+            feature space.  It can be used to kernelize any algorithm that requires only
             the ability to perform vector addition, subtraction, scalar multiplication,
             and inner products.  It uses the sparsification technique described in the 
             paper The Kernel Recursive Least Squares Algorithm by Yaakov Engel.
