Integrating a Portfolio of Representations to Solve Hard Problems
Susan L. Epstein · 2009
This paper advocates the use of a portfolio of representations for problem solving in complex domains. It describes an approach that decouples efficient storage mechanisms called descriptives from the decision-making procedures that employ them. An architecture that takes this approach can learn which representations are appropriate for a given problem class. Examples of search with a portfolio of representations are drawn from a broad set of domains. Representation and cognition A representation formally describes objects and their relationships, and provides ways to use them. In a complex domain, however, there may be many plausible representations for the same information about the search space and an agent’s position in it. Reasoning in such a domain may
