how to skip some nodes ?

[Minwei Feng]

Hey guys,

suppose I create a gmodule with two input A and B.
Now A will be the training example, and B will be some random sampled negative example
Now during forward path I want the full calculation only be done once, and from the second time only B will be changing and A will be fixed, so the calculation related with A is not necessary to be conducted again.

So is there some example show that how to skip some nodes in the nngraph during forward pass?

Currently, the way to do is would be to have different graphs that share those modules and use them in different parts of your training.
