Final Project Reports for 2019

There were two options for the course project. Students either chose their own topic ("Custom Project"), or took part in a competition to build Question Answering models for the SQuAD 2.0 challenge ("Default Project").

You can find links to previous years' reports under Previous Offerings on the homepage.
