There are two interesting points here. The first is that (in my opinion) pattern matching must come first. I agree that understanding the patterns (the /why/) is important; but seeing (even unjustified) patterns is crucial. The benchmark I like to consider is an intelligent system being connected to a noisy camera for the first time. The noise may overwhelm the pattern matching at first, but over time it should automatically learn to filter out the noise regardless of whether or not it understands why the noise exists at all. The second interesting point is music. It is my belief that one of the important properties of music is how it tickles our pattern matching ability. Imagine a sequence of notes fed into an intelligent system (perhaps, through speakers into a human mind). The intelligent system automatically tries to find patterns in the notes such that it can model the notes (and predict subsequent notes). We can imagine another sequence of actions of the intelligent system as it parses subsequent notes in the music. These actions can indicate three things: - The note has been correctly predicted - The note has been incorrectly predicted and the system doesn't know why that note in particular was played - The note was incorrectly predicted, but it shows a new pattern which explains previously incorrectly predicted notes. It is my opinion that beautiful music makes an intelligent mind trigger 'just the right amount' of these second two kinds of modelling. -J ------------------------------------------- agi Archives: http://www.listbox.com/member/archive/303/=now RSS Feed: http://www.listbox.com/member/archive/rss/303/ Modify Your Subscription: http://www.listbox.com/member/?member_id=8660244&id_secret=103754539-40ed26 Powered by Listbox: http://www.listbox.com
