A fuzzy time series approach based on weights determined by the number of recurrences of fuzzy relations
(Elsevier, 2014)
Fuzzy time series approaches, which do not require the strict assumptions of traditional time series approaches, generally consist of three stages. These are called as the fuzzification of crisp time series observations, ...
Robust multilayer neural network based on median neuron model
(Springer, 2014)
Multilayer perceptron has been widely used in time series forecasting for last two decades. However, it is a well-known fact that the forecasting performance of multilayer perceptron is negatively affected when data have ...
PSO-based high order time invariant fuzzy time series method: Application to stock exchange data
(Elsevier, 2014)
Fuzzy time series methods are effective techniques to forecast time series. Fuzzy time series methods are based on fuzzy set theory. In the early years, classical fuzzy set operations were used in the fuzzy time series ...
An enhanced fuzzy time series forecasting method based on artificial bee colony
(Ios Press, 2014)
In recent years, several forecasting methods have been proposed for the analysis of fuzzy time series. Determination of fuzzy relations and establishing interval lengths, which is used in partition of universe of discourse, ...
Comparison of intraoral radiography and cone-beam computed tomography for the detection of horizontal root fractures: an in vitro study
(Springer Heidelberg, 2014)
This study aimed to compare the diagnostic accuracy of two different cone-beam computed tomography (CBCT) units with several intraoral radiography techniques for detecting horizontal root fractures. The study material ...
A high order seasonal fuzzy time series model and application to international tourism demand of Turkey
(Ios Press, 2014)
There have been many recently proposed methods for forecasting fuzzy time series. Most of them are, however, for non-seasonal fuzzy time series. A definition of seasonal fuzzy time series was firstly given by Song (Q. Song, ...
A modified genetic algorithm for forecasting fuzzy time series
(Springer, 2014)
Fuzzy time series approaches are used when observations of time series contain uncertainty. Moreover, these approaches do not require the assumptions needed for traditional time series approaches. Generally, fuzzy time ...
Fuzzy lagged variable selection in fuzzy time series with genetic algorithms
(Elsevier, 2014)
Fuzzy time series forecasting models can be divided into two subclasses which are first order and high order. In high order models, all lagged variables exist in the model according to the model order. Thus, some of these ...
Recurrent Multiplicative Neuron Model Artificial Neural Network for Non-Linear Time Series Forecasting [Proceedings Paper]
(Elsevier Science Bv, 2014)
Artificial neural networks (ANN) have been widely used in recent years to model non-linear time series since ANN approach is a responsive method and does not require some assumptions such as normality or linearity. An ...
