    EEG Classification by Minimalistic Convolutional Neural Network Utilizing Context Information

  • Original language description

    Labelling of electroencephalography (EEG) or polysomnography (PSG) recordings can be time consuming for a physician (expert), especially if we consider long term monitoring (e.g. sleep stages). Convolutional neural networks (CNN), which use images created from raw or preprocessed data trials, appear to be a promising method for semi-automated label acquisition. To the best of our knowledge most of the existing studies use only one channel or a very small number of channels in combination with a complicated structure of the CNN. In our study we propose adding context information based on use of multiple channels in an input image. Based on our current understanding and state of the art we expect additional growth of final accuracy. Studies based on this approach show additional input from context information that enhances final validation accuracy. During our research we focused on small structure CNN with only three convolutional layers and two fully connected layers. Additionally, all methods which use CNN structure are heavily influenced by several parameters like number of classes or size of their convolution masks. Secondary goal of this study is to acquaint the reader with these parameters and with possible solutions for their problems. Based on more than six thousand different CNN settings and input settings we managed to acquire results up to 94.6% mean training accuracy and 88.2% mean validation accuracy in sleep stage classification on real PSG including sleep EEG recordings even with easy-to-create CNN structure.
