[IxDA Discuss] A MS Photosynth possibility

[Jon Strande]

Jeff (the Palm Pilot guy) Hawkins new company, Numenta, has developed a
cognitive computing program based on the research he shared in his book 'On
Intelligence'.

You can watch a presentation he gave at IBM Research's Almaden Institute
Conference on Cognitive Computing @ Google Video

You can see his Power Point Slides from the presentation here:

Basically the idea is that the Brain is pattern recognition and matching
organ, and that is what they're trying to deliver. The images that their
software recognizes are very rudimentary, but promising.
