[comp.ai.neural-nets] Science centre exhibit on neural nets

tap@ai.toronto.edu (Tony Plate) (07/22/89)

Does anyone have any good ideas for a science center exhibit
on neural networks which will give the average visitor some
idea of what neural networks are about?

I'm helping to design a neural networks exhibit for the
Ontario Science Center, a science "museum" in Toronto.

The exhibit will probably be interactive - with a few
buttons or knobs the visitor can play with.  The exhibit
should be something which a person with high school
education understand.  The concepts involved in it should be
simple, concrete and interesting - thus things like truth
tables are out because they are both abstract and incredibly
boring.

One problem is that many simple neural networks don't do
very surprising or difficult things, e.g. Xor is not really
a very difficult problem, it is only interesting to
researchers because we know that a perceptron cannot do it.

The network has to be simple because the computers available
are not very powerful, and we would like it to learn while
the visitor is with the exhibit, i.e. in 2 to 5 minutes.
They are using Amigas, which seem to be able to do about
1200 link per second for back-propagation training (but
maybe that could be improved by doing integer arithmetic and
table lookup).

We already have a few ideas, but none of them are truly
inspirational, so I shan't bore you with them.

So if you have or have heard of any good ideas for an
interesting and understandable exhibit networks, please mail
them to me.  If there is enough interest I will post
a summary to comp.ai.neural-nets.

More context:
 The exhibit is to be part of a rather large show on
Psychology, which will stay on show in Toronto for
approximately 8 months, and then move to a museum in the
U.S.  The organizers want a section on AI, but have decided
that this section will consist of one exhibit on neural
networks...

I'm not getting paid for this, so neither will you if you
contribute a great idea.  However, I will do my best to make
sure you get credited.  My connection with the ontario
science center is entirely informal, so if you don't want to
give away all rights to your ideas, then don't mail them to me.

Tony,

One simple demonstration is to show how a nn can recognise
patterns. For example, one can present a serie of characters to
the nn to be learnt. After the learning phase, one can recover
a correct character presenting a corrupted version. With a good
graphical interface, I think this example can be interesting.

If the graphical interface is a little bit better, a true image
could be presented to the nn (like a picture of a car, house,
horse, tree etc).
