A Hidden Markov Model-based Forecasting Model for Fuzzy Time Series

چکیده
Vague and incomplete data represented as linguistic values massively exists in diverse real-word applications. The task of forecasting fuzzy time series under uncertain circumstances is thus of great important but difficult. The inherent uncertainty involving time evolution usually makes the transition of states in a system probabilistic. In this paper, we proposed a new forecasting model based on Hidden Markov Model for fuzzy time series to realize the probabilistic state transition. We conduct experiments of forecasting a real-world temperature application to validate the better accuracy of the proposed model achieved over traditional fuzzy time series models.

In this paper, we propose a new residual analysis method using Fourier series transform into fuzzy time series model for improving the forecasting performance. This hybrid model takes advantage of the high predictable power of fuzzy time series model and Fourier series transform to fit the estimated residuals into frequency spectra, select the low-frequency terms, filter out high-frequency term...
