I have read the lstmcell code in mxnet. However, I have a question.
The following code is the part of lstmcell:
next_c = symbol._internal._plus(forget_gate * states, in_gate * in_transform,
next_h = symbol._internal._mul(out_gate, symbol.Activation(next_c, act_type=“tanh”),
I want to know the detail of “symbol._internal._plus” and the difference between it and “mxnet.symbol.broadcast_plus”, but I don’t find it in the mxnet document.
Could any one explain it for me? Thanks so much!!
