Exercise 8 - nn_model .
Is there a reference , or class notes slide# to understand nn_model better?

→ Would below be the correct way to initialize parameter?
It is throwing an error (NameError: name ‘W1’ is not defined).

# Initialize parameters
#(≈ 1 line of code)
# parameters = ...
# YOUR CODE STARTS HERE
parameters = {"W1": W1,
              "b1": b1,
              "W2": W2,
              "b2": b2}

Sincerely,
A

In this case, you just need to use one of the functions you already completed earlier in the exercise (initialize_parameters).

No, it is not. See @hackyon’s reply.
