Biosignal Informatics and Processing
I am advocating this new concept of research area called biosignal informatics. This novel area aims at unifying various concepts concerning biomedical signal processing, machine learning, neuroscience, mathematical engineering, etc.
Graph signal processing for electroencephalogram (EEG) with application to brain-computer interfaces
Introducing a graph structure to electrode location and the use of graph Fourier transform lead to effective feature extraction from EEG.
