I keep meaning to find some interesting podcasts and online lectures. There’s a ton of material out there, but so much of it sucks. Anyway, browsing the topic “What are the best Google Tech Talks” on Stackoverflow, I found the following, which I now link for your viewing pleasure:

XKCD visits Google – Very funny and interesting, but perhaps less enjoyable unless you’re an xkcd fanboy like me. Jump to 21:30 where xkcd answers a joking question from Donald Knuth.

PolyWorld: Using Evolution to Design Artificial Intelligence – An interesting A-Life experiment/visualization. Jump to 5:35 for some really neat video of an older program that evolves different body morphologies for efficient movement in a simulated physical environment. (I think this is the original work the speaker is citing)

The Next Generation of Neural Networks – The speaker flies through the intro material much too fast for me to understand with only a rudimentary knowledge of NN. Nevertheless, the demo at 21:35 is cool, as is the discussion around 31:40 of using these layered NN for document clustering and classification.
