Question about CEloss formula #13

Open daheekwon opened 6 months ago

daheekwon commented 6 months ago

Hi, I'm now digesting PCL algorithm:)

I have a question on Eq.(6). The second term of denominator (Z) is Summation of exp(w_k z_j * alpha). But I'm not sure why the index of z here is "j" instead of "i".

Is it a typo z_j-> z_i? Or if not, what does this term imply?

Regards,
