Attention_masks

WebAttention masks are tensors with the exact same shape as the input IDs tensor, filled with 0s and 1s: 1s indicate the corresponding tokens should be attended to, and 0s indicate the corresponding tokens should not be attended to (i.e., they should be ignored by the attention layers of the model). WebTL;DR In this tutorial, you’ll learn how to fine-tune BERT for sentiment analysis. You’ll do the required text preprocessing (special tokens, padding, and attention masks) and build a Sentiment Classifier using the amazing Transformers library by Hugging Face!
