31.12.2019 · You can use PackedSequence class as equivalent to keras masking. you can find more features at torch.nn.utils.rnn. Here putting example from packing for variable-length sequence inputs for rnn. import torch import torch.nn as nn from torch.autograd import Variable batch_size = 3 max_length = 3 hidden_size = 2 n_layers =1 # container batch_in = …
05.02.2017 · Hi all, I am recently trying to build a RNN model for some NLP task, during which I found that the RNN layer interface provided by pytorch (no matter what cell type, gru or lstm) doesn’t support masking the inputs. Masking is broadly used in NLP domain for the inputs within a single batch having different length (as inputs are generally bunch of natural language …
Masking attention weights in PyTorch. Dec 27, 2018 • Judit Ács. Attention has become ubiquitous in sequence learning tasks such as machine translation.

Mar 20, 2020 · The RNN module in PyTorch always returns 2 outputs. Total Output - Contains the hidden states associated with all elements (time-stamps) in the input sequence. Final Output - Contains the hidden ...
In LSTM, I don't have to worry about masking, but in transformer, since all the target is taken just at once, I really need to make sure the masking is ...
Dec 31, 2019 · Masking and computing loss for a padded batch sent through an RNN with a linear output layer in pytorch Hot Network Questions What is the lowest point below sealevel that we have built where a human can go?
31.12.2019 · Thanks for your answer. in this way, I need to have the start and end index of the non padded values, isn’t there any other more straightforward way like Masking layer in keras? one thing more, by slicing we feed the matrix with different shapes into RNN, is …
Mar 29, 2018 · pytorch-mask-rcnn. This is a Pytorch implementation of Mask R-CNN that is in large parts based on Matterport's Mask_RCNN. Matterport's repository is an implementation on Keras and TensorFlow. The following parts of the README are excerpts from the Matterport README.
11.12.2019 · Although a typical use case, I can't find one simple and clear guide on what is the canonical way to compute loss on a padded minibatch in pytorch, when sent through an RNN. I think a canonical pipeline could be: 1) The pytorch RNN expects a padded batch tensor of shape: (max_seq_len, batch_size, emb_size)

21.02.2017 · Performance-wise, running rnn on the whole input sequence, expanding mask and applying it to the whole rnn output will probably be better than having a loop over time. 3 Likes emanjavacas (Enrique Manjavacas) February 28, 2017, 12:37pm
