I am talking about for machines, not for people. Obviously for humans, generation is harder because the evaluation problem has already been solved. For machines, this is a modeling problem. Once you have an algorithm for measuring the quality of a piece of art (movie, music, whatever), then producing art is just an optimization problem. You generate the art, evaluate it, make incremental adjustments and repeat. Generation is not technically difficult. Artists already use software tools such as synthesizers, animation software, video editors, etc. But we are nowhere close to solving the evaluation part. It is an extremely difficult problem, probably because it hasn't even been studied. We understand a lot about visual perception, speech recognition, and language modeling. But we understand practically nothing about what makes music sound good or what makes a joke funny. We just take it for granted that it requires a human brain in the loop. But really, I don't think this is any harder or easier than any other AI problem. (And I wouldn't underestimate the difficulty of music recognition). -- 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=4007604&user_secret=8eb45b07
