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/l... 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.

Nuclear decay does not have to be cause-effect induced. A particular atom may decay now or wait 14 billion years. Arguably perhaps we don't know how to define the atom well enough to prove rigorously that it is also cause-effect grounded. There are other examples along these lines that involve "quantum decisions".

Agreed... his delivery was very jittery and not flowing... which leads to his speech requiring excessive concentration.

Its like he fears for his life...does Google make people do speeches at gunpoint?

Smart guy, needs to work on his speeches. Slow down... dude. ^_^ Other then that, understandable

Very nice video, though yeah he seemed nervous, he was perfectly understandable. I would like to see a day where game AI could have "human like" thinking.

Agreed.

Subtitles would be helpful.

very very interesting . this brought a new viewing lense (perspective) on how i have always viewed artificial intelligence. This is REALLY really, alluring. I should look into studying it.

Can anyone (including intelligent designers) come up with an example of ANYTHING that is NOT a cause-effect product? And isn't that what evolution really is? From that perspective, don't we use evolution in design, no matter what approach we take? I'm being a smart-ass... sorry. Interesting vid.

The cost function is there to mimic real physical constraints. Animals, in the real world, need to eat something in order to survive...
