I have a strong mathematical and computer background (also with machine learning) and would like to switch to bioinformatics. I know a fair amount of biology. But I find it hard to find real world practical training in this field. So I would like to try to replicate some bioinformatics papers (with their provided data). Good beginner papers for me would be shorter ones where the biological problem is well stated and the problem is also fitted in to the bigger scope (or is just easily understandable). Do you have any papers to recommend?
