# SentenceTransformer based on ibm-granite/granite-embedding-small-english-r2

This is a [sentence-transformers](https://www.SBERT.net) model finetuned from [ibm-granite/granite-embedding-small-english-r2](https://huggingface.co/ibm-granite/granite-embedding-small-english-r2). It maps sentences & paragraphs to a 384-dimensional dense vector space and can be used for semantic textual similarity, semantic search, paraphrase mining, text classification, clustering, and more.

## 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("sentence_transformers_model_id")
# Run inference
sentences = [
    'PyTorch',
    'An open source machine learning framework',
    'The region of the atmosphere and outer space seen from the earth',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 384]

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities)
# tensor([[1.0000, 0.4991, 0.1094],
#         [0.4991, 1.0000, 0.4888],
#         [0.1094, 0.4888, 1.0000]])
```
