BERT is a method of pretraining language representations that was used to create models that NLP practicioners can then download and use for free. What is BERT?īERT (Bidirectional Encoder Representations from Transformers), released in late 2018, is the model we will use in this tutorial to provide readers with a better understanding of and practical guidance for using transfer learning models in NLP. Unfortunately, for many starting out in NLP and even for some experienced practicioners, the theory and practical application of these powerful models is still not well understood.

Transfer learning, particularly models like Allen AI’s ELMO, OpenAI’s Open-GPT, and Google’s BERT allowed researchers to smash multiple benchmarks with minimal task-specific fine-tuning and provided the rest of the NLP community with pretrained models that could easily (with less data and less compute time) be fine-tuned and implemented to produce state of the art results. Optimizer & Learning Rate SchedulerĢ018 was a breakthrough year in NLP. I’ve also published a video walkthrough of this post on my YouTube channel! Contents

The Colab Notebook will allow you to run the code and inspect it as you read through.

The blog post includes a comments section for discussion.

This post is presented in two forms–as a blog post here and as a Colab Notebook here.

More broadly, I describe the practical application of transfer learning in NLP to create high performance models with minimal effort on a range of NLP tasks. In this tutorial I’ll show you how to use BERT with the huggingface PyTorch library to quickly and efficiently fine-tune a model to get near state of the art performance in sentence classification. See Revision History at the end for details. Revised on 3/20/20 - Switched to tokenizer.encode_plus and added validation loss.
