This paper presents an edge detection method based on morphological gradient technique and generalized type-2 fuzzy logic. The theory of alpha planes is used to implement generalized type-2 fuzzy logic. The proposed type-2 fuzzy edge detection method was tested with benchmark images to illustrate the advantages of the use of generalized type-2 fuzzy logic.
Following the concepts of Mpdf and J̃-plane, in this paper, the authors propose a new Type-2 Fuzzy Probabilistic System - Type-2 Fuzzy SARIMA System for real-valued uncertain non-stationary data-intensive seasonal time series forecasting. The system is implemented in Wireless Soft-Switch (WSS) communication network CAPS forecasting and is compared with the statistical model SARIMA to show that Type-2...
Modern organisations now collect very large volumes of data about customers, suppliers and other factors which may impact upon their business. There is a clear need to be able to mine this data and present it to decision makers in a clear and coherent manner. Fuzzy association rules are a popular method to identifying important and meaningful relationships within large data sets. Recently a fuzzy...
Selecting a suitable lighting level for reading is crucial to the overall success of reading comprehension. The light level preferences vary amongst the various users specifically according to changing environment conditions. Hence, there is a need to employ intelligent decision making systems which can consider the various preferences and criteria in order to achieve the convenience of the various...
General Type-2 Fuzzy Logic Systems (GT2 FLSs) are an extension to Type-1 (T1) FLS where at least one Fuzzy Set (FS) is a GT2 FS. However, due to the high computational complexity of operations on GT2 FSs, GT2 FLSs have been rarely used in practical applications. Instead, Interval Type-2 (IT2) FLSs which employ constrained IT2 FSs, have been widely used. Despite their superior computational complexity,...
How to design an interval type-2 fuzzy set (IT2 FS) from data has been a challenging issue till now. Mendel pointed that the centroid of an IT2 FS may be used as a measure of uncertainty to constraint its footprint of uncertainty (FOU) [1]. How to exact centroid from data has been studied in [1]; however, there exists no method to design an IT2 FS such that its centroid matches the desired one. To...
In this paper we introduce a Java based toolkit for the development of type-1, interval type-2 and (zSlices based) general type-2 Fuzzy Logic Systems (FLSs) which is available as a free download. We describe our motivation for the release of such a toolkit in Java - to improve the accessibility to specifically type-2 FLSs to users both in industry and academia beyond the fuzzy logic research community,...
