| Abstract: | The variable fuzzy clustering iterative model(VFCIM)was analyzed deeply.By comparing VFCIM and well-known ISODATA clustering iterative model with equal index weights,the rationality and convergence of VFCIM were demonstrated.At the same time,it is pointed out that the ISODATA clustering iterative model is a special case of VFCIM.An example is enumerated in the field of water resources,that is mid-long term runoff forecasting,which verifies the practicality of variable fuzzy clustering iterative model. |
