脸谱法在卷烟风格特征中的应用

Application of Chernoff Face to evaluation of style characteristics of cigarettes

  • 摘要: 为了将卷烟感官评价数据直观、形象地表达出来,以便于评价人员更好地识别和应用感官评价结果,采用脸谱法(Chernoff Face)结合多维标度,对部分中式卷烟的风格特征评价数据进行分析,转换为易于被人识别的脸谱图,同时在多维度标度图中表达。结果表明,脸谱图中脸的大小、眼睛和嘴巴的形状等面部表情可以充分表达卷烟的风格特征,在多维度标度图中可以实现不同卷烟风格特征的相似性及差异性的直观识别,感官评价人员可以利用图形更好地掌握不同中式卷烟的风格特征,以有效地指导中式卷烟产品的开发和维护。

     

    Abstract: In order to express the sensory evaluation data of cigarettes visually and intuitively so as to better identify and use those evaluation results, Chernoff Face combined with multidimensional scaling method was used, the style characters of some domestic cigarette brands were analyzed. The evaluation data were converted into face graphs, which could be easily identified, those datawere expressed in multidimensional scaling plots at the same time. The results showed that the facial expressions, such as face size, shapes of eyes and mouth, could fully express the style character of cigarette. In the multidimensional scaling plots, the similarity and discrepancy between style characters of cigarette brands could be intuitively identified. This method will be helpful to sensory evaluators for knowing the characters of different cigarette brands and guiding the development and maintenance of cigarette products.
