APPLICATION OF NEURO FUZZY MODEL FOR FORECASTING CONSUMER PRICE INDEX IN YOGYAKARTA

摘要

The aim of this research is to predict the consumer price index (CPI) in Yogyakarta using neuro fuzzy model. The rule bases of neuro fuzzy model is constructed by tipe III, i.e. the consequent of fuzzy rules is linear combination of input variables. We apply the proposed method to predict CPI in Yogyakarta and the MAPE values of the model for training and testing data are 4.23% and 9.59%, respectively.
