To remove the redundant features extracted by using 2DPCA methods, a face recognition method is presented based on 2DPCA and fuzzy-rough technique in this paper. The proposed method selects the important features for classification by using attribute reduction in fuzzy rough sets theory. The experimental results show the proposed method outperforms the face recognition methods based on 2DPCA.
With respect to the aggregation problem of group decision-making based on ordinal preference information set, a processing method is proposed. The preference information is transformed into the educed matrix (fuzzy reciprocal judgment matrix) through quantifying ordinal preference information, it comes to conclusion that educed matrix is fuzzy reciprocal judgment matrix and the educed matrix meets...
A new early warning method of the complex systems for real estate market is proposed in this paper. First, principle component analysis method is adopted, and 8 important indexes are screened from a great number of indices. Second, these 8 important indices are divided into 3 kinds which are called as antecedent, synchronous and delayed with the time-difference correlation analysis method. Third,...
Based on the theories of social vulnerable groups and harmonious management, vulnerable groups in basin initial water right allocation are defined in the paper. According to their characteristics and allocation principle of initial water right, the evaluation index system of vulnerable groups is established. All the indexes weights are calculated on the basis of AHP, and the vulnerable grade is divided...
Many practical problems are characterized as decision making with multiple, conflicting and noncommensurable nonlinear objectives and complex criteria. For identifying these nonlinear function structure and multiple attributes is a very difficult, time consuming, and confusing job in multiple criteria decision making (MCDM). This paper presents a feedforward artificial neural network (FANN) as a flexible...
Fuzzy clustering is an important approach in data mining. It has been applied broadly in many aspects and receiving great attention from enterprisers and scholars. This paper makes use of MATLAB language to produce a fuzzy clustering algorithm for classifying electric power companies according to some general financial indexes at the end of 2006, such as ratio of operating income, ratio of stockholder's...
