# cross-encoder-mmarco-german-distilbert-base

## Model description:
This model is a fine-tuned [cross-encoder](https://www.sbert.net/examples/training/cross-encoder/README.html) on the [MMARCO dataset](https://huggingface.co/datasets/unicamp-dl/mmarco) which is the machine translated version of the MS MARCO dataset.
As base model for the fine-tuning we use [distilbert-base-multilingual-cased](https://huggingface.co/distilbert-base-multilingual-cased)

Model input samples are tuples of the following format, either 
`<query, positive_paragraph>` assigned to 1 or `<query, negative_paragraph>` assigned to 0.
 
The model was trained for 1 epoch.

## Model usage
The cross-encoder model can be used like this:

```
from sentence_transformers import CrossEncoder
model = CrossEncoder('model_name')
scores = model.predict([('Query 1', 'Paragraph 1'), ('Query 2', 'Paragraph 2')])
```

The model will predict scores for the pairs `('Query 1', 'Paragraph 1')` and `('Query 2', 'Paragraph 2')`.

For more details on the usage of the cross-encoder models have a look into the [Sentence-Transformers](https://www.sbert.net/)

## Model Performance:
Model evaluation was done on 2000 evaluation paragraphs of the dataset.
