[ allennlp.modules.matrix_attention.matrix_attention ]
class MatrixAttention(torch.nn.Module, Registrable)
MatrixAttention takes two matrices as input and returns a matrix of attentions.
We compute the similarity between each row in each matrix and return unnormalized similarity scores. Because these scores are unnormalized, we don't take a mask as input; it's up to the caller to deal with masking properly when this output is used.
