APPARATUS FOR MEASURING BIOLOGICAL LIGHT

摘要

In automatically judging diseases of subjects from the characteristic wave patterns of changes in the hemoglobin level that are determined by measuring biological light, the separation of a group of healthy subjects from a group of unhealthy subjects and the separation of individual disease groups are improved. In an apparatus (10) for measuring biological light, an analysis section, wherein the wave pattern is analyzed, is provided with a judgment section (40) by which diseases are judged based on classification models. For conducting hierarchical classification, multiple classification models are provided in the judgment section. As the classification models, parameters obtained by synthesizing characteristic amounts of multiple kinds are employed. These classification models are optimized by the optimization method and automatically adjusted in association with changes in the data.
