The present application relates to a brain wave data processing method, device, equipment, medium and brain wave data processor. The method includes: obtaining the user's brain wave data; inputting the brain wave data into the self-associative memory neural network for prediction processing, and obtaining the Correction data, prediction and correction data include prediction correction values at different time points; brainwave data is input into the heteroassociative memory neural network for noise reduction processing, and the cumulative average brainwave data after noise reduction is obtained, and the cumulative average brainwave data after noise reduction The data includes the accumulated average value of brainwave signals after noise reduction at different time points; the predicted correction data and the accumulated average brainwave data after noise reduction are merged to obtain the merged brainwave data. The method respectively processes the acquired brain wave data through the self-associative memory neural network and the hetero-associative memory neural network, which can greatly reduce the noise in the brain wave data, and can further predict future brain wave data.
Description
technical field [0001] The present application relates to the field of computer technology, in particular to an electroencephalogram data processing method, device, equipment, medium and an electroencephalogram data processor. Background technique [0002] In the medical field, although there are currently strict policies and regulations to ensure the security and privacy of medical data, the growing network security risks still pose a threat to the security of medical data. The blockchain-based storage system uses distributed storage technology, and its built-in encryption technology can make the stored data not easy to be tampered with. Therefore, using blockchain technology for medical data storage can greatly improve data security, and storage The identity information of users who can access medical data. When a user wants to access medical data, the access operation can only be performed if the information logged into the system matches the stored identity information. ...
