Advanced Usage

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

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)

📚 Documentation

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 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:

As by (2024/03/26) it is ranked #2 at ScandEval after gpt - 4 - 0613.

🔧 Technical Details

The model uses the optimum - habana framework for training. It starts with the weights from https://huggingface.co/FacebookAI/roberta-large and trains the tokenizer from scratch. It is trained on 8X Intel® Gaudi® 2 AI accelerators managed by Intel Sweden AB.
