Abstract：In modern life, high stress causes negative emotions and even leads to various chronic diseases. Psychologists need to understand the stress state of the individual in order to facilitate the corresponding psychological treatment. The traditional method of self-evaluation in psychology contains some subjectivity, while the method based on physiological polygraph can not be used in daily stress assessment because of the volume of equipment. For these reasons, a wearable device is used to collect the physiological signals and an assessment of the individual’s stress is made according to the associated relationship between the psychological and physiological. The Montreal Imaging Stress Task (MIST) is used to induce three states of no, moderate and high stress. The MIST includs both mental and psychosocial stress factors, which is more closing to a real-life condition. The experimental data are collected from 39 healthy subjects. Features are extracted from the data and the random forest is used to select the optimal stress-related feature combination, which is used to train and test the Support Vector Machine (SVM) classifier. Finally, the results show that the combination of random forest feature selection and SVM achieves a better performance. The accuracy is improved from 78% to 84% in the three states’ detection.
