【Abstract】 Feature attribute extraction of fault case is a very important aspect of fault case reasoning.The paper proposes the form of case decision table,introduces the attribute discretization algorithm of the Semi-Naive-Scaler,and also gives attribute reducing algorithm based on genetic.Based on these theories and methods of rough sets,the importance of feature attribute is calculated,and an example of attribute importance calculation is given at the end of this paper.更多还原
