	# Lemone-embedded, pre-built embeddings dataset for French taxation.

	<div class="not-prose bg-gradient-to-r from-gray-50-to-white text-gray-900 border" style="border-radius: 8px; padding: 0.5rem 1rem;">
	<p>This database presents the embeddings generated by the Lemone-embed-pro model and aims at a large-scale distribution of the model even for the GPU-poor.</p>
	</div>

	This sentence transformers model, specifically designed for French taxation, has been fine-tuned on a dataset comprising 43 million tokens, integrating a blend of semi-synthetic and fully synthetic data generated by GPT-4 Turbo and Llama 3.1 70B, which have been further refined through evol-instruction tuning and manual curation.

	The model is tailored to meet the specific demands of information retrieval across large-scale tax-related corpora, supporting the implementation of production-ready Retrieval-Augmented Generation (RAG) applications. Its primary purpose is to enhance the efficiency and accuracy of legal processes in the taxation domain, with an emphasis on delivering consistent performance in real-world settings, while also contributing to advancements in legal natural language processing research.

	This is a sentence-transformers model finetuned from Alibaba-NLP/gte-multilingual-base. 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.

	## Usage with ChromaDB

	We recommend integration via a vector-store to produce an optimal RAG pipeline. Here's a code extract for producing such a database with ChromaDB:

	```python
	import chromadb
	import polars as pl

	from chromadb.config import Settings
	from chromadb.utils import embedding_functions
	from torch.cuda import is_available

	client = chromadb.PersistentClient(
	path="./chroma.db",
	settings=Settings(anonymized_telemetry=False)
	)

	sentence_transformer_ef = embedding_functions.SentenceTransformerEmbeddingFunction(
	model_name="louisbrulenaudet/lemone-embed-pro",
	device="cuda" if is_available() else "cpu",
	trust_remote_code=True
	)

	collection = client.get_or_create_collection(
	name="tax",
	embedding_function=sentence_transformer_ef
	)

	dataframe = pl.scan_parquet('hf://datasets/louisbrulenaudet/lemone-docs-embedded/data/train-00000-of-00001.parquet').filter(
	pl.col(
	"text"
	).is_not_null()
	).collect()

	collection.add(
	embeddings=dataframe["lemone_pro_embeddings"].to_list(),
	documents=dataframe["text"].to_list(),
	metadatas=dataframe.drop(
	[
	"lemone_pro_embeddings",
	"text"
	]
	).to_dicts(),
	ids=[
	str(i) for i in range(0, dataframe.shape[0])
	]
	)
	```
