Prerequisite: CS 580 or permission of instructor
This course presents the theory and practice of designing and developing systems that rely on expert knowledge and reasoning to solve complex problems in a specific (scientific, engineering, medical, intelligence, military, etc.) domain. Such an expert system or knowledge-based agent may assist a human expert in complex problem solving and decision-making, may be used by a non-expert user, or may teach problem solving and decision-making to a student. Capturing, using, preserving, transferring, and sharing knowledge is of critical importance to any organization as our society evolves from an information one to a knowledge one. Therefore, the ability to design and develop such expert agents for a wide variety of domains is a highly valuable expertise. The course covers both the basics of expert agents and knowledge engineering as well as advanced research topics. Basic topics include modeling expert reasoning, evidence-based reasoning, ontology design and development, knowledge acquisition and learning, knowledge base verification and validation. Advanced topics include discovery, mixed-initiative reasoning, agent teaching and multistrategy learning.
The students will learn about all the phases of building an expert agent and will experience them first-hand by using the Disciple development environment. Disciple has been developed in the Learning Agents Center (http://lac.gmu.edu) of George Mason University and has been successfully used to build expert agents for a variety of domains, including: intelligence analysis, military center of gravity determination, course of action critiquing, emergency response planning, teaching critical thinking, medical diagnosis, website evaluation, and PhD advisor selection.
The classes will consist of three parts: theory, tools and project. In the theoretical part, the instructor will present and discuss the various phases and methods of building an expert agent. In the second part the students will experience the use of advanced artificial intelligence tools for building expert agents. In the project part the students will design and develop an expert agent in a domain of their choice.
Students will have accounts on Blackboard and can download the lecture notes by going to courses.gmu.edu and logging in using their Mason ID and passwords.
The Disciple development environment is available only for Windows. If you have a Macintosh computer and want to install the software on it, you will have to use either a virtual machine or BootCamp to install Windows on your Macintosh computer. VMWare Fusion and Windows are available at no charge through your enrollment in Volgenau School courses. Instructions for obtaining the software are in the Microsoft DreamSpark & VMWare FAQs on http://labs.vse.gmu.edu
