Polyworld: Using Evolution to Design Artificial Intelligence

Google Tech Talks November, 8 2007 ABSTRACT This presentation is about a potential shortcut to artificial intelligence by trading mind-design for world-design using artificial evolution. Evolutionary algorithms are a pump for turning CPU cycles into brain designs. With exponentially increasing CPU cycles while our understanding of intelligence is almost a flat-line, the evolutionary route to AI is a centerpiece of most Kurzweilian singularity scenarios. This talk introduces the Polyworld artificial life simulator as well as results from our ongoing attempt to evolve artificial intelligence and further the Singularity. Polyworld is the brain child of Apple Computer Distinguished Scientist Larry Yaeger, who remains the primary developer of Polyworld: http://www.beanblossom.in.us/larryy/Polyworld.html Speaker: Virgil Griffith Virgil Griffith is a first year graduate student in Computation and Neural Systems at the California Institute of Technology. On weekdays he studies evolution, computational neuroscience, and artificial life. He did computer security work until his first year of university when his work got him sued for sedition and espionage. He then decided that security was probably not safest field to be in and he turned his life to science.

How Evolution REALLY Works, Part I

How Evolution Works the GAME. A must see!!! KevinPluck has turned this simulation into an interactive game. You are the predator and the squares evolve to avoid you eating them. http://www.kevinpluck.net/evolution-versus-intelligence/ The world is full of misinformation. Interesting how most of the Young Earth Creationists and people pushing Intelligent Design, clearly don't have an education in the biological sciences. Evolution is the product of Natural Selection AND Mutation. Either alone does nothing. Evolution is the logical outcome of the world around us. Organisms that store their genetic information in DNA are guaranteed to have mutations. Mutations produce NEW variation. Reproducing organisms are guaranteed to compete for resources. Competition between variable organisms leads to natural selection, i.e. those organisms that possess variation that gives then an advantage will out compete those who don't. Organisms with deleterious variation will lose to all other organisms. In this way the ENVIRONMENT SELECTS the best organisms. This has the effect of passing beneficial mutations on to the next generation and removing deleterious ones. Over time natural selection will lead to a net shift in the genome of the population, i.e. evolution. Yes, this really is evolution. Changes in allele frequency, changes in gene expression, and changes in transcription factor binding efficiency, they are all evolution. Logic predicts evolution, and observation confirms it. Evolution has been observed in the lab and in nature. Speciation (macroevolution) has been observed in the lab and in nature. Large changes in appearance have been observed in the lab and in nature. Beneficial mutations have been observed in the lab and in nature. CORRECTION: Some have noted that Evolution need not include Natural Selection, as genetic drift does result in evolution. I agree that genetic drift is evolution, and should stress that Natural Selection is just one mechanism for evolution. Natural Selection + Random Mutation = Evolution Genetic Drift + Random Mutation = Evolution Both are true. To see an example of how genetic drift can lead to a speciation event, i.e. macroevolution, check out an old video of mine http://www.youtube.com/watch?v=Nnu-O5x_pRU To deny evolution is to deny direct observation. It is as silly as denying that the sky is blue.

Evolution IS a Blind Watchmaker

READ THIS In this video I deconstruct the broken watch straw man argument used by creationist / ID supporters to attack evolution. I had to pack a ton of information into this video so you WILL need to pause it periodically. The basic premise of the argument is that a bunch of parts will never randomly assemble into the correct arrangement to form a properly functioning complex. Once again, creationists / ID supporters miss the basic concept of evolution entirely. No biologists believes, nor is there any evidence that complex systems form spontaneously in one fell swoop. That would be creation. Systems evolve through many intermediates, one step at a time, slowly building up the complexity. Here I deconstruct their straw man argument. Basically, I simulate clocks as living organisms. Selective pressure is focused on their ability to accurately tell time. NO goal is imposed on the design (you can tell this because every simulation ends with a differently constructed clock). And it works. Clocks evolve through a series of transitional forms: Pendulum, Proto-clock, 1-handed Clock, 2-handed Clock, 3-handed Clock, and 4-handed Clock. Gradually the complexity is built up. These labels I have assigned to the transitional forms have nothing to do with the simulation itself. They are names I assigned so that we could analyze what the population was doing. The clocks are just clocks, living in their world, trying to tell time as accurately as possible. One thing I wanted to address but didn't have time in the video is how rapid the transitional period can be. In some simulations the population goes from pendulums to 3-handed Clocks in a hundred or so generations. And the transitions between the transitional forms are even more rapid, happening in about ten generations. Chances are none or a very limited representation of that transition will be preserved in the fossil record. One thing I should add. The program does not draw the clocks. It maintains, mates, and simulates them, but the drawing must be done manually from the genome matrix. The program is written in MatLab. The hand rotations that begin with 86 are 86,000 not 86.000. When YouTube compressed the video it becam hard to tell a comma from a period.
