are you BiRnnJoin right ?

[Duum]

I find a interesting place , in your implement of BLSTM ,:

    local fwdProj = nn.Linear(nIn, nOut)(fwdX)
    local bwdProj = nn.Linear(nIn, nOut)(bwdX)

    local output = nn.CAddTable()({fwdProj, bwdProj})

I see you add two Linear unit of fwax and bwdX,But in the other implement , they are concatenate and fully connect to output layer. is there somthing wrong ? thank you
