# mteb-pt/average_fasttext_wiki.pt.align.300

This is an adaptation of pre-trained Portuguese fastText Word Embeddings to a [sentence-transformers](https://www.SBERT.net) model.  

The original pre-trained word embeddings can be found at: [https://fasttext.cc/docs/en/aligned-vectors.html](https://fasttext.cc/docs/en/aligned-vectors.html).  

This model maps sentences & paragraphs to a 300 dimensional dense vector space and can be used for tasks like clustering or semantic search.

## Usage (Sentence-Transformers)

Using this model becomes easy when you have [sentence-transformers](https://www.SBERT.net) installed:

```
pip install -U sentence-transformers
```

Then you can use the model like this:

```python
from sentence_transformers import SentenceTransformer
sentences = ["This is an example sentence", "Each sentence is converted"]

model = SentenceTransformer('mteb-pt/average_fasttext_wiki.pt.align.300')
embeddings = model.encode(sentences)
print(embeddings)
```

## Evaluation Results

For an automated evaluation of this model, see the *Portuguese MTEB Leaderboard*: [mteb-pt/leaderboard](https://huggingface.co/spaces/mteb-pt/leaderboard)
