# roberta-large-1160k

## Intended uses

You can use the raw model for masked language modeling, but it's mostly intended to be fine-tuned on a downstream task.

### How to use

You can use this model directly with a pipeline for masked language modeling:

```python
>>> from transformers import pipeline
>>> unmasker = pipeline('fill-mask', model='AI-Sweden-Models/roberta-large-1160k')
>>> unmasker("Huvudstaden i Sverige är <mask>.")
[{'score': 0.5841221213340759,
  'token': 1945,
  'token_str': ' Stockholm',
  'sequence': 'Huvudstaden i Sverige är Stockholm.'},
 {'score': 0.06775698810815811,
  'token': 5007,
  'token_str': ' Göteborg',
  'sequence': 'Huvudstaden i Sverige är Göteborg.'},
 {'score': 0.05057400465011597,
  'token': 5761,
  'token_str': ' Malmö',
  'sequence': 'Huvudstaden i Sverige är Malmö.'},
 {'score': 0.021936343982815742,
  'token': 21449,
  'token_str': ' Norrköping',
  'sequence': 'Huvudstaden i Sverige är Norrköping.'},
 {'score': 0.017798304557800293,
  'token': 5658,
  'token_str': ' Uppsala',
  'sequence': 'Huvudstaden i Sverige är Uppsala.'}]
```
```python
>>> unmasker("Hovedstaden i Norge er <mask>.")
[{'score': 0.6792309284210205,
  'token': 5158,
  'token_str': ' Oslo',
  'sequence': 'Hovedstaden i Norge er Oslo.'},
 {'score': 0.09379775077104568,
  'token': 15456,
  'token_str': ' Trondheim',
  'sequence': 'Hovedstaden i Norge er Trondheim.'},
 {'score': 0.052535850554704666,
  'token': 11370,
  'token_str': ' Bergen',
  'sequence': 'Hovedstaden i Norge er Bergen.'},
 {'score': 0.03465486690402031,
  'token': 29407,
  'token_str': ' hovedstaden',
  'sequence': 'Hovedstaden i Norge er hovedstaden.'},
 {'score': 0.03017985075712204,
  'token': 33311,
  'token_str': ' Kristiansand',
  'sequence': 'Hovedstaden i Norge er Kristiansand.'}]
```
```python
>>> unmasker("Danmarks hovedstad er <mask>.")
[{'score': 0.11624140292406082,
  'token': 4794,
  'token_str': ' København',
  'sequence': 'Danmarks hovedstad er København.'},
 {'score': 0.045051511377096176,
  'token': 7680,
  'token_str': ' død',
  'sequence': 'Danmarks hovedstad er død.'},
 {'score': 0.02936543896794319,
  'token': 10795,
  'token_str': ' lukket',
  'sequence': 'Danmarks hovedstad er lukket.'},
 {'score': 0.026030730456113815,
  'token': 13580,
  'token_str': ' Odense',
  'sequence': 'Danmarks hovedstad er Odense.'},
 {'score': 0.02130937948822975,
  'token': 16347,
  'token_str': ' Roskilde',
  'sequence': 'Danmarks hovedstad er Roskilde.'}]
```

Here is how to use this model to get the features of a given text in PyTorch:

```python
from transformers import RobertaTokenizer, RobertaModel
tokenizer = RobertaTokenizer.from_pretrained('AI-Sweden-Models/roberta-large-1160k')
model = RobertaModel.from_pretrained('AI-Sweden-Models/roberta-large-1160k')
text = "Replace me by any text you'd like."
encoded_input = tokenizer(text, return_tensors='pt')
output = model(**encoded_input)
```

## Training data
The Scandinavian subset of the Nordic Pile (Swedish, Norwegian, Danish), consisting of 414 962 688 text samples.

## Training procedure

The model was trained with the [optimum-habana](https://github.com/huggingface/optimum-habana) framework. Utilizing 8X Intel® Gaudi® 2 AI accelerators, managed by Intel Sweden AB.

The weights from https://huggingface.co./FacebookAI/roberta-large are used as initialization, and the tokenizer is trained from scratch.

This model is a checkpoint (1 160 000 / 1 350 790). The final run is 5 epochs. This is epoch: 4.29.

A batch size of 1536 was used.

## Evaluation results

When fine-tuned on downstream tasks, this model achieves the following results:
