There are a large quantity of non-certain and non-structure contents in the Web text at the present time. It is difficult to cluster the text by some normal classification methods. An algorithm of Web text clustering analysis based on fuzzy set is proposed in this paper, and the algorithm has been described in detail by example. The technique can improve the algorithm complexity of time and space,...
With the development of uncertain theory, fuzzy multi attribute decision making has been applicated in more and more areas. This paper established optimization model based on fuzzy ideal points for uncertain multi-attribute decision making problem in which the attribute values are given in the forms of triangular fuzzy number and the information on attribute weights is unknown completely or partly...
In the last decade, the use of artificial neural networks (ANN) has become widely accepted in medical applications for accuracy for predictive inference, with potential to support and flexible non-linear modelling of large data sets. Feedforward neural network (FNN) is a kind of artificial neural networks, which has a better structure and been widely used. But there are still many drawbacks if we...
In order to overcome the subjective limitation in existing evaluation methods, based on determination of the evaluation indicator weight by using rough set theory, a new fuzzy synthesized evaluation method of e-business website is proposed. It reduces subjective influence and increases the objectivity of evaluation result. An example shows the effectiveness and practicality of this evaluation method.
Peer-to-peer (P2P) eCommerce are commonly perceived as an environment offering both opportunities and threats. For peers to be effective they need some mechanism for managing this risk of failure. One way to minimize threats in such an open environment is to exploit reputation to help evaluate the trustworthiness of what and predict the future behaviors of peers. In this study, a set of parameters...
Image segmentation is an essential and important part in medical image processing. Conventional methods typically demand significant amounts of time and don??t lend to a natural interaction scheme with 3D volume. In this paper we present a novel interactive method for fuzzy connectedness segmentation. In our approach, the user freely specifies a seed point 3D location at regions of interest directly...
Fuzzy c-means (FCM) clustering algorithm is a popular model widely used in segmentation of magnetic imaging (MRI) data. The conventional FCM does not take into account the spatial information of image and get the unexpected results of segmentation when dealing with some MRI contaminated by noise. Considering the intensities of ideal MRI are piecewise constant, we present an improved model to fuzzy...
In this paper, the fuzzy concept based on T-implication operators is studied by the axiomatic approach. An operators-oriented characterization of the fuzzy concept is proposed, that is, the fuzzy intent-extent operator and the fuzzy extent-intent operator based on T-implication operators are defined by axioms. The axiom sets of the fuzzy concept operators guarantee the existence of fuzzy relations...
The implementation and application effect of e-commerce information system are important questions for manufacturing enterprise managers to care about. Based on the analyses of e-commerce information system in manufacturing, an integrated evaluation indices system is built up, which can be divided into 3 levels, 4 aspects, includes 20 detail indices. After the invited experts gave the relative important...
In most medical diagnostic systems, the numbers of cells, especially white blood cells, can be used to determine some diseases. Due to the complexity of microscopic blood images, the accuracy of white blood cell detection is still an active area of research. In most case, uncertainty is often happened while the images are under such conditions as backgrounds influence, cells reunion and occlusion...
Collaborative design is a new design style for mechanical manufacture. It can help designers of different places complete the same design project at the same time. It is an important problem to select a suitable partner for the collaborative design project from the partners. A fuzzy analytic hierarchy process (AHP) methodology is presented for the partner selection, which provide a multi-criteria...
E-commerce is one of the most important developments in Internet application. To be successful in the e-commerce marketplace organizations will need to provide high quality web sites that attract and retain users. Hence, evaluation methods for the effectiveness of e-commerce Web sites are a critical issue in both practice and research. The evaluation process involves human subjectivity and it is a...
