[Torch5-devel] Concat in nn package

[Ronan C. <ro...@co...>]

Hey

   Jason pointed me out that Concat in nn package was not working. In 
fact, it was really buggy -- the implementation was not even finished. I 
corrected it, and improved it.

l = nn.Concat([dim]) takes now an optional dim argument: the dimension 
along which you want to concatenate (default 1) [that is new, before it 
was 1 with no option].

each modules added in Concat (with l:add(...)) must take the same number 
of inputs. their outputs are concatenated (along dim given in the 
constructor) and returned by the Concat layer.

you can feed tensors of any dimension to Concat (provided that the 
modules inside understand them). the outputed dimensions of each module 
might be different for the dimension "dim" but must (of course!) be the 
same in other dimensions.
