Research on Prediction Algorithm of Employees’ Psychological Stress Based on Multifeature Fusion

Abstract

A multifeature fusion-based enterprise employee psychological stress prediction algorithm is suggested to address the concerns of low prediction accuracy, long duration, and poor results in current psychological stress prediction approaches. Examine ECG signal generation and properties, as well as the notion and causes of heart rate variability. The ECG signal is gathered according to the psychological stress reaction mechanism, and the digital filter is utilized to filter and preprocess the noise interference of the ECG signal. The linear discriminant analysis algorithm extracts the time domain linear features, frequency domain linear features, and nonlinear features of the ECG signal and then selects the ECG signal characteristics. D-S evidence theory is used to fuse the time domain linear characteristics, frequency domain linear characteristics, and nonlinear characteristics of the ECG signal, construct the psychological stress prediction model, obtain the final result of psychological stress state prediction, and realize the psychological stress prediction of enterprise employees, all based on multifeature fusion technology. The results of the experiments reveal that the suggested algorithm has a greater predictive effect on employee psychological stress, allowing it to enhance forecast accuracy and reduce prediction time.

“…There were no significant changes in heart rate and coronary flow between the two groups. The left ventricular diastolic blood pressure (LVDP) and rate overstock (RPP) in the physiological stress group and the psychological stress group were significantly lower than those in the control group ( P < 0.05), but there was no significant difference between the physiological stress group and the psychological stress group [ 1 , 2 ].…”
