C1_W2_Lab1 Exercise 7. Why does normalization change the results so much?

Please try the following :

  1. Define a function get_sigmoid(pixel_value, weight) where you return the sigmoid for the pixel_value * weight value.
  2. Create a bunch of weights using np.linspace between 0 and 1e-5.
  3. See how sigmoid varies when pixel value is 255 and 1.

This should tell you which scale of values will help speed up learning keeping backpropagation in mind.
