A method for performing noninvasive blood glucose measurements was developed. The method is based on mid-infrared absorption spectroscopy and uses only a few wavenumbers to measure blood glucose levels unconditionally. We found that the regression of blood glucose levels using only three wavenumbers, which were selected using a series cross-validation technique, realized accuracies comparable to those of cases in which a greater number of wavenumbers are used. In addition, we demonstrated the performance of this model through correlations among different types of data.
开发了一种用于进行无创血糖测量的方法。该方法基于中红外吸收光谱,仅使用几个波数就能无条件地测量血糖水平。我们发现,使用仅三个通过系列交叉验证技术选择的波数对血糖水平进行回归,其实现的准确度与使用更多波数的情况相当。此外,我们通过不同类型数据之间的相关性展示了该模型的性能。
