Class GaussChi1<T extends MLVector<?>>

java.lang.Object
  extended by fr.lip6.kernel.Kernel<T>
      extended by fr.lip6.kernel.GaussChi1<T>
Type Parameters:
T -
All Implemented Interfaces:
java.io.Serializable

public class GaussChi1<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().
