PURPOSE

Provides program support for Chapter 24, Learning by Training
Approximation Nets.  Illustrates interpolation/approximation nets
using vacations.

PERFORMANCE EXPERIMENT 1

Examine the file cast.exp.  Run the interpolation/approximation
learning experiments by typing the following command to your lisp
system:

(load "cast.exp")

Alternatively, evaluate each Lisp expression in the file one at a
time, noting what each does.

PERFORMANCE EXPERIMENT 2

Edit the file cast.lsp, changing the widths of the sigmas used in
the interpolation/approximation experiments.  Run the experiments
again with your altered sigmas.

PERFORMANCE EXPERIMENT 3

Edit the file cast.lsp, modifying the interpolation/approximation
experiments such that the training involves overfitting.  Note
the results.
