| # CSR Sparse Encoder |
|
|
| This is a [CSR Sparse Encoder](https://www.sbert.net/docs/sparse_encoder/usage/usage.html) model finetuned from [almanach/camembert-large](https://huggingface.co/almanach/camembert-large) on the [french_sts](https://huggingface.co/datasets/CATIE-AQ/frenchSTS) dataset using the [sentence-transformers](https://www.SBERT.net) library. It maps sentences & paragraphs to a 4096-dimensional sparse vector space with 256 maximum active dimensions and can be used for semantic search and sparse retrieval. |

| - **Maximum Sequence Length:** 512 tokens |
| - **Output Dimensionality:** 4096 dimensions (trained with 256 maximum active dimensions) |
| - **Similarity Function:** Cosine Similarity |
| - **Training Dataset:** |
| - [french_sts](https://huggingface.co/datasets/CATIE-AQ/frenchSTS) |

|
| ## 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 SparseEncoder |
| |
| # Download from the 🤗 Hub |
| model = SparseEncoder("bourdoiscatie/SPLADE_camembert-large_STS") |
| # Run inference |
| sentences = [ |
| "Oui, je peux vous dire d'après mon expérience personnelle qu'ils ont certainement sifflé.", |
| "Il est vrai que les bombes de la Seconde Guerre mondiale faisaient un bruit de sifflet lorsqu'elles tombaient.", |
| "J'envisage de dépenser les 48 dollars par mois pour le système GTD (Getting things done) annoncé par David Allen.", |
| ] |
| embeddings = model.encode(sentences) |
| print(embeddings.shape) |
| # [3, 4096] |
| |
| # Get the similarity scores for the embeddings |
| similarities = model.similarity(embeddings, embeddings) |
| print(similarities) |
| # tensor([[1.0000, 0.3673, 0.2794], |
| # [0.3673, 1.0000, 0.2023], |
| # [0.2794, 0.2023, 1.0000]]) |
