Hello,
yes, it is a classification problem. I have 88 possible musical notes. And each target represents an isolate note.
My loss fuction is Binary Cross Entropy Loss, nn.BCELoss(). This is because the target is like:
[0,0,0,0,1,0,0,0, …,0]. The possition with 1 represents the note, so, in this case, the note is the number 4.
