Scripts to decompose EEG signals from the Bonn University [[1]](https://journals.aps.org/pre/abstract/10.1103/PhysRevE.64.061907) and NSC-ND [[2]](https://doi.org/10.1016/j.eswa.2011.09.093) datasets, according to five methods: Empirical Mode Decomposition (EMD) and its extensions (EEMD, CEEMDAN), Empirical Wavelet Transform (EWT) and Variational Mode Decomposition. 

Two datasets:
1. [University of Bonn EEG seizure dataset](http://epileptologie-bonn.de/cms/front_content.php?idcat=193&lang=3&changelang=3)
2. [Neurology & Sleep Centre, Hauz Khas, New Delhi dataset](https://www.researchgate.net/publication/308719109_EEG_Epilepsy_Datasets)  
Download EEG data to (1) BonnDataset/data/ and (2) NSC_ND/data/

"main_feats.py" opens and decomposes each EEG into N modes with [EMD](https://doi.org/10.1098/rspa.1998.0193), [EEMD](https://doi.org/10.1142/S1793536909000047), [CEEMDAN](https://doi.org/10.1016/j.bspc.2014.06.009), [VMD](https://doi.org/10.1109/TSP.2013.2288675) and [EWT](https://doi.org/10.1109/TSP.2013.2265222). Features from each mode are then extracted and written in .csv files.  

"main_classify.py" opens .csv files with features generated by "main_feats.py". Samples are split into training/testing sets into 5-folds for cross-validation. Several classifiers are evaluated and mean performance results are presented for 10 iterations.

"main_figs.py" plots figures that appear on the manuscript
The following packages are required: numpy, scipy, scikit-learn, pandas, matplotlib, [pyEMD](https://pypi.org/project/EMD-signal/), [ewtpy](https://pypi.org/project/ewtpy/), [vmdpy](https://pypi.org/project/vmdpy/), seaborn.
