Sandia Supported the Neuro-Inspired Computational Elements (NICE) Workshop in Albuquerque

July 26th, 2013|Categories: Capabilities, Materials Science, News, News & Events, Office of Science, Research & Capabilities|Tags: , , , , , , , , , , |

Retinal connectome The NICE workshop explored ways to use the brain’s superior ability to send electrical signals along massively parallel channels, with multiple intersections at downstream nodes, to handle rapidly changing, high-volume information. The hope is that rather than using the limited “if this, then that” logic of conventional computer architectures to absorb steadily increasing yet often incomplete data, cognitive systems will be able—like the brain—to learn, adapt, hypothesize, and then suggest answers.
