Introduction

Artificial Intelligence

AI attempts not just to understand but also to build intelligence entities.

What is AI?

Rationality

A system is rational if it does the right thing given what it knows.

Cognitive Science
Cognitive science brings together computer models from AI and
experimental techniques from psychology to construct precise and testable
theories of the workings of the human brain.

Agent

An agent is that acts. Computer agents are expected to have other
attributes that distinguish them from more programs such as operating under
autonomous control, perceiving their environment, persisting over a prolonged
time period, adapting to change and being capable of taking on another's
goals.

Rational Agent

Agent that acts to achieve the best outcome or when there is uncertainly,
the best expected outcome.

Four Categories of AI
(a) Systems that think like humans.
(b) Systems that act like humans.
(c) Systems that think rationality
(d) Systems that act rationally

(a) Systems that think like humans: The exciting new effort to make computers
think as machines in the full and literal sense.

(b) Systems that act like humans: The art of creating machines that performUcsy4u
functions that require intelligence when performed by people.

(c) Systems that think rationality: The study of mental facilities through the use
of computational models.

(d) System that act rationality: Computation intelligence is the study of the
design of intelligent agents.
