Proximal Policy Optimization - Week 11

This week, I finally completed the backward process of the network. The problem is a little bit of challenge for me in the beginning. The key to solving this problem is that we need to have a clear understanding of how to network graph build so that we can backward the error through the graph. If I come across the same problem with more complicated graph, I think I can solve it on my own. I am here to thank that give me much help in practice.

Thanks for reading :).
