Theory for understanding models

[Desperado17]

Greetings,

I'm studying neural networks and I'm currently browsing through PINTO model zoo to understand the traffic component detection. Can you give me a document that will explain what each step in such a model does? Like in yolopv2_post_192x320 for example?
