in the first and second pytorch code, for function
I guess it should be
pytorch.nn.Module.apply(fn) Applies `fn` recursively to every submodule (as returned by
.children()) as well as self.
it doesn’t make sense to repeatedly initialize net and it’s aiming to initialize all parameters
Hi @kwang that’s a great catch. If we are to apply initialization to all the
Linear layers in the network, then we should replace
m inside the
Ps. While I was at it, I have fixed the naming of the functions too. The second function should be named
This is now fixed in master. You can soon see the changes in the next update to release branch.
For tied parameters (link), why is the gradient the sum of the gradients of the two layers? I was thinking it would be the product of the gradients of the two layers. Reasoning:
y = f(f(x))
dy/dx = f’(f(x))*f’(x) where x is a vector denoting the shared parameters.
