Well I wouldn't say it's obvious - it took me a good while to figure it out, after all :) Just true. Then again, AI is a hard problem; very few true things about it are obvious. > The human path to AGI is not > the only one. Oh indeed - as I said before, I'm not expecting anything like human-equivalent AGI in the foreseeable future. But I still think grounding is central for making useful AI programs. It's an example of the heuristic that applies to software in general: Internal computation is easy. Interfaces are most of the difficulty and most of the value. I don't _want_ to believe that, mind you. Internal computation is much more fun. But reality's rubbed my nose in itself on that one too many times for me to ignore. > 2) > I think that, potentially, building a KB could be part of an approach to > "solving the grounding problem."

But the key phrase is "Encode some simple knowledge, instruct the system in how to ground it in its sensorimotor experience" - i.e. you're _not_ spending a decade writing a million assertions and _then_ looking for the first time at the grounding problem. Instead grounding is addressed, if not as step 1, then at least as step 1.001. > My feeling is that sensorimotor grounding is an "Extremely Nice to Have" > whereas a KB is just a "Sort of Nice to Have", but I don't have a rigorous > demonstration of that.... Heck, I don't have a rigorous demonstration of any nontrivial fact about any program longer than ten lines, except that any working program provides a rigorous existence proof that the methods it used _can_ solve the problem it solves. ------------------------------------------- agi Archives: http://www.listbox.com/member/archive/303/=now RSS Feed: http://www.listbox.com/member/archive/rss/303/ Modify Your Subscription: http://www.listbox.com/member/?member_id=8660244&id_secret=95818715-a78a9b Powered by Listbox: http://www.listbox.com
