Artificial Intelligence & Expert Systems

Artificial Intelligence

• “Computational intelligence is the study of the design of intelligent agents.”

• “An agent is something that acts in an environment—it does something. Agents include worms, dogs, thermostats, airplanes, humans, organizations, and society.”

• “An intelligent agent is a system that acts intelligently: What it does is appropriate for its circumstances and its goal, it is flexible to changing environments and changing goals, it learns from experience, and it makes appropriate choices given perceptual limitations and finite computation.” (Poole et al., 1998)
