance. The Chi1 distance is similar to a Chi square distance, but with Math.abs() instead of Math.pow().
