Again, do not confuse the two compressions. In paq8f (on which paq8hp5 is based) I use lossy pattern recognition (like you describe, but at a lower level) to extract features to use as context for text prediction. The lossless compression is used to evaluate the quality of the prediction. -- Matt Mahoney, [EMAIL PROTECTED]

And likewise with General Intelligence. I dont think under any of the many many definitions I have seen or created, that "text" or a compress "thing" can possibly be considered general intelligence. Another way: data != knowledge != intelligence Intelligence requires "something" else. I would say an actor. Now I would agree that a highly compressed, lossless data could represent a "good" knowledge base. Yeah that goes good. But quite simply, a lossy one provides a Better knowledge base, with two examples: 1. Poison ivy causes an itching rash for most people poison oak: The common effect is an irritating, itchy rash. Can be generalized or combined to: poison oak and poison ivy cause an itchy rash. Which is shorter, and lossy yet better for this fact. 2. If I see something in the road with four legs, and Im about to run it over, if I only have rules that say if a deer or dog runs in the road, dont hit it. Then I cant correctly act, because I only know there is something with 4 legs in the road. However, if I have a generalized rule in my mind that says If something with four legs is in the road, avoid it, then I have a "better" rule. This better rule cannot be gathered without generalization, and we have to have lots of generalization. The generalizations can be invalidated with exceptions, and we do it all the time, thats how we can tell not to pet a skunk instead of a cat.

Nevertheless, it is possible for us (being understanding systems) to know some of its features. I could produce a shopping list of typical features of understanding, but that would not be the same as a definition, so I will not. See my paper in the forthcoming proceedings of the 2006 AGIRI workshop, for arguments. (I will make a version of this available this week, after final revisions). 3) One tiny, almost-too-obvious-to-be-worth-stating fact about understanding is that it compresses information in order to do its job. 4) To mistake this tiny little facet of understanding for the whole is to say that a hurricane IS rotation, rather than that rotation is a facet of what a hurricane is. 5) I have looked at your paper and my feelings are exactly the same as Mark's .... theorems developed on erroneous assumptions are worthless.
