Blind Source Separation for Signal Processing Applications
Blind Source Separation (BSS) is a statistical approach to separating individual signals from an observed mixture of a group of signals. BSS relies on only very weak assumptions on the signals and the mixing process (hence the “blind” descriptor) and this blindness enables the technique to be used in a wide variety of situations. Research in the field of Blind Source Separation has resulted in ...
متن کاملFeature Selection and Blind Source Separation in an EEG-Based Brain-Computer Interface
Efforts to develop a brain-computer interface based on the scalp-recorded electroencephalogram (EEG) have progressed substantially over the past decade. However, most EEG-based BCI systems require subjects to perform tasks that do not directly map to simple binary commands such as “yes” or ”no”. Furthermore, successful BCI implementations often require extensive biofeedback training over many w...
متن کاملEEG Signal Processing for Epilepsy
At the presentmoment, threemethods can record functional and physiological changes within the brain with high temporal resolution of neuronal interactions at the network level: the electroencephalogram (EEG), the magnetoencephalogram (MEG), and functional magnetic resonance imaging (fMRI); each of these has advantages and shortcomings. MEG is not practical for experimental work when subjects ma...
متن کاملReview of Sparse Representation-Based Classification Methods on EEG Signal Processing for Epilepsy Detection, Brain-Computer Interface and Cognitive Impairment
At present, the sparse representation-based classification (SRC) has become an important approach in electroencephalograph (EEG) signal analysis, by which the data is sparsely represented on the basis of a fixed dictionary or learned dictionary and classified based on the reconstruction criteria. SRC methods have been used to analyze the EEG signals of epilepsy, cognitive impairment and brain c...
متن کاملBlind Source Separation Based of Brain Computer Interface System: A review
This study reviews the originality and development of the Brain Computer Interface (BCI) system and focus on the BCI system design based on Blind Source Separation (BSS) techniques. The study also provides the recent trends and discusses some of a new ideas for BSS techniques in BCI architecture, articles which discussing the BCI system development were analysed, types of the BCI systems and th...
