摘要: 由于目前没有一个评价羊毛衫领口性能的统一标准,应用领口拉伸测试仪对领口性能从耐用性和舒适性两个方面进行客观的分类,构建了样本隶属函数,用迭代的方法得到最优模糊划分系数,以最大隶属度原则对样本进行分类,最后应用FE和最大类间模糊划分熵检验分类的合理性和聚类的有效性。基于模糊划分的聚类方法有效减少了人为因素的影响并且提高了数据处理效率,其分类结果能为构建评价新样本的判别函数提供训练样本。

Abstract: Owing to the fact that uniform evaluation criterion of the neckline performance of woolen sweaters is not available presently,the performance of necklines of woolen sweaters is classified objectively by comfortableness and durability through testing the stretchability of the neckline.The membership function is constructed,and the optimal fuzzy division could be gained by iterative algorithm,then the samples are classified on the principle of the maximum membership grade,and finally the classification rationality and cluster validity are verified by FE index and the maximum value of fuzzy division entropy among kinds.By application of the cluster method based on fuzzy division,the effect of subjective factors is alleviated,and the effectiveness of data processing is improved.The classified samples could be the training samples for discriminate functions of new samples for evaluation system.
