Noninvasive Blood Pressure Classification Based on Photoplethysmography Using K-Nearest Neighbors Algorithm: A Feasibility Study

Abstract: Blood pressure (BP) is an important parameter for the early detection of heart disease because it is associated with symptoms of hypertension or hypotension. A single photoplethysmography (PPG) method for the classification of BP can automatically analyze BP symptoms. Users can immediately know the condition of their BP to ensure early detection. In recent years, deep learning methods have presented outstanding performance in classification applications. However, there are two main problems in deep learning cl… Show more

“…In ref. [12], Tjahjadi and Ramli propose a method to classify BP by means of the K-nearest neighbors (KNN) algorithm based on PPG. The data are related to 121 subjects, who are divided into normotensive, pre-hypertensive, and hypertensive.…”

“…This means we consider the discrimination ability provided by an algorithm at different levels of granularity into which the data set can be divided, as reported in, e.g., refs. [4,11,12]. This analysis allows us to ascertain which is the best machine learning algorithm.…”
