Dissipative criteria for Takagi–Sugeno fuzzy Markovian jumping neural networks with impulsive perturbations using delay partitioning approach

Advances in Difference Equations, 2019
In this work, we investigate the result of dissipative analysis for Takagi–Sugeno fuzzy Markovian jumping neural networks with impulsive perturbations via delay partition approach. By using the Lyapunov–Krasovskii functional and delay partition approach,

An Alternative Estimation of Market Volatility based on Fuzzy Transform

, 2017
Realization of uncertainty of prices is captured by volatility, that is the tendency of prices to vary along a period of time. This is generally measured as standard deviation of daily returns.

A Study of Winning Percentage in the MLB Using Fuzzy Markov Regression

Mathematics
In this study, we analyze the winning percentage of 16 teams that have participated in Major League Baseball since 1901. First, 69 variables for each team are classified into pitching, batting, and fielding using factor analysis, and then the effect of ...

Clustering algorithms for fuzzy rules decomposition [PDF]

, 2007
This paper presents the development, testing and evaluation of generalized Possibilistic fuzzy c-means (FCM) algorithms applied to fuzzy sets. Clustering is formulated as a constrained minimization problem, whose solution depends on the constraints ...

Evolving Large-Scale Data Stream Analytics based on Scalable PANFIS

, 2018
Many distributed machine learning frameworks have recently been built to speed up the large-scale data learning process. However, most distributed machine learning used in these frameworks still uses an offline algorithm model which cannot cope with the ...

Propiedades de un enfoque difuso para particionamiento con datos bimodales

Revista de Matemática: Teoría y Aplicaciones, 2010
It is presented a new fuzzy partitioning criterion for two-mode data and an algo- rithm is formulated for its optmization. We study the convergence properties of the method. The method was tested on real data.

A Two-stage Classification Method for High-dimensional Data and Point Clouds

, 2019
High-dimensional data classification is a fundamental task in machine learning and imaging science. In this paper, we propose a two-stage multiphase semi-supervised classification method for classifying high-dimensional data and unstructured point clouds.

Agent-Based Product Configuration: towards Generalized Consensus Seeking [PDF]

, 2015
This paper will present an evolution of a fuzzy agent based platform which performed products configuration. As a first step, we used the notion of consensus to establish robust results at the end of the configuration process.
