SentenceTransformer based on sentence-transformers/all-MiniLM-L6-v2

This is a sentence-transformers model finetuned from sentence-transformers/all-MiniLM-L6-v2. 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:

pip install -U sentence-transformers

Then you can load this model and run inference.

from sentence_transformers import SentenceTransformer

# Download from the 🤗 Hub
model = SentenceTransformer("LamaDiab/v4MiniLM-V18Data-256ConstantBATCH-SemanticEngine")
# Run inference
sentences = [
    'italian dolce provolone',
    'experience the authentic taste of italy with our italian dolce provolone. indulge in its creamy texture, delicate flavors, and versatility in both simple and sophisticated culinary creations.',
    'trident - gum strawberry flavor - 5 per pack',
]
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, 0.8172, 0.1450],
#         [0.8172, 1.0000, 0.1964],
#         [0.1450, 0.1964, 1.0000]])
