CS405: Artificial Intelligence
Unit 1: Introduction to Artificial Intelligence (AI) and AI Programming
While AI applications can be developed in any number of different languages, certain language features make programming AI applications straightforward. Prolog is structured in such a way that AI program development is supported by Prolog language features. Other languages, such as Java, support AI programming through code libraries. At this point in your career as a computer science major, you have already taken introductory programming courses; these should assist you in learning Prolog and using code libraries in other languages for AI program development.
This unit will provide you with an introduction to AI via programming features that support basic AI applications. By satisfying the goals of this unit, you will have a familiarity with AI programming and be able to use it in future models to implement various AI applications.
Completing this unit should take you approximately 10 hours.
Read these slides, which summarize the types and scope of AI applications and the state of the art in the field, as well as the early history of AI.
Read Chapter 1 on pages 1-4. AI concepts and techniques are learned in two steps: theory, and implementation of theory in programs. AI techniques are difficult to program and can be obscured by the programming details. To make these techniques explicit and to hide the programming details, AI languages, such as Lisp, Prolog, Scheme, and others, have been defined to have language features that directly support the implementation of AI techniques. The use of class libraries and source code libraries serve the same purpose for general-purpose languages, such as C++ and Java. The Watson text uses Java Classes for program examples of AI concepts and techniques. Java, being widely used, has the added advantage of making these techniques more widely available.
Read these slides on logic as a programming language. In declarative programming, you write statements that specify how to manipulate the data; that is, you write specific algorithms. In logic programming, you write statements that specify what is true of the world represented and rely on general-purpose algorithms that are built into the logic (programming) system.
