On the use of generative deep neural networks to synthesize artificial multichannel EEG signals
This work addresses the need for synthetic EEG data in neural engineering, but it is incremental as it builds on existing generative deep learning methods.
The paper tackles the problem of generating artificial multichannel EEG signals by using conditional variational autoencoders to synthetically produce time-series signals that mimic spectro-temporal patterns expected during distinct motor imagery conditions, based on real resting-state EEG data.
Recent promises of generative deep learning lately brought interest to its potential uses in neural engineering. In this paper we firstly review recently emerging studies on generating artificial electroencephalography (EEG) signals with deep neural networks. Subsequently, we present our feasibility experiments on generating condition-specific multichannel EEG signals using conditional variational autoencoders. By manipulating real resting-state EEG epochs, we present an approach to synthetically generate time-series multichannel signals that show spectro-temporal EEG patterns which are expected to be observed during distinct motor imagery conditions.
