Projection pursuit regression (SMART)
Multivariate adaptive regression splines
k-nearest neighbors and Constrained topological mapping
Constrained topological mapping

example on implementation of custom kernel function.
Version 2.05, 19-oct-2005: A new library for optimization of
Generalized Non-negative Least Squares problem (gnnls.m) and Generalized
Nearest Point problem (gnpp.m) added.

method (by Burges, 1996) for homogeneous second order polynomial
Version 2.03, 14-dec-2004: Added new solvers for the binary SVM problem with
L2-soft margin (svm2.m) and multi-class BSVM formulation with L2-soft margin
