Code implementation of Backward propagation of L_ layers deep neural ntes is very ambiguous !؟
Is there any way to understand it well !?

Hello @muhmoud_shehata! I hope you are doing well.

We are here to help you. Could you be more specific which back propagation is unclear to you?
If you understand the forward propagation, you will be able to understand the back propagation too. There is a minor (but important) difference.

Best,
Saif.
