30A-A-5 Scientific Analysis of the Flavor of Wine (I)(Biomedical Engineering Approaches to Human Senses and Errors)

抄録

A classification of famous wines is performed by three methods, i.e., cluster analysis method, principal component analysis, self-organizing map (SOM). The analysis is made based on the data taken from the review books on wines, which are expressed in terms of the various things around us using human sense of flavor. The results are reasonable, since three analysis methods give similar grouping in distribution of the wines except few cases. Especially red and white wines are separately grouped into the same kind of wine. The grouping as a result shows the expression of flavor using human sense is appropriate for the classification.
