  1. Case-Based Reasoning Shih-Hsiung, Chou

  2. Outline • Introduction of CBR • Architecture of CBR • Ant Optimization • Backpropagation • Framework of ASCA-BP CBR model • Applications of CBR

  3. Introduction of CBR • Recall the first time the car you drove. • Manual Auto • Nissan Toyota • Dodge speedometer and tachometer Toyota • Why can you drive so many cars that have different types of dashboard?

  4. Introduction of CBR • How human beings solve problems? • by step-by-step instruction • by knowledge • by heuristic knowledge • You don’t know a reason; you can’t explain it • by memories • solve problem by past experience. (similarity cases) • This is what CBR wants to do • Memory-based problem-solving • re-using past experiences

  5. Introduction of CBR • Definition: • Case-based reasoning (CBR), broadly construed, is the process of solving new problems based on the solutions of similar past problems. [1] • Field[2]: • AI • Machine Learning • Data Mining • Expert System

  6. Architecture of CBR CBR Cycle[2] New Problem RETRIEVE Case Library Retained experience Retrieved cases REUSE Solution Domain Retrieved Solutions RETAIN Revised solution REVISE
