... I would go further and include lossy compression tests. In theory, you could compress speech to 10 bits per second by converting it to text and using text compression. The rate at which the human brain can remember video is not much greater, probably less than 50 bps*. Therefore, as a goal, an AGI ought to be able to compress a 2 hour movie to a 45 KB file, such that when a person views the original and reconstructed movie on consecutive days (not side by side), the viewer will not notice any differences. It should be able to do this after training on 20 years of video. ...
I'm not convinced by this reasoning. First, the way individuals store audiovisual information may be differ, simply because of slight differences in brain development (nurture). Also, memory is condensed information about the actual high-level experience sensory/memory/whatsoever information, therefore very lossy. The actual 45kb memory of a movide is therefore quite personal to the subject. Recall of a photo/video is more like an impressionistic painting then the original. A perfect compression algorithm should compress subjective and much less lossy... A movie would be more then 45kb. It would be interesting to see how a human-ish compression algorithm would reconstruct a 45kb movie though :) ----- 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=231415&user_secret=fabd7936
