| | # roberta-base for QA |
| |
|
| | This is the [roberta-base](https://huggingface.co/roberta-base) model, fine-tuned using the [SQuAD2.0](https://huggingface.co/datasets/squad_v2) dataset. It's been trained on question-answer pairs, including unanswerable questions, for the task of Question Answering. |
| |
|
| |
|
| | ## Overview |
| | **Language model:** roberta-base |
| | **Language:** English |
| | **Downstream-task:** Extractive QA |
| | **Training data:** SQuAD 2.0 |
| | **Eval data:** SQuAD 2.0 |
| | **Code:** See [an example QA pipeline on Haystack](https://haystack.deepset.ai/tutorials/first-qa-system) |
| | **Infrastructure**: 4x Tesla v100 |
| |
|
| | ## Hyperparameters |
| |
|
| | ``` |
| | batch_size = 96 |
| | n_epochs = 2 |
| | base_LM_model = "roberta-base" |
| | max_seq_len = 386 |
| | learning_rate = 3e-5 |
| | lr_schedule = LinearWarmup |
| | warmup_proportion = 0.2 |
| | doc_stride=128 |
| | max_query_length=64 |
| | ``` |
| |
|
| | ## Using a distilled model instead |
| | Please note that we have also released a distilled version of this model called [deepset/tinyroberta-squad2](https://huggingface.co/deepset/tinyroberta-squad2). The distilled model has a comparable prediction quality and runs at twice the speed of the base model. |
| |
|
| | ## Usage |
| |
|
| | ### In Haystack |
| | Haystack is an NLP framework by deepset. You can use this model in a Haystack pipeline to do question answering at scale (over many documents). To load the model in [Haystack](https://github.com/deepset-ai/haystack/): |
| | ```python |
| | reader = FARMReader(model_name_or_path="deepset/roberta-base-squad2") |
| | # or |
| | reader = TransformersReader(model_name_or_path="deepset/roberta-base-squad2",tokenizer="deepset/roberta-base-squad2") |
| | ``` |
| | For a complete example of ``roberta-base-squad2`` being used for Question Answering, check out the [Tutorials in Haystack Documentation](https://haystack.deepset.ai/tutorials/first-qa-system) |
| |
|
| | ### In Transformers |
| | ```python |
| | from transformers import AutoModelForQuestionAnswering, AutoTokenizer, pipeline |
| | |
| | model_name = "deepset/roberta-base-squad2" |
| | |
| | # a) Get predictions |
| | nlp = pipeline('question-answering', model=model_name, tokenizer=model_name) |
| | QA_input = { |
| | 'question': 'Why is model conversion important?', |
| | 'context': 'The option to convert models between FARM and transformers gives freedom to the user and let people easily switch between frameworks.' |
| | } |
| | res = nlp(QA_input) |
| | |
| | # b) Load model & tokenizer |
| | model = AutoModelForQuestionAnswering.from_pretrained(model_name) |
| | tokenizer = AutoTokenizer.from_pretrained(model_name) |
| | ``` |
| |
|
| | ## Performance |
| | Evaluated on the SQuAD 2.0 dev set with the [official eval script](https://worksheets.codalab.org/rest/bundles/0x6b567e1cf2e041ec80d7098f031c5c9e/contents/blob/). |
