Abstract

The invention discloses an electroencephalogram signal unmanned platform intelligent control method based on a deep convolutional adversarial network. The method comprises the steps that a terminal carries out the noise removal of a collected electroencephalogram signal, and obtains a denoised electroencephalogram signal; performing deep feature extraction on the denoised electroencephalogram signal through a capsule network to obtain a deep feature signal; fusing the deep feature signal and the electroencephalogram signal and then carrying out classification and recognition to determine a corresponding control instruction signal; and the terminal performs offline and online test verification on the unmanned platform, and after verification succeeds, the unmanned platform receives and executes the control instruction signal sent by the terminal. According to the method, the existing noise data are integrated into the one-dimensional electroencephalogram signal training network, the mathematical model is simplified, the problem of insufficient noise training data is solved, the one-dimensional prediction signal is reconstructed by using the auto-encoder architecture, the attention mechanism is used for feature selection, and the calculation efficiency is improved.

Description

technical field [0001] The invention belongs to the field of EEG intelligent control, and in particular relates to an EEG signal unmanned platform intelligent control method based on a deep convolutional confrontation network. Background technique [0002] The EEG signal is produced by the collective discharge of a large number of neurons in the cerebral cortex, which is the combined effect of a large number of neuron activities. Therefore, the EEG signal can be regarded as the superposition of various types of brain waves in different regions, composed of a large number of neurons. A complex composite wave formed by the electrical activity of a cell population. With the development of biosignal-related technologies, related research based on EEG signals has become a hot field. By exploring the relationship between EEG signals and brain nerves, people can discover the operating mechanism of the brain to express human intentions and movements, etc. Physiological information,...
