Deep learning QC

Challenge

We lack fibr ratings for 483 subjects in this release.
We don't want to rely on our army of swipers for future releases.

Solution

Train a deep learning model to predict QC scores from the imaging alone

Convolutional neural network architecture (part 1)

Convolutional neural network architecture (part 2)

Deep learning loss curves

Loss stabilizes after ~20 epochs, for both and imaging only model and a model with imaging and QC metric input.
