Introduction of CBR p Recall the first time the car you drove. n n n p Manual Auto Nissan Toyota Dodge speedometer and tachometer Toyota Why can you drive so many cars that have different types of dashboard? S. H, Chou

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

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