How to Make Smarter Software
Forbes (03/19/08) Hardy, Quentin
Numenta founder Jeffrey Hawkins says artificial intelligence has come up short because it has concentrated too heavily on the results of the brain's operations without focusing on the general way those outcomes occur, and he is devoted to the development of unique software modeled after neocortical architecture and functionality in the hope that such an advancement will eventually lead to software and hardware that can truly emulate human intelligence. In 2007 Numenta released to developers an open-source version of software oriented around "hierarchical temporal memory," a theory formulated by Hawkins about how the human brain deals with incoming data. Hawkins says the brain is structured into a hierarchy of neuronal columns that absorb basic sensory input and sort it into patterns organized around time and space. The initial patterns are passed to more neurons that aggregate the information and feed it to more aggregators until the patterns become generalizations that lead to future projections. The Numenta software is designed to mimic this arrangement by forming a hierarchy of software nodes that seek to recognize patterns. Unlike neural network software, the Numenta software has no fixed number of levels because general topology and the use of time is altered with the desired outcome. It is Hawkins' hope that users will learn how to apply the software to the construction of smarter devices.
