"Bits" is a perfectly sensible measure of information. Memory can be measured using human recall tests, just as Shannon used human prediction tests to estimate the information capacity of natural language text. The question is important to anyone who needs to allocate a hardware budget for an AI design. [For those not familiar with Richard's style: once he disagrees with something he will dispute it to the bitter end in long, drawn out arguments, because nothing is more important than being right.] -- Matt Mahoney, [EMAIL PROTECTED] ------------------------------------------- singularity Archives: http://www.listbox.com/member/archive/11983/=now RSS Feed: http://www.listbox.com/member/archive/rss/11983/ Modify Your Subscription: http://www.listbox.com/member/?member_id=4007604&id_secret=96140713-a54b2b Powered by Listbox: http://www.listbox.com
