Hi, I am new to the list and I guess fairly new to AI in general...though I have done a lot of reading about AI abstracts from universities like MIT, CalTech,...

Hi Jim, ... Welll, most neural network books and courses are about traditional neural networks. The problem with them is that they don't care about the exact...

Juha, This was an excellent post - thanks. I do have a question though - if the brain lacks a backpropogation like mechanism then is it really a combination of...
... There are different learning 'algorithms' in the brain too, but it they're not exactly like backpropagation. Usually backpropagation algorithms adjust the...
... Actually, some researchers believe there is a process like backpropagation in the brain. Correlated pre- and post-synaptic firing causes not only change in...
... Yes, it's possible that something a postsynaptic neuron does will cause a chain of events which will change the way the presynaptic neuron works, and this...
I found a book by Gerstner on spiking neurons in HTML form: http://diwww.epfl.ch/~gerstner/BUCH.html This may quite complicated at some points, but it may...

... I think the spikes itself are not inhibitory and I've never heard of spikes propagating as hyperpolarization. The resting potential is already kinda...
... This is probably also a question of how big time-steps are chosen, and of the abstraction level. If the time-steps are big enough, the small positive...
Thanks for the replies. In response to your replies my question then is where are good starting places (i.e. web sites, pdfs, books possibly in my school's...
... This whole spiking neural networks thing is still quite new and there is no perfect introductory material available in my opinion. Books that I know of are...

... Of course, the weird errors in my text were just to make clear my point on anticipational mechanism. Bet you hardly noticed them since you anticipated what...
... Juha, thanks for those excellent posts on attention and anticipation. You are right on the money. It's strange that you and I are thinking about the same...
Louis, Another issue concerns the following questions: which sequence should be given priority over the others and can one sequence be pre-empted by another? ...
There is a well-known medical fact. Suppose someone hurt his toe. The pain draws his full attention. He jumps on one leg and accidentally trips a cofee pot on...
... Well, yes of course. I will have more to say on this in a coming news item on the site. Let me say for now that I don't think that a sequence, once...
... I like the thought that an item is a causally related train of thought. But did you mean that there would be seven sequences running on parallel at the...
... Yeah, this is probably true. I believe there is some mechanism which forces one's attention on this kind of emergency situation. But this attention only...
