# SentenceTransformer based on somosnlp-hackathon-2022/paraphrase-spanish-distilroberta

This is a [sentence-transformers](https://www.SBERT.net) model finetuned from [somosnlp-hackathon-2022/paraphrase-spanish-distilroberta](https://huggingface.co/somosnlp-hackathon-2022/paraphrase-spanish-distilroberta). It maps sentences & paragraphs to a 768-dimensional dense vector space and can be used for semantic textual similarity, semantic search, paraphrase mining, text classification, clustering, and more.

## Model Details

### Model Description

- **Maximum Sequence Length:** 256 tokens
- **Output Dimensionality:** 768 tokens
- **Similarity Function:** Cosine Similarity
<!-- - **Training Dataset:** Unknown -->
<!-- - **Language:** Unknown -->
<!-- - **License:** Unknown -->

### Full Model Architecture

```
SentenceTransformer(
  (0): Transformer({'max_seq_length': 256, 'do_lower_case': False}) with Transformer model: RobertaModel 
  (1): Pooling({'word_embedding_dimension': 768, 'pooling_mode_cls_token': False, 'pooling_mode_mean_tokens': True, 'pooling_mode_max_tokens': False, 'pooling_mode_mean_sqrt_len_tokens': False, 'pooling_mode_weightedmean_tokens': False, 'pooling_mode_lasttoken': False, 'include_prompt': True})
)
```

## Usage

### Direct Usage (Sentence Transformers)

First install the Sentence Transformers library:

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

Then you can load this model and run inference.
```python
from sentence_transformers import SentenceTransformer

# Download from the 🤗 Hub
model = SentenceTransformer("dfsandovalp01/paraphrase-spanish-distilroberta-MDD-pucCO-V2")
# Run inference
sentences = [
    'Alimentos, Bebidas y Tabaco  Vegetales orgánicos secos',
    'Coliflo rdok elgon orgánica seca Coliflores  orgánicas secas',
    'Arame  orgánica seca Vegetales marinos orgánicos secos',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 768]

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities.shape)
# [3, 3]
```
