I have tried simple combination of classification loss
and mutual loss
, yet also in another project. I used two ResNet-50. The CMC Rank-1 accuray of baseline is ~84%; adding mutual loss
gains over 1 point improvement.
In this project, GL + IDL + ML + TWGD
has additional probability mutual loss
and global distance mutual loss
than baseline GL + IDL + TWGD
. I did not try adding only probability mutual loss
here.

hi
I'm having some troubles
-
in the paper, the classification loss is how to compute?
input a image (224x224) to resnet 50 , the output is 7x7x2048 feature , and then? I have no idea
is it using fully conv and softmax to calssification? -
how about mutual loss? Is it just combine two different loss
( for example, triplet loss + classification loss = mutual losshow about metric loss?
thanks you

You can look into the structure of ResNet-50. For input of size
224x224x3
, the output of ResNet-50 conv5 is7x7x2048
. Then there is a average pooling layer reducing it to1x1x2048
. Then there is the final FC layer. Besides, classification loss is calculated as in object recognition task. -
Mutual loss is not the sum of losses. You can refer to paper Deep Mutual Learning.
