1.Introduction: In my previous blogs Text classification with pytorch and fastai part-1 and part-2, I explained how to prepare a text corpus to numerical vector format for neural network training with spacy, why should we use transfer learning for text data and how language model can be used as pre-trained model for transfer learning, here I will be discussing neural network classifier ...
The BucketIterator sorts the data to make batches with examples of similar length to avoid having too much padding. For that it needs to know what the sorting criterion is, which should be the text length. Since it is not fixed to a specific data layout, you can freely choose which field it should use, but that also means you must provide that information to sort_key.
