Example 5. Jets and Sharks (cont.)
All,
Given a representation of the Jets and Sharks universe in
computer memory, we naturally want to see if that memory
serves to supply the facts a well-constructed data base
should.
In their PDP Handbook presentation of the Jets and Sharks example,
McClelland and Rumelhart suggest several exercises for the reader
to explore the performance of their neural pool memory model on
the tasks of retrieval and generalization (Exercise 2.1).

Using cactus graphs or minimal negations to implement pools of
mutually inhibitory neurons lends itself to neural architectures
on a substantially different foundation from the garden variety
connectionist models. At a high level of abstraction, however,
there is enough homology between the two orders to compare their
performance on many of the same tasks. With that in mind, I tried
Theme One on a number of examples like the ones suggested by
McClelland and Rumelhart.
What follows is a brief discussion of two examples as given in the
original User Guide. Next time I'll fill in more details about the
examples and discuss their bearing on the larger issues at hand.
With a query on the name “ken” we obtain the following output,
giving all the features associated with Ken.
Jets and Sharks • Query 1

With a query on the two features “college” and “sharks” we obtain
the following outline of all features satisfying those constraints.
Jets and Sharks • Query 2

From this we discover all college Sharks are 30‑something and married.
Further, we have a complete listing of their names broken down by occupation.
To be continued …
