GPDC GRAPH CONVOLUTIONAL NEURAL NETWORK-BASED FATIGUE DETECTION METHOD, APPARATUS, AND STORAGE MEDIUM
Disclosed by the present invention are a GPDC graph convolutional neural network-based fatigue detection method, an apparatus, and a storage medium, wherein the method comprises: collecting initial brain electrical data; performing processing on the initial brain electrical data, and obtaining a first brain electrical signal; performing segmentation on the first brain electrical signal and computing a directed static network by means of generalized partial directed coherence; selecting important connection information from the directed static network, and, after performing binarization on the important connection information, obtaining a brain function matrix; constructing a directed brain function network by means of the brain function matrix; modeling extracted brain electrical features into graph signals by means of the directed brain function network; inputting a training graph signal into a graph convolutional neural network, performing network training and optimization, and obtaining a driver fatigue detection model; inputting a testing graph signal into the driver fatigue detection model, performing identification and detection, and obtaining a feedback result, thereby improving detection performance for a driving fatigued state.
Disclosed are a self-adaptive cognitive activity recognition method and apparatus, and a storage medium. The method comprises: collecting original electroencephalogram data; processing the original electroencephalogram data to obtain an electroencephalogram signal; respectively inputting the electroencephalogram signal into a state transition model and a reward model, so as to respectively obtain electroencephalogram state information and reward information; inputting the electroencephalogram state information and the reward information into a reinforced selective attention model to obtain optimal attention area information; and inputting the optimal attention area information into the reward model to obtain a classification recognition result. A cognitive activity can be recognized more effectively, and the recognition accuracy is also improved.
