Edward, Your reply raised very interesting issues which I'll have to think about some more. I'll also need to read Valiant's paper to get a better idea of realistic properties of the brain regarding this kind of process. So, I'll answer in more detailed way when I'm ready.
For now, I have to admit that I somewhat shoot myself in the foot with that estimation: I didn't intend to imply that cell assemblies are rigid (which I did do in last sentences). You summarized that paragraph correctly, btw. I skipped a very important issue of structure-formation, and I'm not sure how to proceed about it in brain setting. Let's consider the following 'use case': there are two concepts, A and B, which are originally unrelated. When they are repeatedly observed together, they should start referencing each other, so that activation of A alone tends to activate B. This is a more strong requirement: in my estimation I searched for _any_ neuron which will be able to notice regularity, but here some neuron that is _included in B_ must notice that A is active, even though A and B are originally not related to each other. -- Vladimir Nesov mailto:[EMAIL PROTECTED] ----- This list is sponsored by AGIRI: http://www.agiri.org/email To unsubscribe or change your options, please go to: http://v2.listbox.com/member/?member_id=8660244&id_secret=56074478-a3abcb
