The project is about applying CNNs to EEG data from CHB-MIT to predict seizure. It's a group project assigned at UNIVERSITA' DI CAMERINO for computer science bachelor. The objective of the project was to try to replicate the result obtained in the paper: Truong, Nhan Duy, et al. "Convolutional neural networks for seizure prediction using intracranial and scalp electroencephalogram." Neural Networks 105 (2018): 104-111.
The algorithm consist to create spectograms of the data and than use them with a CNN model to predict seizure.
More information are in presentazione.pdf and relazione.pdf. The two file are respectively the presentation and the relation of the work in italian language.
In the project anaconda was used to managed the packages. Packages required:
- keras 2.2.2
- python 3.6.6
- tensorflow 1.10.0
- matplotlib
- numpy
- pyedflib
- scipy
For the evaluation of the network, training and testing, the GPU is used to have a fast evaluation. By using the CPU the training time is a lot more slowly than using GPU. Packages required for GPU:
- tensorflow-GPU
For the using of the GPU this link was very useful to install all the driver for Ubuntu 18.04 LTS https://medium.com/@naomi.fridman/install-conda-tensorflow-gpu-and-keras-on-ubuntu-18-04-1b403e740e25 (Note that the GPU used was GTX 850M so I can't ensure that the guide linked will work for different hardware).
Download or clone the repository on your computer and set the parameters:
-
PARAMETERS_DATA_EDITING.txt: contain the parameters for the creation of the spectograms:
- pathDataSet: path of the folder containing the dataset;
- FirstPartPathOutput: path of the folder where spectograms will be saved;
-
PARAMETERS_CNN.txt: contain the parameters for the use of CNN:
- PathSpectogramFolder: Path of the folder containing the spectograms;
- OutputPath: file where to save the results;
- OutputPathModels: where to save the CNN models.
The dataset is downloadable from this site: https://archive.physionet.org/pn6/chbmit/. To get all the data it's suggested to use this command:
wget -r --no-parent https://archive.physionet.org/pn6/chbmit/
In the code only patients 1, 2, 5, 19, 21, 23 are used, the others are discarded for problems in the data. NOTE: For the patient 19 replace the summary file(chb19-summary.txt) with the one in this repository inside the folder summaryChanged.
After setted all the parameters run the code.
python DataserToSpectogram.py #Creation of the spectograms
python CNN.py #Creation of the CNN and evaluation of the model on the spectograms
python TestThreshold.py #Search the best thresold for each patient
