Ys. Yeun et al., Smooth fitting with a method for determining the regularization parameter under the genetic programming algorithm, INF SCI, 133(3-4), 2001, pp. 175-194
This paper deals with the smooth fitting problem under the genetic programm
ing (GP) algorithm. To reduce the computational cost required for evaluatin
g the fitness value of GP trees, numerical weights of GP trees are estimate
d by adopting both linear associative memories (LAM) and the Hook and Jeeve
s (HJ) method. The quality of smooth fitting is critically dependent on the
choice of the regularization parameter. So, we present a novel method for
choosing the regularization parameter. Two numerical examples are given wit
h the comparison of generalized cross-validation (GCV) B-splines. (C) 2001
