Alternative Fuzzy Switching Regression
Kuo-Lung Wu, Miin‐Shen Yang, June-Nan Hsieh · 2009
Abstract—This paper present an alternative method for fuzzy switching regression analysis. The traditional fuzzy c-regression (FCR) is a method by embedding the fuzzy c-means (FCM) into switching regression. By defining an alternative residual measurement, we modified the fuzzy c-regression (FCR) and proposed an alternative fuzzy c-regression (AFCR). The proposed method is more robust to noise and outlier than the EM and FCR algorithms. Numerical examples show the robustness and superiority of our proposed method.
