Has been run several algorithms of code, such as YOLO (darknet), efficientdet (pytorch), centernet etc., but don't know the principle, also don't know the code, just some Ubuntu and python operation, so the code can run through,

Now facing the problem is how can I go to learn the theoretical knowledge, such as which began to look at the paper, from the problem of writing a paper now, don't know how to start,

Hope big elder guidance!!
