How to add a L2 regularization term in my loss function

autograd
7

Sure, I know this is custom neural network.

I use the 3 layers CNN net defined by myself with the nn.MSELoss() before. It’s autograd.
But now I want to compare the results if loss function with or without L2 regularization term.

If I use autograd nn.MSELoss(), I can not make sure if there is a regular term included or not.
p.s.:I checked that parameter ‘weight_decay’ in optim means “add a L2 regular term” to loss function.:+1:

Furthermore, if I want to add a “L1” norm term in my loss function, I CANNOT USE THE autograd ?
