摘要: |
基于动态规划思想提出了一种有序样本的分类方法,能够识别子样(分段)间的分点,接问题的需要将整个样本划分成不同子作,使整个分类达到某种目标下的最优。应用于农业机械化发展水平的分类研究,取得了与实际情况一致的效果。 |

A Clustering Method for Ordering Samples and Its Utilization in 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. |
