Cs3014: Artificial Intelligence introduction to artificial intelligence

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.
