Re: [agi] neural network and AGI

[Shane Legg]

Pei,

To my mind the key thing with neural networks is that they
are based on large numbers of relatively simple units that
interact in a local way by sending fairly simple messages.

Of course that's still very broad.  A CA could be considered
a neural network according to this description, and indeed
to my mind I don't see much difference between the two.

Nevertheless, it does rule out many things --- just talk to
somebody who has tried to take a normal algorithm that
does something and turn it into an algorithm that works
on a massively parallel architecture using relatively simple
computations units.

As I see it neural networks are more a paradigm of computation
rather than any specific AI method or technology.  This means
that talking about them in general is difficult.

What you seem to be criticising in your memo is what I'd call
"feed forward neural networks".
