Datasets and Code

 

  1. Statistical spatial filter 'Fisher Criterion Beamformer' (FCB) (Toolbox: Python and Matlab code and application example) FCB is a statistical spatial filter that allows to increase the discrimination of 2-class event related potentials (ERP) recorded through electroencephalogram (EEG). The Matlab code provides the FCB toolbox and an example to test it on 2 different datasets: - dataset 1 : P300 oddball elicited in a communication speller (LSC speller) - dataset 2 : Error-related potentials (ErrP) elicited to detect and correct errors in LSC speller.  Python and Matlab Code available at: https://github.com/gpiresML/FCB-spatial-filter  . See paper Neuroscience Methods
  2. EOG image representation and CNN code: A 9-class dataset of Electrooculographic (EOG) signals represented by RGB images and code to train and evaluate a CNN model. Available at [dataset and CNN code: github]. Associated to paper IEEE Access  , J. Perdiz, L. Garrote, G. Pires and U. J. Nunes
  3. DynamicNet Python Class. DynamicNet is a Python class that automatically creates PyTorch Neural Networks (Convolutional-Neural-Network or a Feed-Forward-Neural-Network) only specifying in input a dictionary of parameters.
