Default clarification on lecture 9

I have a slight problem with delta_E_in in slide 23 of lecture 9.

I think there should be a negative sign in the exponentiation term,
e^(y_n * w.transpose * x_n) should be e^( - y_n * w.transpose * x_n )

as it would result from differentiating the cross entropy error? Please clarify.

Thank you
