Fuzzy Time Series Forecasting Based On K-Means Clustering

Abstract

Many forecasting models based on the concepts of Fuzzy time series have been proposed in the past decades.These models have been widely applied to various problem domains, especially in dealing with forecasting problems in which historical data are linguistic values.In this paper, we present a new fuzzy time series forecasting model, which uses the historical data as the universe of discourse and uses the K-means clustering algorithm to cluster the universe of discourse, then adjust the clusters into intervals.The proposed method is applied for forecasting University enrollment of Alabama.It is shown that the proposed model achieves a significant improvement in forecasting accuracy as compared to other fuzzy time series forecasting models.
