Publication number: 20230230699Abstract: The invention provides a method for generating a training set of data for training a classifier relating to a physiological condition. The method begins by obtaining a first set of data relating to a first plurality of subjects and a second set of data relating to a second plurality of subjects, wherein each of the first set of data and the second set of data are grouped into a plurality of subsets of data, wherein the plurality of subsets of data is associated with a plurality of features. Descriptive statistics are calculated for each of the plurality of subsets of data within the first set of data and one or more features within the plurality of features is selected based on the calculated descriptive statistics to generate a search criterion. A supplementary set of data is identified from the second set of data by applying the search criterion to the second set of data. The training data set is then compiled based on the first set of data and the supplementary set of data.Type: ApplicationFiled: June 9, 2021Publication date: July 20, 2023Inventors: Sheng Jin, Xin Ge
