Here is how to use this model to get the features of a given text in PyTorch:
|
| 79 |
-
|
| 80 |
-
```python
|
| 81 |
-
from transformers import RobertaTokenizer, RobertaModel
|
| 82 |

-
model = RobertaModel.from_pretrained('roberta-large')

-
encoded_input = tokenizer(text, return_tensors='pt')

| 86 |
-
output = model(**encoded_input)
|
| 87 |
-
```
|
| 88 |
-
|
| 89 |
-
and in TensorFlow:
|
| 90 |
-
|
| 91 |

```python

### Limitations and bias
|

-
|
| 102 |
-
The training data used for this model contains a lot of unfiltered content from the internet, which is far from
|
| 103 |
-
neutral. Therefore, the model can have biased predictions:
|
| 104 |
-
|
| 105 |
-

|

|
| 107 |

## Training data
|
| 158 |
-
|
| 159 |
-
The RoBERTa model was pretrained on the reunion of five datasets:
|
| 160 |
-
- [BookCorpus](https://yknzhu.wixsite.com/mbweb), a dataset consisting of 11,038 unpublished books;
|
| 161 |
-
- [English Wikipedia](https://en.wikipedia.org/wiki/English_Wikipedia) (excluding lists, tables and headers) ;
|
| 162 |
-
- [CC-News](https://commoncrawl.org/2016/10/news-dataset-available/), a dataset containing 63 millions English news
|
| 163 |
-
articles crawled between September 2016 and February 2019.
|
| 164 |
-
- [OpenWebText](https://github.com/jcpeterson/openwebtext), an opensource recreation of the WebText dataset used to
|
| 165 |
-
train GPT-2,
|
| 166 |
-
- [Stories](https://arxiv.org/abs/1806.02847) a dataset containing a subset of CommonCrawl data filtered to match the
|
| 167 |
-
story-like style of Winograd schemas.
|
| 168 |
-
|
| 169 |
-
Together theses datasets weight 160GB of text.
|
| 170 |
-
|
| 171 |
-
## Training procedure
|
| 172 |
-
|
| 173 |
-
### Preprocessing
|
| 174 |
-
|
| 175 |
-
The texts are tokenized using a byte version of Byte-Pair Encoding (BPE) and a vocabulary size of 50,000. The inputs of
|
| 176 |
-
the model take pieces of 512 contiguous token that may span over documents. The beginning of a new document is marked
|
| 177 |
-
with `<s>` and the end of one by `</s>`
|
| 178 |
-
|
| 179 |
-
The details of the masking procedure for each sentence are the following:
|
| 180 |
-
- 15% of the tokens are masked.
|
| 181 |
-
- In 80% of the cases, the masked tokens are replaced by `<mask>`.
|
| 182 |
-
|
| 183 |
-
- In 10% of the cases, the masked tokens are replaced by a random token (different) from the one they replace.
|
| 184 |
-
- In the 10% remaining cases, the masked tokens are left as is.
|
| 185 |
-
|
| 186 |
-
Contrary to BERT, the masking is done dynamically during pretraining (e.g., it changes at each epoch and is not fixed).
|
| 187 |
-
|
| 188 |
-
### Pretraining
|
| 189 |
-
|
| 190 |
-
The model was trained on 1024 V100 GPUs for 500K steps with a batch size of 8K and a sequence length of 512. The
|
| 191 |
-
optimizer used is Adam with a learning rate of 4e-4, \\(\beta_{1} = 0.9\\), \\(\beta_{2} = 0.98\\) and
|
| 192 |
-
\\(\epsilon = 1e-6\\), a weight decay of 0.01, learning rate warmup for 30,000 steps and linear decay of the learning
|
| 193 |
-
rate after.

# MUPPET RoBERTa large model
|
| 12 |
|
| 13 |
+
This is a Massive Multi-task Pre-finetuned version of Roberta large. It was introduced in
|
| 14 |
+
[this paper](https://arxiv.org/abs/2101.11038). The model improves over roberta-base in a wide range of GLUE, QA tasks (details can be found in the paper). The gains in
|
| 15 |
+
smaller datasets are significant.
|
| 16 |
+
|
| 17 |
+
Note: This checkpoint does not contain the classificaiton/MRC heads used during pre-finetuning due to compatibility issues and hence you might get slightly lower performance than that reported in the paper on some datasets
