I have argued that text compression is just such a problem. Compressing natural language dialogs implies passing the Turing test. Compressing text containing mathematical expressions implies solving those expressions. Compression also allows for precise measurements of progress. Text compression is not completely general. It tests language, but not vision or embodiment. Image compression is a poor test for vision because any progress in modeling high level visual features is overwhelmed by incompressible low level noise. Text does not have this problem. Hutter proved that compression is a completely general solution in the AIXI model. (The best predictor of the environment is the shortest model that is consistent with observation so far). However, this may not be very useful as a test, because it would require testing over a random distribution of environmental models rather than problems of interest to people such as language. -- Matt Mahoney, [EMAIL PROTECTED] ------------------------------------------- agi Archives: https://www.listbox.com/member/archive/303/=now RSS Feed: https://www.listbox.com/member/archive/rss/303/ Modify Your Subscription: https://www.listbox.com/member/?member_id=8660244&id_secret=117534816-b15a34 Powered by Listbox: http://www.listbox.com
