This part 3 assignment is about the backward propagation (e.g. feed backward). In this assignment, you are required to show the pencil and paper manual calculation (no Excel) on the following:
1) calculate the total error
2) calculate the gradients for output layer weights,
3) calculate the output layer bias weights,
4) gradients for hidden layer weights,
5) hidden layer bias weights,
6) updating the layer edge weights
7) updating the bias edge weights
8) Illustrate the final DL model with the updated weights in all.
