Planning with TWEAK
by Jonathan Amsterdam
Like all exploratory work in the sciences, AI research proceeds
in cycles of 'scruffy' exploration and 'neat' consolidation.
After years of exploration into different planning algorithm
design strategies, M.I.T.'s David Chapman may have created a new
era in planning research with his neat summary of more than a
decade of scruffy work on an algorithm called TWEAK.
Rete Match Algorithm
by Charles L. Forgy and Susan Shepard
The Rete Match algorithm is a fast method for comparing a set of
patterns to a set of objects to determine all possible matches.
It may be the most efficient algorithm for performing the match
operation on single processor. Developed by Charles L. Forgy in
1974, it has been implemented in several languages in both
research and commercial grade systems.
Imperative Pattern Matching in OPS5
by Dan Neiman
Surely the Rete Match algorithm is an efficient data structure
for implementing production systems. But what else can it be
used for? Let's look at the OPS5 language as a case study of
the Rete net as an experimental tool kit. Then we'll present a
technique that will show the programmer how to use Rete Match as
a general purpose pattern matching tool.
Perceptrons and Neural Nets
by Peter Reece
There are at least ten billion neurons handling over one million
input messages per second in the human brain. With many of the
earlier hardware and software obstacles now overcome, let's look
back to one of the most successful pattern classification
computers---the Perceptron---and show how you can implement a
simple Perceptron on your home computer.
