Default Re: Hw5 Q8 E_out

I am also a little unsure about exactly how this equation works:
E_{out} = \frac{1}{M} \sum_{i=1}^M \ln (1+e^{-Y_i w^\top X_i})

Obviously the more negative {-Y_i w^\top X_i} is the closer E_out is to zero which is good. So is w supposed to be normalized? I presume so because otherwise I could just scale w and then E_out becomes very small. And if it is normalized then the values I'm getting for E_in and E_out are both much greater than any of the options. (Maybe it's meant to be like that, if so it's quite unnerving.)
