Im2Latex help • /r/MachineLearning

Hi everyone, I was inspired by OpenAI's "Requests for Research" project list that was released a few days ago. In particular, I'm trying to tackle Project #2 on their list, Im2Latex. Unfortunately I'm a newbie when it comes to Machine Learning, and I've only completed one online book so far. I'm asking for some tutorials or online resources that could help me learn about some of the following: sequence to sequence models, attention, and in-depth OCR among other things. If you know of any such tutorials please post them here to help steer me in the right direction.
