Very interesting and fun project! I was happy to help Abinav, although I think he didn't need too much help from my side.
One thing I liked about this project is that, even when machine learning tools are easily applied using the Wolfram Language, one can't escape from investigating sources, understanding them and creating a good training set.
This brings the students closer to what actual work is instead of just following a recipe or tutorial.
I also enjoyed Abinav's presentation. He has public speaking skills.
