Artificial Intelligence

• The study is to proceed on the basis of the
  conjecture that every aspect of learning or any
  other feature of intelligence can in principle be
  so precisely described that a machine can be made
  to simulate it.
• Mc Corduck 1979

5
Aims

• Produce on a computer, a pattern of output that
  would be considered intelligent if displayed by
  human beings.
• Program test of a particular theory of how a
  cognitive process might work.
• Strong AI the appropriately programmed computer
  is a mind.

Mechanics

• René Descartes (1596-1650)
• interested in automata that could simulate the
  human body
• non-human animals are like machines
• Julian Offray de la Mettrie (1747)
• the brain is subject to study and duplication
• Jacques de Vaucanson
• mechanical flute players, ducks

Intelligence

• Software versus Hardware Agents (robots)
• Agent
• Agency active behavior
• Rational actions
• Autonomy versus Control
• Cognition beliefs - desires - intentions (plans)
• Perception - Interpretation - Action
• Emotional Intelligence

Intelligence Problem solving

• Chess
• Measured as with IQ tests
• Solve Logic puzzles
• Learning
• Expert Systems medical diagnosis
• Knowledge of the world Cyc
• Drawing conclusions

18
Turing test (1950)

• I propose to consider the question Can machines
  think? This should begin with definitions of the
  terms machine and think.
• Instead of attempting such a definition I shall
  replace the question by another, which is closely
  related to it and is expressed in relatively
  unambiguous words.
• The new form of the problem can be described in
  terms of a game which we call the imitation
  game.

Idea

• The avatars in this version attempt to automate
  gaze and basic hand motion during a three-way
  conversation.
• The only input is the text typed by the users, no
  avatar control is needed.

43
Mechanism

• Touch the keyboard
• preparation for typing a message
• your avatar shows a "wanting-turn" behavior.
• Delivering the message,
• your avatar first looks away from listeners
  ("planning phase"),
• starts speaking and gesturing
• and then ends by looking at the next speaker.
• The next speaker is by default the one the user
  took the turn from.
• If another listener has indicated they want the
  turn in thE meantime, that user becomes the next
  speaker.
• If the current speaker expicitly names a person
  that is present, that person is offered the turn.
