Abstract

The invention provides a fatigue prediction method based on a Bayesian optimization XGBoost algorithm. The method comprises the following steps: 1, obtaining physiological signal data of a tester in amovement fatigue state through a signal collection instrument, and storing the physiological signal data; 2, eliminating abnormal data based on an RANSAC algorithm; 3, performing minority sample resampling by using an SMOTE oversampling algorithm to solve the class imbalance problem; 4, performing fatigue prediction by using the XGBoost model, and inputting the processed sample data into the XGBoost model for classification; and 5, optimizing the XGBoost model by using a Bayesian optimization algorithm. Through the above steps, a fatigue prediction process is realized, and the intelligence and accuracy of exercise fatigue recognition are improved.
