On the basis of analyzing and creating the index system of the fault evaluation of certain new weapon system power vehicles, Delphi was used to distribute weight vectors, and fuzzy comprehensive assessment model was given out. A sample shows that the model is practical, as well as the model can be used in various weapon systems and the relevant software can be developed by the professionals. It offers...
Human is the focus of knowledge discovery. The user can express his focus via constraints in mining. However, constraints specified by the user are often fuzzy. The paper proposes the notion of fuzzy constraints and develops techniques to introduce these fuzzy constraints into the Apriori algorithm for mining frequent itemsets. The experiment results show the effectiveness of the improved techniques
