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:

>>> from transformers import pipeline
>>> unmasker = pipeline('fill-mask', model='AI-Sweden-Models/roberta-large-1160k')
>>> unmasker("Huvudstaden i Sverige är <mask>.")

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)

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.
