Why and How to Learn Why: Analysis-Based Generalization of Procedures.
Computer learners often develop explanations of events they observe during training. Recent work on generalization suggests that explanations may be valuable in permitting learners to develop generalizations from one or a few examples. This study explores the idea by describing four generalization paradigms in which explanations play a part: explanation-based generalization (EBG), structure mapping analogical generalization (SMAG), modificational analogical generalization (MAG) and synthetic generalization (SG). It describes a model, the EXPL system, which is capable of applying MAG or SG to the generalization of simple procedures in human-computer interaction. It presents evidence that EXPL's analysis procedure, which constructs explanations as needed by MAG or SG, embodies heuristic principles used by human learners, and that MAG provides a good account of some human generalization, when retention of examples is not a problem.
