Fuzzy classification of heart rate trends and artifacts
Dean Forrest Sittig, Kei-Hoi Cheung, Lewis E. Berman · 2003
Fuzzy set theory makes it possible to map inexact data, concepts, and events to fuzzy sets via user-defined membership functions. The authors describe a method for (1) robustly estimating the mean and slope of an arbitrary number of data points, (2) developing a set of fuzzy membership functions to classify various properties of heart rate trends, and (3) finding the longest consecutive sequence of heart rate data that fit a particular fuzzy membership function. Preliminary results indicate that fuzzy set theory has significant potential in the development of a clinically robust method for classifying heart rate data, trends, and artifacts.>
