Learning neural nets learn by a process of trial and error. A new
link is added, or an existing link is weighted differently, or some
similar change is made. Then the net gets feedback and judges it's new
connection accordingly. The whole process takes place with no creativity
involved. A simple exanple is on the shelf at your local software store
in the section labeled 'optical character recognition'.
Thus, having an element of the set 'neural nets' without the characteristic
'creativity', I feel confident in stating that neural nets don't demand
creativity.
But then what is one to think about the fact that creativity does arise
in some neural nets, especially the more complicted ones? So I called
it an artifact.
And QM requested:
> ...define artifact
Off the top of my head: an artifact is something that appears from a
system, but is not essential to its functioning.
I was surprised that some people took this term to be pejorative. It was
simply intended to be discriptive. I readers prefer, I could substitute
the phrase 'emergent behavior' without significantly changing the meaning.
Natasha's pre-quibble post continued:

And my pre-quibble response continued:

Whereupon QM admonished:

Oops! I got caught making assertions that I can't support. How embarrasing!
I guess I just tapped into our cultural mythology about artists because it
seemed convenient to confirm my ideas. But I know of no study that
demonstrates the converse either. I still suspect that it may be true.
Anybody got any hard data on this, pro or con? [ Please hurry so KA can
cancel her reservations :) ]
I stumbled to the conclusion mainly through my experience - both professional
and recreational - with neural nets on computers. I have seen that allowing
a net to alter its pathways a little is part of its learning process, and
that sometimes this results in useful but unexpected constructions that can
best be labeled 'creative'. And I have further seen that too much altering
can result in behavior that can only be described as 'insane'.
The whole point of this post was to try to get a grip on the mechanism
of creativity, not to offend artists. I'll do some more thinking
and post more on it later.
