Evaluation on administrators of colleges and universities can provide a scientific basis for decision making on personnel assessment, selection, and appointment of cadres for organization departments. In talent evaluation process there are a number of vague concepts and various factors. Although we have the severity of the primary and secondary points, the ambiguity also exists between subjects and...
In majority of approaches of multi-attributes discretization, the results with a large number of break points always tend to make irrational and redundant. To this issue, this paper presents a dynamic multi-attribute algorithm based on rough set. This algorithm performs reduction to the attributes from the decision-making table through signification which generated by conditional entropy, then it...
Getting a better grasp of computer network security is of great significance to protect the normal operation of network system. Based on rough set (RS), clustering model, security features reduction and clustering algorithm are presented, which provides a basis of network security strategies. Further research is to mine and process the dynamic risks and management of network security. Using the reduction...
A kind of knowledge acquisition approach in decision-making system based on rough sets theory is proposed. In this paper the basic concepts and characters of rough sets is firstly overviewed. Then with decision attribute importance applied in decision-making system,the degree of dependency supplied by decision-making attribute for the condition attribute is described and the degree of attribute importance...
