Case Based Reasoning Project for the class EEL 6876-Intelligent Diagnostics at UCF. Fall 2002

Introduction What is Case Based Reasoning? What is knowledge in CBR? Implementation issues in CBR

Case Based Reasoning Project for the class EEL 6876-Intelligent Diagnostics at UCF. Fall 2002

Problem Definition Given:

# Case Library of 21 cases# 7 test cases# Information about the domain

Develop a CBR System Using any Programming Language

Approaches Considered Use Domain Thresholds from

Handouts Extract rules from Case Library Pattern Matching and Thresholds Pattern Matching

Results To Prove Credibility of System test

with # Library Case# Sample case similar to Library Case

Test with given test cases

Library Case Results Chosen Library Case: Case #2 100% Match Closest Match: Library Case #2 Diagnosis: LEAK

Case Based Reasoning Project for the class EEL 6876-Intelligent Diagnostics at UCF. Fall 2002

Test case (like Lib. Case) Input parameters similar to Library

Case #2 95.3639 % Match Closest Match: Case #2 Diagnosis: LEAK

Adaptation Adaptation not used Possible, but needs expert help

during design time to ensure correctness

Conclusion Case Library dependent Better performance in Weak-theory

domains Simple Design Execution time Lack of Intuitive Knowledge
