Abstract Among the most fascinating applications of Machine Learning are Neuroimaging and
Brain Machine Interfaces, which use the traces of the subject mental activity to respectively
build a model of the brain functional structure, or convert the subject’s brainwave functional
data into the command law of a mechatronic device.

Among the main ML challenges faced by both above domains is the variability of the
brainwave data, among different subjects and among different sessions for a given subject.
Assuming that single subject brainwave data do involve recurrent information patterns, the PhD
aims at building a subject-dependent code exploiting the brainwave functional data regularities.

A non-linear coding approach, based on neural nets (auto-encoders and deep neural nets), will apply to brainwave data the feature design mechanisms at the root of deep learning. The question is
to enforce the interpretability of the non-linear code in order to enable its qualitative evaluation.
