Possible error in Week3 lecture(decision boundary)


  • Link to the classroom item you are referring to:
  • Hi! I believe that there is an error on the decision boundaries lecture recordings. I think that the y=0 prediction would be inside the shape because that is when z<0, which is when we classify the prediction to be 0.

The figure is correct.
Do not assume that the weight values are positive.

Hello @Yasamin_Nouri,

Which shape? The upper or the lower?

Why is it z < 0? Can you show the math? :wink: You can be right.
