These instruction cover installation of the code for the
naive bayes tutorial.  They expect you have installed the
decision tree code according to the instructions given last
week.

Create a directory for the naive bayes software:

> cd intro-to-ai
> mkdir naive-bayes
> cd naive-bayes

Copy naive-bayes.tar.gz from the course directory.
Extract naive-bayes.tar.gz in the directory you just
created for it.

> cp /bham/common/courses/ai-intro/source/naive-bayes.tar.gz .
> tar -zxvf naive-bayes.tar.gz

This will create one directory: 

  src/ contains the code you will use

Change to the src directory.

> cd src

Run SISC:

> sisc

From within SISC load spam-filter.scm

> (load "spam-filter.scm")

Remember:

  - if you want to inspect the corpus directly, it lives in

    /bham/common/courses/ai-intro/corpus/


  - SISC documentation is available locally:

    file:///bham/common/courses/ai-intro/sisc/doc/index.html


  - For debugging there is a useful command
