It’s hard reading random papers like that without deeply understanding the problem they are trying to solve. Sometimes understanding the true problem is more difficult than the solution in the papers.
What I would suggest instead as a learning exercise is to pick a domain you want to tackle and reinvent the wheel by implementing it. while doing so you’ll naturally find yourself digging into research papers. The advantage here is that during implementation you’d have understood the problem and the context much better and can relate to what the authors are discussing and trying to solve. Instead of moving backwards from solution to problem.
