Analysis of pulse diagnosis data for the elderly by using two analytical methods. (6th August 2019) - Zhou, Siyu
The use of information and communication technology (ICT) to analyse pulse diagnosis data has become one of the pathways of modernising traditional Chinese medicine (TCM). In this study, we used two methods of medical statistics and machine learning to analyse diagnosis data. We used the Youden index to evaluate the authenticity of the diagnosis and the Kappa statistic to evaluate the consistency of the diagnosis made by the pulse diagnosis instrument and the TCM doctor. The accuracy of a single pulse was almost 80%. The authenticity and consistency were acceptable. The k-NN method was used to match the diagnosis results of the pulse diagnosis instrument and the TCM doctor. The overall accuracy rate was 62%, similar to that in previous studies. In practice, medical statistical methods (Youden index and Kappa statistic) are used to determine the accuracy of a single pulse, and machine learning methods (k-NN method) are used to classify pulse matching.
