Below, Rodney Brooks sets up a de facto model of the development of intelligence - and it strikes me any such models are v. useful for AGI, for they suggest a natural order of levels in which any intelligence may have to learn about the world. Can anyone think of any similar models whatsoever, formal or informal, extensive or brief, over & above obvious candidates like Piaget & Kohlberg? And how does Ben's model of development for his AGI creations relate to such models?
Secondly, it would be interesting to discuss: does anyone think that there is no such thing - or almost no such thing - as development of intelligence? By definition, any agent must gradually build a body of data quantitatively.The issue is: does any intelligent agent have to build a world-picture, qualitatively, stage by stage? Starting say with simple objects and actions and comparisons, and moving to ever higher levels of classes of objects and actions and comparisons? OTOH if you do believe in a developmental approach to intelligence, why? My impression is that the logic of most AGI's can just as easily handle "China is attacking Japan" or "Countries often attack other countries" as "Jill is attacking Jack." http://www.spectrum.ieee.org/print/6307 "To appreciate the challenges ahead of us, first consider four basic capabilities that any true AGI would have to possess. I believe such capabilities are fundamental to our future work toward an AGI because they might have been the foundation for the emergence, through an evolutionary process, of higher levels of intelligence in human beings. I'll describe them in terms of what children can do. The object-recognition capabilities of a 2-year-old child. A 2-year-old can observe a variety of objects of some type-different kinds of shoes, say-and successfully categorize them as shoes, even if he or she has never seen soccer cleats or suede oxfords. Today's best computer vision systems still make mistakes-both false positives and false negatives-that no child makes. The language capabilities of a 4-year-old child. By age 4, children can engage in a dialogue using complete clauses and can handle irregularities, idiomatic expressions, a vast array of accents, noisy environments, incomplete utterances, and interjections, and they can even correct nonnative speakers, inferring what was really meant in an ungrammatical utterance and reformatting it. Most of these capabilities are still hard or impossible for computers.

Aaron Edsinger built Domo [left] to explore dexterous manipulation and visual perception. Mertz [right], created by Lijin Aryananda, is a robotic head able to learn from its environment. Cynthia Breazeal designed Kismet [center] to study human-robot social interactions. The manual dexterity of a 6-year-old child. At 6 years old, children can grasp objects they have not seen before; manipulate flexible objects in tasks like tying shoelaces; pick up flat, thin objects like playing cards or pieces of paper from a tabletop; and manipulate unknown objects in their pockets or in a bag into which they can't see. Today's robots can at most do any one of these things for some very particular object. The social understanding of an 8-year-old child. By the age of 8, a child can understand the difference between what he or she knows about a situation and what another person could have observed and therefore could know. The child has what is called a "theory of the mind" of the other person. For example, suppose a child sees her mother placing a chocolate bar inside a drawer. The mother walks away, and the child's brother comes and takes the chocolate. The child knows that in her mother's mind the chocolate is still in the drawer. This ability requires a level of perception across many domains that no AI system has at the moment." ------------------------------------------- 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=103754539-40ed26 Powered by Listbox: http://www.listbox.com
