Electroencephalogram (EEG) research has gained widespread use in various research domains due to its valuable insights into human body movements. In this study, we investigated the optimization of motion discrimination prediction by employing an artificial intelligence deep learning recurrent neural network (gated recurrent unit, GRU) on unique EEG data generated from specific movement types among EEG signals. The experiment involved participants categorized into five difficulty levels of postural control, targeting gymnasts in their twenties and college students majoring in physical education (n=10). Machine learning techniques were applied to extract brain-motor patterns from the collected EEG data, which consisted of 32 channels. The EEG data underwent spectrum analysis using fast Fourier transform conversion, and the GRU model network was utilized for machine learning on each EEG frequency domain, thereby improving the performance index of the learning operation process. Through the development of the GRU network algorithm, the performance index achieved up to a 15.92% improvement compared to the accuracy of existing models, resulting in motion recognition accuracy ranging from a minimum of 94.67% to a maximum of 99.15% between actual and predicted values. These optimization outcomes are attributed to the enhanced accuracy and cost function of the GRU network algorithm's hidden layers. By implementing motion identification optimization based on artificial intelligence machine learning results from EEG signals, this study contributes to the emerging field of exercise rehabilitation, presenting an innovative paradigm that reveals the interconnectedness between the brain and the science of exercise.
脑电图(EEG)研究因其对人体运动的宝贵见解而在各个研究领域得到广泛应用。在本研究中,我们通过在脑电图信号中特定运动类型产生的独特脑电图数据上应用人工智能深度学习循环神经网络(门控循环单元,GRU),研究了运动辨别预测的优化。实验涉及将参与者分为姿势控制的五个难度级别,目标是二十多岁的体操运动员和体育专业的大学生(n = 10)。应用机器学习技术从收集的由32个通道组成的脑电图数据中提取脑 - 运动模式。脑电图数据使用快速傅里叶变换转换进行频谱分析,并且GRU模型网络用于每个脑电图频域的机器学习,从而提高学习操作过程的性能指标。通过GRU网络算法的开发,与现有模型的准确率相比,性能指标提高了15.92%,实际值与预测值之间的运动识别准确率在94.67%至99.15%之间。这些优化结果归因于GRU网络算法隐藏层的准确性和成本函数的提高。通过基于脑电图信号的人工智能机器学习结果实现运动识别优化,本研究为运动康复这一新兴领域做出了贡献,提出了一种揭示大脑与运动科学之间相互联系的创新范式。
