Kaggle Competition Bristol-Myers Squibb – Molecular Translation

Hello!
Is anyone going to participate in this competition? I am looking to discuss it.
What are the “classical” approach to solve this kind of problem? Is this usual image2text task?
How can I encode some chemical rules of formula creation to make the shortcut in learning?

Not sure that I will have time to participate, but discussing the theory of solving this sound really fun.

From what I found on https://en.wikipedia.org/wiki/International_Chemical_Identifier the prediction is standard and have some rules. Is it an option to train classifier for one part of the formula and then encode translation to the InChI without deep learning?
