WiMi Hologram Cloud Inc. (NASDAQ:WIMI) has developed a new deep learning method for Brain-Machine Interface (BMI) signals with data enhancement. The method combines deep learning and data augmentation to generate a large amount of artificial EEG data using a small amount of EEG data, thus improving the accuracy and generalization ability of the classifier. The method also combines Convolutional Neural Network (CNN) and wavelet neural networks to better solve the data classification problem in the field of BMI.
