Classification For NLP classification the current state of the art approach is Universal Language Model Fine-tuning (ULMFiT). It alleviates the previously used unidirectionality constraint by using a newer "masked language model" (MLM) that randomly masks some of the words from the sentence and predicts the original vocabulary of words based only on its context. Fine-tuning using BERT BERT addresses the previously mentioned unidirectional constraints by proposing a new pre-training objective: the “masked language model”(MLM). * 9 pages, short paper at ACL 2019. BERT Fine-Tuning Tutorial with PyTorch. , the output of the Transformer) for the first token in the input, which by construction corresponds to the the special [CLS] word embedding. All fine tuning and BERT experiments were done on the CLS token. Our contributions include: (1) a new state-of-the-art. BERT chooses a task-specific fine-tuning learning rate which performs the best on the development set Observations MLM does converge marginally slower than a left-to-right model (which predicts every token), but the empirical improvements of the MLM model far outweigh the increased training cost. In feature extraction demo, you should be able to get the same extraction results as the official model chinese_L-12_H-768_A-12.

Fine-tuning using BERT BERT addresses the previously mentioned unidirectional constraints by proposing a new pre-training objective: the “masked language model”(MLM). I want to fine-tune BERT for Q & A in a different way than the SQuAD mission: I have pairs of (question, answer) Part of them are the correct answer (Label - 1) Part of them are the incorrect answer (Label - 0) I want to fine-tune BERT to learn the classification mission: Given a pair of (q, a), predict if a is a correct answer for q. We'll use WandB's hyperparameter Sweeps later on. Recent advances in language representation using neural networks have made it viable to transfer the learned internal states of a trained model to downstream natural language processing tasks, such as named entity. Challenges As we have lots of training data it becomes quite difficult to train even with a GPU, so we used Google's TPU for fine-tuning task. However, if the BERT model is only pretrained and not fine-tuned on any downstream task, embeddings on those two symbols are meaningless. By fine-tuning BERT, we are now able to get away with training a model to good performance on a much smaller amount of training data. separating questions/ answers).
