Cutting-Edge AI Projects?

Xeth writes "I'm a consultant with DARPA, and I'm working on an initiative to push the boundaries of neuromorphic computing (i.e. artificial intelligence). The project is designed to advance ideas all fronts, including measuring and understanding biological brains, creating AI systems, and investigating the fundamental nature of intelligence. I'm conducting a wide search of these fields, but I wanted to know if any in this community know of neat projects along those lines that I might overlook. Maybe you're working on a project like that and want to talk it up? No promises (seriously), but interesting work will be brought to the attention of the project manager I'm working with. If you want to start up a dialog, send me an email, and we'll see where it goes. I'll also be reading the comments for the story."

I think the Deep Belief Networks of Hinton et al are way ahead of Numenta.. in that they are real science with measurable results that has been reproduced by multiple implementations. The 2006 paper that started it all and Hinton's presentation on google video:

A formal analysis:

Application to natural language processing:

Reproducing Hinton and extension to and evaluation in other domains:

Use in Computer animation of facial expressions:

Most impressive:

A C++ implementation (although it has much Python love):

So yeah, there's some pretty good demonstrations of how powerful DBNs are.. Numenta is lagging behind.
