Hi, thank you for your paper and code.
I read the paper and try to understand the model in train_val.prototxt
.
As far as i know, final1
& final2
are both ranking functions, and labelr
produces labels of {-1, 1}, then the ranking_loss is EuclideanLoss((final1 - final2) * labelr, 0)
my question is:
EuclideanLoss((final1 - final2) * labelr, 0)
is quite strange, because labelr
seems to be useless in this loss function.EuclideanLoss((final1 - final2) * labelr, 0)
is quite different from the loss function in paper, which i think is like [ max(0, (final1 - final2) * labelr) ]^2
.Did i miss something important?
Looking forward to your reply. Thanks again.
