Question about the Sign of SIMSE Loss

[MaxLiu245]

Hi, I was reading the DSN paper and saw you codes here. Nice codes!

But here I was wondering whether the loss codes in train.py's line 189 & 245 should be loss -= source_simse and loss -= target_simse. To confirm this, I read the original scale-invariant mean squared error paper, especially the eqn. 4 and made this conclusion.

I thought if so, the acc can be higher, and get close to DSN's result~

Hi, do you have the code of the original paper? It seems that the github link in the paper cannot be entered

The official implementation of the DSN model is in the archive brach, the link is as follows:

In addition to the sign, the log should also be used, according to the equation of SIMSE:

where
Is this right?
