This is a sentence-transformers model finetuned from intfloat/multilingual-e5-large-instruct. It maps sentences & paragraphs to a 1024-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:

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("Data-Lab/multilingual-e5-large-instruct-embedder-tg")
# Run inference
sentences = [
    'паста томатная',
    'Instruct: Найти похожие продукты на основе деталей\nQuery: Паста томатная, 250 г томатная паста, кулинария, свежие ингредиенты, насыщенный вкус, универсальное применение, консистенция',
    'Instruct: Найти похожие продукты на основе деталей\nQuery: Соус Filippo Berio томатный Арраббьята 340 г соус, итальянская кухня, без консервантов, для пасты, острый, натуральные ингредиенты, высокое качество, томатный соус, органические продукты',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 1024]

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