I think your definition of "understanding" is in agreement with what Hutter calls intelligence, although he stated it more formally in AIXI. An agent and an enviroment are modeled as a pair of interactive Turing machines that pass symbols back and forth. In addition, the environment passes a reward signal to the agent, and the agent has the goal of maximizing the accumulated reward. The agent does not, in general, have a model of the environment, but must learn it. "Intelligence" is presumed to be correlated with a greater accumulated reward (perhaps averaged over a Solomonoff distribution of all environments). -- Matt Mahoney, [EMAIL PROTECTED]

And this doesnt cover the opposite of what other actions can be done, and what are the consequences, that is also important. And lastly this is for a "situation" only, we also have the more general case about understading a "thing" Where when it sees. or has, or is told about a thing, it understands it if, it know about general properties, and actions that can be done with, or using the thing. The main thing being we cant and arnt really defining "understanding" but the effect of the understanding, either in action or in a language reply. And it should be a level of understanding, not just a y/n. So if one AI saw an apple and said, I can throw / cut / eat it, and weighted those ideas. and the second had the same list, but weighted eat as more likely, and/or knew people sometimes cut it before eating it. Then the AI would "understand" to a higher level. Likewise if instead, one knew you could bake an apple pie, or apples came from apple trees, he would understand more. So it starts looking like a knowledge test then. Maybe we could extract simple facts from wiki, and start creating a test there, then add in more complicated things.

I'll grant that it's a bit fuzzy, but I believe that it captures the essence of the visible evidence of understanding. This doesn't say what understanding is, merely how you can recognize it. ----- 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/?list_id=303 _______________________________________ James Ratcliff - http://falazar.com New Torrent Site, Has TV and Movie Downloads! http://www.falazar.com/projects/Torrents/tvtorrents_show.php Sponsored Link Mortgage rates as low as 4.625% - $150,000 loan for $579 a month.
