Abstract:
A blood glucose detection model training method, a blood glucose detection method and system, and an electronic device (900). The blood glucose detection model training method comprises: acquiring initial PPG data (f1, f2, f3,..., fN) comprising PPG data of healthy people (A1) and PPG data of people having blood glucose abnormalities (A2) (S101); acquiring the PPG data expressing different blood glucose levels as difference adjustment data (D1, D2, D3, D4) (S102); obtaining difference adjustment values (mf_D1, mf_D2, mf_D3, mf_D4) according to the difference adjustment data (D1, D2, D3, D4) (S104); performing difference amplification in initial PPG feature data corresponding to the initial PPG data (f1, f2, f3,..., fN) according to the difference adjustment values (mf_D1, mf_D2, mf_D3, mf_D4) so as to obtain model training PPG feature data (fa-mf_D1, fa-mf_D2, fa-mf_D3, fa-mf_D4) (S105); and performing model training according to the model training PPG feature data (fa-mf_D1, fa-mf_D2, fa-mf_D3, fa-mf_D4) to obtain the blood glucose detection model (S106). Since blood glucose information in the PPG data can be amplified differently using the difference adjustment data (D1, D2, D3, D4), the problems that blood glucose information in the PPG data is weak and extraction of blood glucose-related features is difficult are solved, and the blood detection result output by the blood glucose detection model obtained using the blood detection model training method is more accurate.
