 ## About the code
 -	The ```features/``` folder will contain the extracted features after running the feature extraction codes. These are not included in this repository to limit the storage.
--	The ```results/``` contains a subfolder for each experiment with the final predictions for devel and test subset (saved as csv file) + plot of the normalized confusion matrix saved as jpg image (only for predictions test subset)
