Re: [agi] What's the diff. between a simulation and a copy?
The difference is that a simulation is an approximation of a copy. Simulation code has to be complex because we want to preserve those features that are important, which is never a straightforward problem. An exact simulation of the universe down to the last particle would be a very simple program, probably a few hundred bits to specify the laws of physics. But it would require a computer larger than the universe to represent its quantum state (as a string of 10^122 bits). It would take even longer to run the simulation because the best known algorithms for computing the wave equations are exponential, or 2^(10^122) steps. So we approximate. -- Matt Mahoney, [EMAIL PROTECTED] - This list is sponsored by AGIRI: http://www.agiri.org/email To unsubscribe or change your options, please go to: http://v2.listbox.com/member/?member_id=8660244id_secret=80322602-300c67

Sorry about the delay, and Merry Xmas =) The goal is to provide an easy input for AGI, temporarily until full NL capacity is achievable. I guess most AGIers would have realized by now, that a separate NL module (such as a chart parser, even with statistical learning) would not work for AGI. The semantics of words, together with syntactic knowledge, should be integrated in one big KB, ie, generic memory. I'm planning ultimately to do that, but this is not happening immediately. That's why I want to build an interface that lets users provide grammatical information and the likes. The exact form of the GUI is still unknown -- maybe like a panel with a lot of templates to choose from, or like the autocomplete feature. It will be useful for logic-based / symbolic / hybrid AGIs.

I know this sounds like a dumb question, but Cyc has built a huge base of common sense knowledge in a structured format, but it isn't useful for anything. Of course that is not the result they anticipated. How will you avoid the same type of (very expensive) failure?

Re: [agi] NL interface
Matt, I agree w/ your question... I actually think KB's can be useful in principle, but I think they need to be developed in a pragmatic way, i.e. where each item of knowledge added can be validated via how useful it is for helping a functional intelligent agent to achieve some interesting goals... ben g What would you do with the knowledge base after you build it?

Re: [agi] NL interface
The problem with all traditional knowledge bases (CYC too) it is still all meaningless symbols for the processing computer program, processed according to relational rules in the KB, which are all entered by _human beings_. An AI would need to develop it's own KB, like a child - we all have our own little KB's in our brains, each developed individually be their education and experiences. The KB which the AI would learn would not make sense to us, of course; as little as the neural connections in a human brain make sense to us (in the sense of concepts).
