Abstract

Electroencephalogram (EEG) data compression has been used to reduce the space for storage and speed up the data circulation. Albeit lossy compression techniques achieve a much higher compression ratio than lossless ones, they introduce the loss of information in reconstructed data, which may affect to the performance of EEG-based pattern recognition systems. In this paper, we investigate the impact of lossy compression techniques on the performance of EEG-based pattern recognition systems including seizure recognition and person recognition. Our experiments are conducted on two public databases using two different EEG lossy compression techniques. Experimental results show that the recognition performance is not significantly reduced when using lossy techniques at high compression ratios.
