# What is this?
|
||
|
|
|
||
|
|
A GPT-2 model (medium version, ~354.8 M parameters) for Danish text generation. The model was not pre-trained from scratch but adapted from the English version using [CLP-Transfer](https://arxiv.org/abs/2301.09626).
|
||
|
|
|
||
|
|
# How to use
|
||
|
|
|
||
|
|
Test the model using the pipeline from the [🤗 Transformers](https://github.com/huggingface/transformers) library:
|
||
|
|
|
||
|
|
```python
|
||
|
|
from transformers import pipeline
|
||
|
|
|
||
|
|
generator = pipeline("text-generation", model = "KennethTM/gpt2-medium-danish")
|
||
|
|
text = generator("Manden arbejdede som")
|
||
|
|
|
||
|
|
print(text[0]["generated_text"])
|
||
|
|
```
|
||
|
|
|
||
|
|
Or load it using the Auto* classes:
|
||
|
|
|
||
|
|
```python
|
||
|
|
from transformers import AutoTokenizer, AutoModelForCausalLM
|
||
|
|
|
||
|
|
tokenizer = AutoTokenizer.from_pretrained("KennethTM/gpt2-medium-danish")
|
||
|
|
model = AutoModelForCausalLM.from_pretrained("KennethTM/gpt2-medium-danish")
|
||
|
|
```
|
||
|
|
|
||
|
|
# Model training
|
||
|
|
|
||
|
|
The training data are the Danish part of the [oscar dataset](https://huggingface.co/datasets/oscar) ('unshuffled_deduplicated_da') and a context length of 1024 tokens.
|
||
|
|
|
||
|
|
The model weights are initialized from the English [GPT-2 medium model](https://huggingface.co/gpt2-medium) ('source model') with new word token embeddings created from the Danish [GPT-2 small model](https://huggingface.co/KennethTM/gpt2-small-danish) ('helper model') using the [CLP-Transfer method](https://github.com/malteos/clp-transfer).
|
||
|
|
|
||
|
|
The model is trained using ~1.000.000 samples.
|
||
|
|
|
||
|
|
For reference, the model achieves a perplexity of 24.7 on 5.000 random validation samples.
|
||
|
|
|
||
|
|
The model is trained on an 8 GB GPU.

||

# Notes
|
||
|
|
|
||
|
|
This is a pre-trained model, for optimal performance it should be finetuned for new tasks.
