Based on abundant data of the civil servant performance appraisal systems home and abroad, the authors make comparison and analysis the Chinese and foreign systems, attempting to give an account of the advantages and disadvantages of China's civil servant performance appraisal system after summarizing the relevant appraisal indicators and evaluation methodology of the system in China. What are in...
A new image segmentation method based on three-dimensional fuzzy partition Renyi entropy was presented. First, on the basis of the theory of fuzzy partition, the fuzzy partition Renyi entropy was defined by using conditional probability and conditional entropy. ACO was used to obtain the optimal parameters to segmentation . The effectiveness of the proposed approach was demonstrated to real vision...
Aiming at the limitation of traditional graph-theory clustering method in the process of image segmentation, a new segmentation approach is proposed, which uses fuzzy similarity relationship to weight the edges while a complete graph is constituted. And fuzzy maximum spanning tree is used to clustering. Thus the traditional graph-theory clustering method is improved as the fuzzy graph-theory clustering...
There are internal and external reasons for the occurrence of landslip. Through the analysis on a large number of investigation materials of landslip, the growth inducements of landslip are found out. By use of theories in blur maths, we conduct order arrangement of these inducements in accordance their significance, put forward blur judgment rule of landslip estimation and present applicable examples.
Clustering is used to find out the objects that resemble each other and compose different groups, cluster analysis is an important job in data mining. This article brings the rough set into fuzzy cluster, by using the methods of attributes contracted in the rough set theory to improve the FCM algorithm; the improved algorithm had been proved a high precise ratio.
In the analysis of customer classification, redundant variables in the samples spoil the performance of the SVM classifier and reduce the recognition accuracy. On the other hand, we usually canpsilat label one customer as absolutely good who is sure to repay in time, or absolutely bad who will default certainly. In order to solve the problems mentioned above, this paper used rough sets (RS) as a preprocessor...
This paper proposes a new method of face image feature extraction, namely, the fuzzy inverse Fisher discriminant analysis (FIFDA) based on the inverse fisher discriminant criterion and fuzzy set theory. Experiments on the ORL and FERET face databases show that the new method outperforms the Fisherface and the inverse fisher discriminant analysis.
According to the WSEIAC (Weapon System Effectiveness Industry Advisory Committee) model, an index hierarchy of ground antiaircraft missile weapon system's effectiveness has been developed, and corresponding three hierarchy BP neural network was established. It is briefly concerned with the analysis of the BP algorithm, then through Delphi technique and the FAHP (fuzzy analytical hierarchy process),...
