Abstract: With the development of society, people increasingly demand for data prediction, fuzzy time series has been attracted much attention because it can handle the ambiguities in time series data. To improve the prediction accuracy of the model, domain partition is crucial as the first step of the prediction. In this paper, we present a FCM-based two-time domain partition method. We make the first partition according to the clustering center obtained from FCM clustering, the second partition to realize unequal domain according to the density distribution of the sample points. Finally, the feasibility of the new method is verified through the prediction of classic sample.
