>>>>>>>>>>>>>>>>>>>>>>>>> The two AGI modes that I believe people use are 1) mathematics and 2) experiment. Note that both operate in restricted domains, but within those domains they *are* general. (E.g., mathematics cannot generate it's own axioms, postulates, and rules of inference, but given them it is general.) Because of the restricted domains, many problems can't even be addressed by either of them, so I suspect the presence of other AGI modes. Possibly even slower and more expensive to use. I suppose that one could quibble that since the modes I have identified are restricted to particular domains, that they aren't *general* intelligence modes, but as far as I can tell ALL modes of human thought only operate within restricted domains. <<<<<<<<<<<<<<<<<<<<< AGI which only operates in restricted domains is no AGI as I understand it But it seems to be, that I use this term in a much stronger sense than most other people. I assume that most people understand AGI as human-like intelligence which refers especially to the repertoire of tasks which can be solved. As I said, 'true AGI' does not use any bias. But any powerful intelligence must use bias because real world state spaces are too complex for 'true AGI'. So AGI as it is used commonly is only approximated and limited AGI but of course much broader than AI of the present and the past. I follow some other people that human-like AGI will probably be build by several narrow AI algorithms that work together. Humans uses and create object oriented descriptions of the world similar to the paradigms of object oriented programming Languages. This paradigm is very powerful in many domains because the inner structure of these domains are in fact object-oriented. But this does not hold in all domains. Among other advantages the object oriented paradigm helps humans to make useful generalizations. For example: A television is a electric appliance. Electric appliances need electric energy. So if there will be some new electric appliance in the future I already know that it will only work if it gets electric energy. On the other hand, the object oriented paradigm is poor for recognition of sounds and voices. We can hardly describe the voice of a person as a set of classes and objects which have some properties, behavior and interact with each other. So the object-oriented paradigm is an example for a very general paradigm but which is not 100% useful in all domains. And the brain has probably not a general monolithic algorithm which finds regularities at all levels. The recognition of regularities in sounds is surely not solved by the same algorithm which learns that houses have windows. The brain even changes its architecture to some degree during lifetime. A baby brain has far more synapses than an adult brain. I think during the first years humans extend their bias which they have from your genes. When they are older, humans can solve many problems but they rely on the bias they obtained during childhood and from their genes. By the way, there is a nice analogy between the brain and the universe: You can't explore your past processes of your own mind of the very first day of your life because your brain changed its inner structure in the first years too much and the algorithm for object oriented patterns probably did not yet exist at that time. The whole universe also will not be able explore its past processes of the big bang. At that time the inner structure changed. There were no atoms, light was scattered always and everywhere. Therefore, we and any possible machine of the universe can only see events some 100000 years after the big bang when there were already atoms. ------------------------------------------- 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=101455710-f059c4 Powered by Listbox: http://www.listbox.com
