Goals of AI

  • To make computers more useful by letting them take over dangerous or tedious tasks from human
  • Understand principles of human intelligence

The Foundation of AI

  • Philosophy
    • At that time, the study of human intelligence began with no formal expression
    • Initiate the idea of mind as a machine and its internal operations

The Foundation of AI

  • Mathematics formalizes the three main area of AI: computation, logic, and probability
    • Computation leads to analysis of the problems that can be computed
      • complexity theory
    • Probability contributes the “degree of belief” to handle uncertainty in AI
    • Decision theory combines probability theory and utility theory (bias)

The Foundation of AI

  • Psychology
    • How do humans think and act?
    • The study of human reasoning and acting
    • Provides reasoning models for AI
    • Strengthen the ideas
      • humans and other animals can be considered as information processing machines

The Foundation of AI

  • Computer Engineering
    • How to build an efficient computer?
    • Provides the artifact that makes AI application possible
    • The power of computer makes computation of large and difficult problems more easily
    • AI has also contributed its own work to computer science, including: time-sharing, the linked list data type, OOP, etc.

The Foundation of AI

  • Control theory and Cybernetics
    • How can artifacts operate under their own control?
    • The artifacts adjust their actions
      • To do better for the environment over time
      • Based on an objective function and feedback from the environment
    • Not limited only to linear systems but also other problems
      • as language, vision, and planning, etc.
