Please, when you use Three Letter Abbreviations (TLAs) write out the TLA the first time you use it on a page. For example, you use the TLA CNN without ever defining it. What is CNN? When I Google it, I get the Cable News Network. Yes, I know that you meant a Convolutional Neural Network because of the context, and the RNN is a Recurrent Neural Network, but please, as a courtesy to the reader, write out the TLA the first time you use it. People like me, who have problems remember TLAs, will thank you!
