Artificial Intelligence

1. What is AI?

   • Acting Humanly
     • The Turing Test Approach
       • A computer passes the test if a human interrogator cannot tell whether the written responses come from a person or from a computer
         • The computer would need:
           • Natural language processing
           • Knowledge Representation
           • Automated Reasoning
           • Machine Learning
         • The computer will need:
           • Computer Vision
           • Robotics
   • Thinking Humanly
     • The Cognitive Modeling Approach
       • Brings together computer models from AI and experimental techniques from psychology to construct precise and testable theories of the human mind
   • Thinking Rationally
     • The ¨Laws of Thought¨ approach
       • Focuses on employing formal rules of logic and reasoning, inspired by principles laid out by philosophers such as Aristotle, to guide intelligent decision-making processes within AI systems.
   • Acting Rationally
     • The Rational Agent Approach
       • Focuses on designing intelligent systems that make decisions to maximize expected utility based on their knowledge and goals, embodying rationality in their actions.

     • What can be computed?
     • How do we reason with uncertain information?
   • Economics
     • How should we make decisions to maximize payoff?
     • How should we do this when others may not go along?
     • How should we do this when the payoff may be far in the future?
   • Neuroscience
     • How do brains process information?
   • Psychology
     • How do humans and animals think and act?
   • Computer Engineering
     • How can we build efficient computers?
   • Control Theory/Cybernetics
     • How can artifacts operate under their own control?
   • Linguistics
     • Hoe does language relate to thought?
