from the mentors feedback:

  • I think there is an error in lesson6_0 :
    • it says a_0' = W^00_1x_0 + W^01_1x_1 ... + b_0 + b_1 ...
    • I think it should just be a_0' = W^00_1x_0 + W^01_1x_1 ... + b_0
    • without adding all the other biases
      • indeed, one bias for each activiation!
    • In the corresponding sketch, I think the second weight should also be labeled W_1^{10} rather than W_1^{01} in order to match the the equations (and the notion of the W*x dot product)
