# djovak/embedic-base

Say hello to **Embedić**, a group of new text embedding models finetuned for the Serbian language!

These models are particularly useful in Information Retrieval and RAG purposes. Check out images showcasing benchmark performance, you can beat previous SOTA with 5x fewer parameters!

Although specialized for Serbian(Cyrillic and Latin scripts), Embedić is Cross-lingual(it understands English too). So you can embed English docs, Serbian docs, or a combination of the two :)

This is a [sentence-transformers](https://www.SBERT.net) model: It maps sentences & paragraphs to a 768 dimensional dense vector space and can be used for tasks like clustering or semantic search.

<!--- Describe your model here -->

## 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 = ["ko je Nikola Tesla?", "Nikola Tesla je poznati pronalazač", "Nikola Jokić je poznati košarkaš"]

model = SentenceTransformer('djovak/embedic-base')
embeddings = model.encode(sentences)
print(embeddings)
```

### Important usage notes
- "ošišana latinica" (usage of c instead of ć, etc...) significantly deacreases search quality
- The usage of uppercase letters for named entities can significantly improve search quality

## Training

- Embedić models are fine-tuned from multilingual-e5 models and they come in 3 sizes (small, base, large).

- Training is done on a single 4070ti super GPU

- 3-step training: distillation, training on (query, text) pairs and finally fine-tuning with triplets.

### evaluation results

Evaluation on 3 tasks: Information Retrieval, Sentence Similarity, and Bitext mining. I personally translated the STS17 cross-lingual evaluation dataset and Spent 6,000$ on Google translate API, translating 4 IR evaluation datasets into Serbian language.

Evaluation datasets will be published as Part of [MTEB benchmark](https://huggingface.co./spaces/mteb/leaderboard) in the near future.
