<H1>Decision tree learning code </H1>
<H3>Companion to Chapter 3 of <A

textbook. </H3>This is a simple CommonLisp implementation of the ID3 algorithm
described in Table 3.1 of the textbook. The code also defines the set of
training examples shown in Table 3.2. Therefore, you can modify this code and
experiment with it to create variations on the example trace described in
section 3.4 of the textbook.
<H3>Code</H3>This code is written in CommonLisp. The beginning of the file
contains documentation on how to use it. The file also contains the training
examples.
