ITCS 3153 Introduction to Artificial
Intelligence

• Dale-Marie Wilson, Ph.D.

Artificial Intelligence

• What is Artificial Intelligence?
• Artificial Intelligence is the area of computer
  science concerned with intelligent behavior in
  artifacts and involves perception, reasoning,
  learning, communicating, and acting in complex
  environments (Nilsson 1998)
• Artificial Intelligence is the study of ways in
  which computers can be made to perform cognitive
  tasks, at which, at present, people are better
  (Elaine Rich, Encyclopedia of AI)

Artificial Intelligence

• 4 categories of AI based on whether an agent
  thinks/acts humanly/rationally
• Goals of AI
• Develop machines that can do things just as good
  if not better than humans
• Understanding intelligent systems

4
Artificial Intelligence

• Main question in AI Can machines think?
• Are humans machines?
• Are other animals, insects, viruses, bacteria,
  machines?
• Can thinking only occur in special types
  (protein-based) machines (John Searle)? Chinese
  Room Argument
• Digital computer
• Storage
• Executive unit
• Control

Artificial Intelligence

• Main question in AI Can machines think?
• What does it mean to think?
• Turing Test Alan Turing (1950)

7
Artificial Intelligence

• Participants in Turing Test
• (A) a machine
• (B) a human
• (C) an interrogator

8
Artificial Intelligence

• Communicate with each other via a teletype
• Interrogators objective
• Identify X and Y Example X is A and Y is B
• As (the machine) objective
• Make the interrogator make the wrong
  identification
• Bs (the human) objective
• Help the interrogator make the correct decision

Artificial Intelligence

• Capabilities necessary to pass Turing Test
• Knowledge Representation Chapters 6 7
• Reasoning Chapters 9 10
• Learning (Adaptation) Genetic Algorithms
• Natural Language Understanding

Artificial Intelligence

• Capabilities necessary to pass Turing Test
• Computer Vision
• Robotics
• Computer Hearing
• Smell (Electronic Nose)
• Consciousness?
• Emotions?

11
Class Discussion

• Would evolution tend to result in systems that
  act rationally?
• What goals are such systems designed to achieve?

To Do

• Read Chapter 1
• Research Chinese Room Argument
