ToFFi -- Toolbox for Frequency-based Fingerprinting of Brain Signals
Michał K. Komorowski, Krzysztof Rykaczewski, Tomasz Piotrowski +5
Spectral fingerprints (SFs) are unique power spectra signatures of human brain regions of interest (ROIs, Keitel & Gross, 2016). SFs allow for accurate ROI identification and can s…
Relaxed Zero-Forcing Beamformer under Temporally-Correlated Interference
Takehiro Kono, Masahiro Yukawa, Tomasz Piotrowski
The relaxed zero-forcing (RZF) beamformer is a quadratically-and-linearly constrained minimum variance beamformer. The central question addressed in this paper is whether RZF perfo…
Iterative Neural Networks with Bounded Weights
Tomasz Piotrowski, Krzysztof Rykaczewski
A recent analysis of a model of iterative neural network in Hilbert spaces established fundamental properties of such networks, such as existence of the fixed points sets, converge…
supFunSim: : spatial filtering toolbox for EEG
Krzysztof Rykaczewski, Jan Nikadon, Włodzisław Duch +1
Recognition and interpretation of brain activity patterns from EEG or MEG signals is one of the most important tasks in cognitive neuroscience, requiring sophisticated methods of s…
