چکیده
In this paper, we present an algorithm to infer a fuzzy partition over a set of numerical values. This algorithm is based on the mathematical morphology and is expressed in the formal language theory. We use it during the construction of a fuzzy decision tree, in the case where no fuzzy partition is available for a numerical attribute. R esum e Dans ce rapport, nous pr esentons un algorithme pour construire une partition oue sur un ensemble de valeurs num eriques. Cet algorithme s'inspire des op erateurs de la morphologie math ematique pour d eenir des zones qui serviront de base a des sous-ensembles ous. Nous formalisons cette approche a l'aide de la th eorie des langages, sous la forme de syst emes de r e ecriture. Nous utilisons cet algorithme durant la construction d'un arbre de d ecision ou, pour trouver une partition oue pour un attribut a valeurs num eriques, quand aucune connaissance pr ealable sur cet attribut n'est fournie.

Fuzzy Partitioning Using Mathematical Morphology in a Learning Scheme
In this paper, we present an algorithm to infer a fuzzy partition over a set of numerical values. This algorithm is based on mathematical morphology and is expressed in theory of formal language. It is usable when the numerical values are associated with a class. We use this algorithm during the construction of a fuzzy decision tree, when no fuzzy partition is available for a numerical attribute.
متن کاملEvolutionary Design of Fuzzy Inference Systems by Means of Fuzzy Partition of Input Space
In this paper, we introduce the evolutionary design methodology of fuzzy inference systems by means of fuzzy partition of input space. The rules of the proposed fuzzy model are realized with the aid of the fuzzy partition of input space generated by fuzzy c-means clustering algorithm. The number of the partition of input space is equal to the number of clusters. And the individual partitioned s...
متن کاملNusselt Number Estimation along a Wavy Wall in an Inclined Lid-driven Cavity using Adaptive Neuro-Fuzzy Inference System (ANFIS)
In this study, an adaptive neuro-fuzzy inference system (ANFIS) was developed to determine the Nusselt number (Nu) along a wavy wall in a lid-driven cavity under mixed convection regime. Firstly, the main data set of input/output vectors for training, checking and testing of the ANFIS was prepared based on the numerical results of the lattice Boltzmann method (LBM). Then, the ANFIS was develope...
متن کاملEstimate Output of a Production Unit in Production Possibility Set with Fuzzy Inference Mechanism
In this paper, we consider the production possibility set with n production units such that the following four principles that governs: inclusion observations, conceivability, immensity and convexity. Our goal is to estimate the output of a same and new production unit with existing production possibility and amount of input is specified. So, initially we find the interval changes of each input...
متن کاملEvaluation of the Efficiency of the Adaptive Neuro Fuzzy Inference System (ANFIS) in the Modeling of the Ionosphere Total Electron Content Time Series Case Study: Tehran Permanent GPS Station
Global positioning system (GPS) measurements provide accurate and continuous 3-dimensional position, velocity and time data anywhere on or above the surface of the earth, anytime, and in all weather conditions. However, the predominant ranging error source for GPS signals is an ionospheric error. The ionosphere is the region of the atmosphere from about 60 km to more than 1500 km above the eart...
