For the last few weeks, I’ve been taking part in a small weekly neural net study group run by Michael Nielsen. It’s been really awesome! Neural nets are very very cool! They’re so cool, I had to use them somehow. Having been interested in mathematical handwriting recognition for a long time, I decided to train a neural net to clean up images of blackboards as a short weekend project/break. Thanks to Dror Bar-Natan’s Academic Pensieve, it was easy to get a bunch of data.
