A Clustering Method forOrdering Samples and Its Utilizationin Study of Farm Mechanization Level
Abstract:
A clustering method for the ordering samples is discussed based on the dynamic programming. It can be used to identify the breaking points and divide the sample into some sub-samples at where there are significant differences between the neighbor sub-samples, and obtain the optimum clustering results under a certain criterion. This method has been used in the evaluation of farm mechanization levels of different provinces in China. The results proved that this method is practical.
