Compression of iEEG Data
Seizure detection systems hold promise for improving the quality of life for patients with epilepsy that afflicts nearly 1% of the world’s population. High-resolution intracranial Electroencephalography (iEEG) enables the detection and location of such seizures. When aiming a low power implanted system the large amount of data has to be efficiently reduced. iEEG signals are sparse and have been successfully compressed using well-established encoders such as Discrete Wavelet Transform (DWT) or Non-Negative Matrix Factorization (NNMF) . Due to its recent success, however, convolutional neural networks (CNNs) are getting more attention and have shown to be a viable option to compress EEG signals . This project compares deep convolutional autoencoders with state-of-the-art DWT and NNMF to compress iEEG data from long-term recordings of epileptic patients. We use the publicly available long-term dataset  consisting of a total of 2656 hours iEEG recordings.
