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.

HAHAHA, APPLE FAIL! Even Vista coulda pulled that off!

Sure, the whole number eigen values of the hamiltonian express the basic states of quanta in 3d1t space and it builds up from there. Granted I don't have a DS, but I would still say we have a pretty good understanding of the math involved at that level. Human ai isn't special, especially if you watch Jerry Springer.

Interesting. My hunch is that the relationships are there, but it's a matter of scale. We don't know enough about really small things or really big things to see the realtionships clearly. I seem to remember reading about the use of hamiltonians to achieve some insight into quantum systems. In any case, I like the comment. I give it six points.

yeah "Something like... "uhm... so, yeah! uhm... now, uhm... something like that." :P" but hes really good.. he has done alot

I suppose more complex interactions with not only the environment, but with users, and other agents(AI forms?) can be incorporated later on. As he said mid presentation, this is the raw of the raw. Thanks for the presentation, this was informative and thought provoking, I have a lot of questions, and theories on the subject.

Does that mean that AI can't form relationships or base their decisions on incoming situations that may effect others around them, the sole purpose is self preservation, but sometimes in life we have to sacrifice for the greater good, this ability defies his rule of energy conservation.

Cause and effect? so if someone attacks you(cause) you have the option to run or fight for survival (effect?)

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.
