REEGNet: A resource efficient EEGNet for EEG trail classification in healthcare

Abstract

The architecture of REEGNet (Recurrent EEG Network) combines convolutional blocks from EEGNet with long short-term memory (LSTM) layers in order to improve temporal modeling capabilities. Additionally, the use of depthwise convolutions enables REEGNet to learn spatial filters specific to distinct frequency information. When evaluated on the exceptionally challenging IMAGENET configuration of the MindBigData Brain Dataset, consisting of 70,060 samples across 5 channels sampled at 128 Hz, REEGNet outperformed state-of-the-art models including EEGNet and LSTM architectures across all class configurations ranging from 2 to 40 classes. Specifically, REEGNet surpasses EEGNet by a margin of 10.6% in multi-class classification scenarios such as configurations with 10 classes, achieving an accuracy of 27.9%. These results highlight REEGNet’s potential to increase the accessibility of electroencephalography (EEG) analysis by allowing for reliable classification without extensive computational resources. This makes REEGNet uniquely suited for deployment in resource-constrained real-world environments and applications.
