Research interests
- My research investigates the role of experience and goals in focusing learning in complex domains. The ability to perform successfully in such domains depends on being able to recognize the need to learn and to select appropriate strategies for obtaining needed information.
- I am studying this goal-driven learning process in the context of computer programs whose search for information is guided by reasoning about current information needs and by their prior experience--both successes and failures--dealing with similar situations. The process that these programs use to apply their experience is case-based reasoning. Case-based reasoning systems maintain a memory of prior episodes and solve new problems by retrieving and adapting the solutions from those episodes. This process allows reuse of prior solutions while maintaining the flexibility to respond to changes in circumstances. I am investigating how goals direct the case-based reasoning process for both external and introspective learning.
