Abstract

Provided are a method and an apparatus for removing individual differences in physiological signals, an edge computing device, and a storage medium. The method includes: acquiring physiological signals of a plurality of subjects, where the physiological signals are acquired by a physiological signal acquisition device when the plurality of subjects perform a same task; extracting frequency domain features based on the physiological signals, where the frequency domain features are configured to characterize frequency characteristics of the physiological signals; extracting cepstral features based on the frequency domain features; and normalizing the cepstral features to obtain cepstral features of the physiological signals with at least part of individual differences among the plurality of subjects removed. The method according to the present disclosure is beneficial to normalizing physiological signals, and removing individual differences in the physiological signals without restricting the data distribution of physiological signals, thereby having a wider range of applications.
