Fuzzy Weighted Support Vector Regression With a Fuzzy Partition

IEEE Transactions on Systems, Man and Cybernetics, Part B (Cybernetics), 2007
The problem of the traditional support vector regression (SVR) approach, referred to as the global SVR approach, is the incapability of interpreting local behavior of the estimated models. An approach called the local SVR approach was proposed in the literature to cope with this problem.

Fuzzy information and optimal fuzzy partition

PeachFuzz 2000. 19th International Conference of the North American Fuzzy Information Processing Society - NAFIPS (Cat. No.00TH8500), 2002
The paper is devoted to the problem of measuring fuzzy information. Based on the extension of crisp stochastical approaches into fuzzy cases a concept and measure of the fuzzy information are proposed. Aspects of transferring the fuzzy information through fuzzy controllers using different fuzzy control models are also studied which allow us to ...

On External Measures for Validation of Fuzzy Partitions

2007
The procedure of evaluating the results of a clustering algorithm is know under the term cluster validity. In general terms, cluster validity criteria can be classified in three categories: internal, external and relative. In this work we focus on the external criteria, which evaluate the results of a clustering algorithm based on a pre-specified ...

Fuzzy Sets in Clustering: On Fuzzy Partitions

2019
Clustering is often classified as an unsupervised machine learning approach. It has been extensively used for data analysis. It permits us to extract some structure from a data set. Clustering can be applied to all types of data.

Fuzzy partitions and fuzzy-quotient rings

Fuzzy Sets and Systems, 1993
The cosets of a fuzzy ideal \(M\) in a ring \(A\) form another ring \(A/M\), called the fuzzy-quotient ring of \(A\) by \(M\). We show that \(A/M\) is always a fuzzy partition of \(A\), and a fuzzy partition of \(A\) will be a fuzzy-quotient ring (with respect to some fuzzy ideal) if and only if its associated fuzzy similarity relation is compatible ...

Fuzzy partition and fuzzy clustering

1986
Summary: In this paper necessary and sufficient conditions in which a fuzzy m- partition would make a fuzzy m-clustering of a sample set X were discussed. Further, on the basis of analyzing the clustering situation of a fuzzy partition we propose indexes for fuzzy clustering validity. Finally, fuzzy sets describing cluster were estimated.
