Research on the Improved ISODATA Clustering Algorithm Based on Entropy Weight Method

An objective weight method-entropy weight method is adopted to determine the item weight in syn- thetical performance evaluation in this paper.The entropy weight method is combined with the traditional fuzzy ISO- DATA clustering analysis method.The entropy weights are introduced into iterative formula for the target function of ISODATA,an improved synthetical performance evaluation algorithm is proposed based on the fuzzy ISODATA clus- tering and entropy weight.This algorithm is applied in the teachers'performance evaluation.The result is effective.
