摘要
对于一致决策表,基于D-S证据理论的知识约简与代数约简所得的结果是一致的,对于不一致决策表,它们并不完全一致.本文通过具体算例说明了基于D-S证据理论的广义决策约简与代数约简的在不一致决策表下的差异性,理论上证明了广义决策约简仅与分配约简是等价的,提出一种基于D-S证据理论求代数约简的方法.理论分析和算例都证明了本文方法的正确性.
For consistent decision table, the approach to knowledge reduction based on evidence theory is consistent with algebraic reduction. However, they do not comply with each other for inconsistent decision table. The difference between generalized decision reduction based on D-S evidence theory and algebraic reduction has been illustrated by an example. It is proved that generalized decision reduction is just equivalent to assignment reduction. A new approach to algebraic reduction based on evidence theory is proposed. Its validity is proved by theoretical analysis and an example is showed.
