Detection of driver fatigue symptoms using transfer learning

This paper presents the results of the scientific investigations which aimed at developing the detectors of the selected driver fatigue symptoms based on face images. The presented approach assumed using convolutional neural networks and transfer learning technique. In the conducted research the pretrained model of AlexNet was used. The net underwent slight modification of the structure and then the fine-tuning procedure was applied with the use of an appropriate dataset. In this way all detectors of the selected fatigue symptoms were created. The results of conducted computations indicate that it is potentially possible to apply such an approach to the problem of fatigue symptom detection. The values of the overall misclassification rates for the most troublesome symptom are less than 5.5%, which seems to be a quite satisfactory result.
