Williams Creativity Test B (WCTB) and Adolescent Scientific Creativity Scale (ASCS) were used to measure the creative affective and scientific creativity for 550 middle school students. In these students, 70% of them were used as modeling group, and the other as testing group. Generalized regression neural network (GRNN) and multivariable linear regression (MLR) were used for modeling and testing...
A intrusion detection system model based on particle swarm reduction was proposed in this paper. Though the experiment of this model, it turns out that the improved algorithm of quantum particle swarm can get the minimal reduction, improve particle convergence and make particles trapped into local minima more difficult. The algorithm is faster than GA and has a high rate of network intrusion detection.
In recent years, the competition between supermarkets is becoming increasingly fierce, and which urges all supermarkets to be constantly innovation in getting and maintaining their customers. In this paper, based on rough set data mining technology, the RFM model was applied to the classification of the supermarket customers, which provide decision support to enterprise marketing programs.
In order to improve the accuracy and the reliability of data mining of extension group decision-making by making comparison, selection and identification of objects under incomplete information, this paper studies extension classification, attribution reduction, rule extraction and data forecast of extension group decision-making based on combining extension transformation and group decision optimization...
Inspired by the theory of rough sets, this paper studies formal contexts from the viewpoint of approaximation operators. Firstly, a pair of approaximation operators are proposed based on a formal context, and the corresponding concept latices are constructed. Then, the relationship among these two lattices and the original concept lattice, the concept lattice of the complement of the original formal...
In order to solove the aero-engine maintenance level and costs optimization, it analyzed the practical monitoring performance data of aero-engine and proposed a method to mine maintenance decision-making rules by the rough sets theory. In the process of data mining, a self-organizing maps neural network(SOM-NN) was used to the continuous data discretization and obtained better effect. CF6-80C2A5 is...
Attribute Weight Determining (AWD) for multi-attribute evaluation and decision-making is a hot and difficult problem. According to the existing weight method based on rough sets having some deficiencies, A new measurement attribute importance and attribute weight determining methods are proposed on the basis of the literature review, which is discernibility matrix-based methods to determine the weight...
