不同聚类技术具有不同的原理和特征,需要对其进行比较优选。提出在铁路客运服务指标分析中,采用聚类效果测度系数方法,并将结果与基于列联表的公共信息方法相互印证,评价并优选聚类技术。实证分析表明,该评价方法简单易行,评价结果符合实际情况。 Different clustering techniques have different principles and features and need to be compared and optimized. In the analysis of railway passenger service index, the method of clustering effect measure coefficient is proposed, and the result is confirmed with the public information method based on contingency table, and the clustering technique is evaluated and optimized. Empirical analysis shows that the evaluation method is simple and easy, and the evaluation results are in line with the actual situation.
