Hi, @yanx27 ,

Thanks a lot for releasing such useful package. When reading the code, I found a variable "smpws_pl" but cannot figure out its meaning. Would does the variable "smpws" mean? Does it mean remission value?

THX!

@amiltonwong Hi, 'smpws_pl' is used to record weight of each point, because we use weighted cross-entropy loss. It also masks point we don't need to calculate loss.
