Case-Based Reasoning: A Research Paradigm

machines that can perform useful tasks. They want to develop the technology of intelligence. They want to be able to design and build computer programs that can solve problems and adapt to new situations. In this article, I discuss case-based reasoning, an AI paradigm that addresses both research agendas. Case-based reasoning is a psychological theory of human cognition. It addresses issues in memory, learning, planning, and problem solving. Case-based reasoning also provides a foundation for a new technology of intelligent computer systems that can solve problems and adapt to new situations. I first review the underlying psychological model of case-based reasoning. I then examine several “I have but one lamp by which my feet are guided, and that is the lamp of experience. I know no way of judging of the future but by the past.” —Patrick Henry Speech in Virginia Convention, Richmond March 23, 1775 There are two broad research agendas in AI. The first is scientific. AI researchers seek to understand the nature of intelligence and human thought. They examine a range of human cognitive behavior, including memory, learning, planning, and problem solving and look for principles that play general descriptive and explanatory roles. AI shares these scientific ambitions with other cognitive science disciplines. The second agenda for AI research is technological. Researchers seek to create Articles
