Artificial Intelligence

Smart machines—those that can learn and make decisions autonomously—have become a reality. Artificial intelligence researchers in SRI's world-renowned Artificial Intelligence Center develop computer-based systems that exhibit intelligent behavior in complex situations. SRI's applied solutions solve problems, communicate with people in new ways, and interact with the physical world.

For commercial, industrial, and military clients, core artificial intelligence programs include
