標準化誤圧とMT法の特性と診断技術

－健康診断データを例として－

Among the computational methods used in the Mahalanobis-Taguchi system,the MT and RT methods are used for pattern recognition in classification tasks. Genichi Taguchi proposed the standardized variation pressure method five years before proposing the RT method, but while the standardized variation pressure method went largely unnoticed, when the RT method was presented it attracted much attention. To overcome the problem that the RT method cannot deal directly with data of different dimensions, data standardization was studied,leading to results equivalent to the variation pressure method. In this report, distances given by variation pressure and medical diagnoses derived from these distances will be described in comparison with the MT method. Diagnostic methods using variation pressure will also be mentioned.
