Instructor's Manual Using Past History Explicitly as Knowledge: Case-based Reasoning Systems 9-1 45 Chapter 9 Using Past History Explicitly as Knowledge: Case-based Reasoning Systems Teaching Objectives Introduce the student to the concept of using explicit historical occurrences to solve current problems This is explained in the context of rule-based systems that also use past experience to solve current problems Introduce the student to case-based reasoning Introduce the student to how case-based systems can learn from their own experience Key Terms The following alphabetical list identifies the key terms discussed in this chapter. The page number for each key term is provided. Adaptation, p. 162 Case, p. 161 Case-based substitution, p. 168 Case library, p. 162 Critic, p. 172 Comfort factor indexing, p. 173 Evaluation, p. 167 Flat case libraries, p. 164 Learning, p. 169 Model-guided repair, p. 168 Parameter adjustment, p. 168 Problem space, p. 166 Remindings, p. 161 Retrieval, p. 166 Search, p. 168 Search-retrieve-propose, p. 167 Weak-theory domains, p. 175 Teaching Suggestions The important thing to get across to the undergraduate student is the mechanics of doing case- based reasoning: the components of a case-based system, such as retrieve, adapt, and learn. For a graduate student, it is additionally important to understand how historical knowledge is used explicitly, rather than “compiled,” as in the rule-based systems of the previous two chapters. The graduate student also needs to have an understanding of the advantages and disadvantages of CBR. This will permit the student to make decisions as to where it is applicable and where it is not.

Instructor's Manual Using Past History Explicitly as Knowledge: Case-based Reasoning Systems 9-2 45 Review Questions 1. List five general features common to applications that would be suited for solution through case-based reasoning. a) Historical cases must exist explicitly and be clearly documented. The documentation should preferably be in electronic form. b) Information on the historical cases should be complete and understood by human experts. c)
