Hi everybody,
I’m working with Seq2seq networks for NLP purposes and almost new to this Deep Learning area. Just have a question about matrix multiplication on Pytorch.
Suppose that I have these vectors:
a = shape(2, 34, 200)
b = shape (2,6, 200)

mask = shape(2,34)

mask is a 0-1 vector denoting specific tokens in a vector. (1: exists, 0: otherwise)
Here is the work I wanna do: I want to use mask vector to find the associated rows (denoted by 1 in mask) and multiply these rows by ‘b’ vector. As for this discussion, b vector associates with those rows in the a vector that has value 1 in the mask.
