Refining membership degrees obtained from fuzzy C-means by re-fuzzification
Fuzzy C-mean (FCM) is the most well-known and widely-used fuzzy clustering algorithm. However, one of the weaknesses of the FCM is the way it assigns membership degrees to data which is based on the distance to the cluster centers. Unfortunately, the membership degrees are determined without considering the shape and density of the clusters. In this paper, we propose an algorithm which takes th...
متن کاملSoil Property Mapping Using Fuzzy Membership Derived by Fuzzy c- Means (fcm) Clustering
This paper explores the use of fuzzy membership values generated by fuzzy c-means clustering (FCM) method to predict soil properties over space. A weighted average model was used on fuzzy membership to get soil properties. To validate the efficiency of this model, it was then compared with a multiple linear regression model between the soil property and terrain attributes. Four indices were cal...
متن کاملEstimating Membership Functions in a Fuzzy Network Model for Part-of-Speech Tagging
Part-of-Speech(POS) tagging is a process of assigning a POS to each word in a sentence. Since many words are often ambiguous in their POSs, POS tagging must be able to select the best POS sequence for a given sentence. Recently, probabilis-tic approaches have shown very promising results to solve such ambiguity problems. Probabilistic approaches, however, usually require lots of training data t...
متن کاملModeling proportional membership in fuzzy clustering
To provide feedback from a cluster structure to the data from which it has been determined, we propose a framework for mining typological structures based on a fuzzy clustering model of how the data are generated from a cluster structure. To relate data entities to cluster prototypes, we assume that the observed entities share parts of the prototypes in such a way that the membership of an enti...
متن کاملRepresenting Complex Fuzzy Membership Functions in a
The problem of deriving membership functions as a means for describing linguistic variables (for some control process) and the choice of fuzzy inference operators and connectives is at the heart of developing fuzzy control systems. Over the years con-nectionist systems have obtained prominence as a means to solve complicated learning tasks. More recently a surge in interest for applying neural ...
