Minimal working example or tutorial showing how to use Pytorch's nn.TransformerDecoder for batch text generation in training and inference modes?
After a Googling around, I think this tutorial may suit your needs.
However, it seems you have a misconception about the Transformer decoder: in training mode there is no iteration at all. While LSTM-...

Bert for QuestionAnswering input exceeds 512
The maximum input length is a limitation of the model by construction. That number defines the length of the positional embedding table, so you cannot provide a longer input, because it is not ...

How to improve language model ex: BERT on unseen text in training?
It appears that your model is failing to generalize.
One option is to increase the amount and quality of the training data.
Other options include large-scale language model specific regularization ...

How does T5 model work on input and target data while transfer learning?
T5 is in fact a sequence-to-sequence model, it has an encoder that generates some hidden states representing the input and a decoder that generates the output. When you fine-tune the model you can ...

How to measure the accuracy of an NLP paraphrasing model?
Evaluation should always be specific to the target task and preferably rely on some unseen test set.
The target task is paraphrasing, so the evaluation should be designed to check externally how good ...

Possible NLP approaches to extract 'goals' from text
Well, A quick approach to this is using named entity recognition and POS tagging to identify key phrases in the text that are likely to be goals.
For example, you might look for phrases that contain ...

What Preprocessing is Needed for Semantic Search Using Pre-trained Hugging Face Transformers?
Resumes are quite different from classic text because there are many proper nouns (names, companies, places, etc.) and other data difficult to classify (phone numbers, marks, age, etc.).
That's why ...

BERT - How Question answering is different than classification
For Question Answering, you need 2 logits : one for the start position, one for the end position. Based on these 2 logits, you have an answer span (denoted by the start/end position).
In the source ...

Dynamic batching and padding batches for NLP in deep learning libraries
Great questions!
When training a model with batches of data with padded inputs, the padded tokens will take up GPU memory. This is because the padding zeros are still being stored in memory, even if ...
