Fever Time Series Analysis Using Slope Entropy. Application to Early Unobtrusive Differential Diagnosis. [PDF]
Entropy (Basel), 2020 Fever is a readily measurable physiological response that has been used in medicine for centuries. However, the information provided has been greatly limited by a plain thresholding approach, overlooking the additional information provided by temporal variations and temperature values below such threshold that are also representative of the subject ...
