Compress Wikipedia and Win AI Prize
Baldrson writes "If you think you can compress a 100M sample of Wikipedia better than paq8f, then you might want to try winning win some of a (at present) 50,000 Euro purse. Marcus Hutter has announced the Hutter Prize for Lossless Compression of Human Knowledge the intent of which is to incentivize the advancement of AI through the exploitation of Hutter's theory of optimal universal artificial intelligence. The basic theory, for which Hutter provides a proof, is that after any set of observations the optimal move by an AI is find the smallest program that predicts those observations and then assume its environment is controlled by that program. Think of it as Ockham's Razor on steroids. Matt Mahoney provides a writeup of the rationale for the prize including a description of the equivalence of compression and general intelligence." -
Wolfram's New Kind of Science Now Online
gotscheme writes "When Stephen Wolfram of Mathematica fame self-published A New Kind of Science in 2002, he raised the suspicions of many in scientific communities that he was taking advantage of a lot of other people's work for his sole financial gain and that he was going against the open nature of academia by using restrictive copyright. Yesterday, Wolfram and company released the entire contents of NKS for free on the Web (short registration required). Perhaps Wolfram is giving back to the scientific community; perhaps it is simply clever marketing for a framework that is beginning to gain momentum. For any matter, the entire encyclopedic volume is online, and this appears to be a positive step for scientific writing." -
Facial Beauty and Fractal Geometry
Nick Moffitt writes "A Swiss Researcher wrote a program to generate "optimally beautiful" faces using "rotated squares and powers of 2". You can read his paper on the subject. " Maybe this is old, but I really dig this sort of stuff. I'm not so keen on the whole 'beauty' thing (artifact of looking like quasimodo :) but generate facial features is quite interesting. Worth a read.
