Numenta's mission is to be a leader in the age of machine intelligence. Numenta believes that the brain is the best example of an artificial intelligence system, providing a roadmap for building intelligent machines. The core of brain intelligence--the neocortex--controls a range of functions. Numenta is trying to build a computer system that mimics the human neocortex, hoping to approach or outperform humans at many cognitive tasks. Numenta has developed several HTM (Hierarchical Immediate Memory) sample applications that demonstrate a wide range of applicable techniques and provide open source support for developers.
