Making decision in case-based systems using probabilities and rough sets

摘要

In knowledge-based systems, as particular systems for the making of decisions, the use of techniques to consider the uncertainty is of special interest. In this article, the problem of uncertainty is analysed in systems based on cases and a model that shows ways for its determination and handling using probabilistic techniques combined with concepts in the theory of the rough sets is proposed. The proposed model is based on a case-based structure, which allows a better retrieval of the cases. The ideas stated are explained through an example.
