Major Branches of AI
Perceptive system
A system that approximates the way a human sees, hears, and feels objects
Vision system
Capture, store, and manipulate visual images and pictures
Robotics
Mechanical and computer devices that perform tedious tasks with high precision
Expert system
Stores knowledge and makes inferences
Artificial Intelligence
The branch of computer science concerned with making computers
behave like humans. The term was coined in 1956 by John McCarthy
at the Massachusetts Institute of Technology. Artificial intelligence
includes
computer and talk to it. Unfortunately, programming computers to
understand natural languages has proved to be more difficult than
originally thought. Some rudimentary translation systems that
translate from one human language to another are in existence, but
they are not nearly as good as human translators. There are also
voice recognition systems that can convert spoken sounds into
written words, but they do not understand what they are writing;
they simply take dictation. Even these systems are quite limited --
you must speak slowly and distinctly.
Overview of Expert Systems
Explain their reasoning or suggested decisions
Display intelligent behavior
Draw conclusions from complex relationships
Provide portable knowledge
Expert system shell
A collection of software packages and tools used to develop expert systems
Knowledge Acquisition Facility
Knowledge acquisition facility
Provides a convenient and efficient means of capturing and storing all components of the knowledge base
