Construction of the general Physical Condition judgments system by 2 (plane) and 3 (spherical) dimension SOM display

Abstract

The infrared optical source was shed on the fingertip and the intensity of the transmitted light or the reflection light was measured. The volumetric change of the bloodstream was estimated from these measurements. The acceleration plethysmogram wave data were obtained by the 2nd differentiation of the original measured waves. The results of the waves were classified by the Self-Organizing Maps (SOM) by 2-dimensional (plane SOM) and 3-dimensional (spherical SOM). The display of the clinical examples was also successful related to the Acceleration Plethysmogram Analysis.
