―認識のためのT法―

抄録

Taguchi methods use patten information of each member of population such as photographs of many person or handwritten letters. This is quite different from diagnosis system or prediction of an earthquake. Because the latter has only one unit space and the S/N ratio is calculated from outside of unit. space called signals. Identification needs many unit space corresponding to each person or each letter. The method, Taguchi method for identification, uses distance within unit space to classify any other member outside the unit space. By using the new method to calculate the standerd S/N ratio and magnitude β for each member of unit space are calculated. Then final distance value of each member of unit space is calculated using Y₁ and Y₂

　　　Y₁=β

　　　Y₂=1/√η

Mean square of the distance is used to identify same similar members.
