The ideal test set for text compression as a test for AI would be 1 GB of chat sessions, such as the transcripts between judges and human confederates in the Loebner contests. Since I did not have this much data available I used Wikipedia. It lacks a discourse model but the problem is otherwise similar in that good compression requires vast, real world knowledge. For example, compressing or predicting: Q. What color are roses? A. ___ is almost the same kind of problem as compressing or predicting: Roses are ___ Of course, the compressor would be learning an ungrounded language model. That should be sufficient for passing a Turing test. A model need not have actually seen a rose to know the answer to the question. I don't think it is possible to find any knowledge that could be tested through a text-only channel that could not also be learned through a text-only channel. Whether sufficient testable knowledge is actually available in a training corpus is another question. I don't claim that lossless compression could be used to test for AGI, just AI. A lossless image compression test would be almost useless because the small amount of perceptible information in video would be overwhelmed by uncompressible pixel noise. A lossy test would be appropriate, but would require subjective human evaluation of the quality of the reproduced output. For text, a strictly objective lossless test is possible because the perceptible content of text is a large fraction of the total content. -- 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=8660244&id_secret=49471493-636320

... or maybe they can be inferred from texts alone. It all depends on learning ability of particular design, and we as yet have none. Cart before the horse.

This is the age-old problem for AI. Either you have to build a physical system (a robot) which can in some sense experience the non-linguistic concepts upon which language is based, or you have to directly teach the system (enter a lot of common sense knowledge - the things we all know but which are rarely written down). - 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=8660244&id_secret=49226704-b6e4f3
