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. |
