RIKEN ABSP Lab
The Cichocki Laboratory for
Brain Signal Processing (ABSP) investigates and develops tools and
software for analysis, extraction, enhancement, de-noising detection,
localization, recognition and classification of brain signals and
patterns, especially measured by high density array EEG/MEG and ERP/EMG
are interested in
intelligent biomedical signal processing and nonlinear system theory
approaches in computational neuroscience, with an emphasis on neural
network models with underlying components (processing units) and
biologically plausible learning algorithms.
the higher order functioning of the brain, it is necessary to develop
new methods of signal processing for brain data. On the other hand, the
brain itself performs excellent information processing, by using
diversified representations of information.
focuses on two aspects of the
brain signal processing, namely analysis and modeling. The first goal
is to develop advanced methods for brain multi-dimensional and
multi-modal data analysis, especially for EEG, MEG, EMG and
spatio-temporal pictorial signal from fMRI or optical recordings.
Our second goal is to elucidate brain signal processing through its
modeling and engineering applications. We analyze models of
biologically plausible neural networks with adaptive learning rules in
order to understand brain information processing in the visual,
auditory, olfactory and somatosensory systems. To this end, we
implement engineering designs of brain-style pattern recognition,
classification and cognitive systems.
Main Tasks and Applications
- Development of advanced methods for brain data analysis and
- Development of generalized component analysis (ICA, SCA,
NMF, SPCA) and blind source separation (BSS).
- Semi-blind extraction and analysis of ERP transient signals.
- Statistical analysis of multi-electrode signals- especially
analysis of brain signals from EEG/MEG recording.
- Developments of neural network models and their engineering
- Auditory signal processing and speech enhancement.
