In cluster analysis, certain features of a given data set may exhibit higher relevance than others. To address this issue, Feature-Weighted Fuzzy C-Means (FWFCM) approaches have emerged in recent years. However, there are certain deficiencies in the existing FWFCMs, e.g., the elements in a feature-weight vector cannot be adaptively adjusted during the training phase, and the update formulas of a feature-weight vector cannot be derived analytically. In this study, an Improved FWFCM (IFWFCM) is proposed to overcome these shortcomings. The IFWFCM-KD based on the kernelized distance is also proposed. Experimental results reported for five numerical data sets and the color images show that IFWFCM is superior to the existing FWFCMs. An interesting conclusion, that IFWFCM-KD might not improve the performance of IFWFCM, is also obtained by applying IFWFCM-KD to tackle the above-mentioned numerical data sets and color images. © 2014 Elsevier Inc.

In this paper, large sized polyhedron-like and plate-like Cr 2O3 were firstly obtained via hydrothermal synthesis under the assistance of the surfactant citric acid. The raw materials were K 2Cr2O7 and HCHO. With the increase of citric acid from 0.02, 0.05, 0.1, 0.12 to 0.16 g in sequence, morphologies of products changed accordingly. When it was 0.12 g and reaction temperature was 180 °C, polyhedrons with the size of 9-18 μm formed. With the increase of reaction temperature and keeping other reaction conditions the same, morphologies of products also changed obviously. When it was 240 °C, products were different sized plates from 5 μm to 106 μm made up of tiny particles. Influences of spatial effects and viscosity from amount of the added surfactant and reaction temperatures on the nucleation and diffusion rate lead to differences of stacking manners of precursor particles, and then lead to different morphologies of the products. Microstructures of materials were observed by a field emission scanning electron microscope and composition of products was investigated by X-ray techniques. © 2012 Published by Elsevier B.V.

With respect to multiple attribute decision making problem with triangular fuzzy linguistic information, in which the attribute weights and expert weights take the form of real numbers, and the preference values take the form of triangular fuzzy linguistic variables, a operator for aggregating triangular fuzzy linguistic variables, such as the fuzzy linguistic weighted harmonic mean (FLWHM) operator is introduced. Based on the FLWHM operators, a practical method is developed for group decision making with triangular fuzzy linguistic variables. Finally, an illustrative example about software selection is given to verify the developed approach.

With respect to multiple attribute decision making problems with linguistic information of attribute values and weight values, a decision analysis is proposed. Then, a method based on the ET-WA operator for multiple attribute decision making is presented. In the approach, alternative appraisal values are calculated by the aggregation of 2-tuple linguistic information. Thus, the ranking of alternative or selection of the most desirable alternative(s) is obtained by the comparison of 2-tuple linguistic information. Finally, a numerical example with risk evaluation of high-technology is used to illustrate the applicability and effectiveness of the proposed method.

The aim of this paper is to investigate the multiple attribute decision making problems with intuitionistic fuzzy information, in which the information about attribute weights is incompletely known, and the attribute values take the form of intuitionistic fuzzy numbers. In order to get the weight vector of the attribute, we establish an optimization model based on the basic ideal of traditional grey relational analysis (GRA) method, by which the attribute weights can be determined. Then, based on the traditional GRA method, calculation steps for solving intuitionistic fuzzy multiple attribute decision-making problems with completely known weight information are given. The degree of grey relation between every alternative and positive ideal solution is calculated. Then, a relative relational degree is defined to determine the ranking order of all alternatives by calculating the degree of grey relation to both the positive-ideal solution (PIS). Finally, an illustrative example is given to verify the developed approach and to demonstrate its practicality and effectiveness.

To improve the adaptability and effect of image enhancement, this paper has proposed an image enhancement method based on Gravitational Search Algorithm (GSA), which is used for optimizing the parameters of the normalized incomplete Beta function using the characteristics of the original image, the acquired function is employed to enhance the degraded image. The simulation results show the method can effectively enhance the global contrast of the image and vision. So this method is practical in the field of gray level image adaptive enhancement. © 2011 Published by Elsevier Ltd.

The aim of this paper is to investigate the multiple attribute decision making problems with linguistic information, in which the information about attribute weights is incompletely known, and the attribute values take the form of linguistic variables. We develop a new method to solve linguistic MADM with incomplete weight. In order to get the weight vector of the attribute, we establish an optimization model based on the basic ideal of traditional TOPSIS, by which the attribute weights can be determined. Based on this model, we develop a TOPSIS method to rank alternatives and to select the most desirable one(s). Finally, an example is shown to highlight the procedure of the proposed algorithm at the end of this paper.


This paper proposed an approach of mechanical failure information extraction and recognition in the early fault state variables, combined with the principal component analysis algorithm with FCM algorithm.

One of the most important decisions that has to be made by contractor firms is whether to bid or not to bid for a project, when an invitation has been received. For any construction company, being able to deal successfully with various bidding situations is of crucial importance, especially in today's highly competitive construction market. This paper presents an application of ant colony optimisation (ACO) algorithm and artificial neural network (ANN) to bid/no-bid decision making. The ACO algorithm is a novel heuristic bionic algorithm, which is based on the behaviour of real ants in nature searching for food. Neural network is used to express the nonlinear function between the input and output of the bid/no-bid decision making of project. ACO algorithm is used to learn ANN. The new algorithm has the merits of both ACO algorithm and neural network. The proposed decision support system framework is of good value to contracting organisations in different construction markets. Copyright © 2012 Inderscience Enterprises Ltd.

In this paper, we present an application of support vector machines (SVMs) and particle swarm optimisation (PSO) to fault diagnosis. SVMs have been successfully employed to solve regression problem of nonlinearity and small sample. However, the practicability of SVM is affected due to the difficulty of selecting appropriate SVM parameters. PSO is a new optimisation method, which is motivated by social behaviour of organisms such as bird flocking and fish schooling. The method not only has strong global search capability but also is very easy to implement. Thus, the proposed PSO-SVM model is applied to diagnosis operation of rolling bearing failure in this paper, in which PSO is used to determine free parameters of SVM. The experimental results also indicate that the SVM method can achieve greater accuracy than grey model, artificial neural network under the condition of availability of small training data.
