A New Fuzzy Time Series Forecasting Model with Neural Network Structure

Eren Bas and Erol Egrioglu

Abstract

Non-probabilistic forecasting methods are one of the most popular forecasting methods in recent years. Fuzzy time series methods are non-probabilistic and non-linear methods. Although these methods have superior forecasting performance, linear autoregressive models have better forecasting performance than fuzzy time series methods for some real-life time series. In this paper, a new hybrid forecasting method that contains stochastic approach based on an autoregressive model and fuzzy time series forecasting model was proposed in a network structure. Fuzzy c means method is used in fuzzification stage of the proposed method and also the proposed method is trained by using particle swarm optimization. The proposed method is applied to a well-known real-life time series data and it is proved that the proposed method has best forecasting performance when compared with some other studies suggested in the literature.
