dtunkelang/bag-of-documents-minilm-6m-mnrl

The 6M-MNRL bag-of-documents retriever: all-MiniLM-L6-v2 fine-tuned with MultipleNegativesRankingLoss on ~1.9M bag-derived (query, document) pairs from the Amazon ESCI catalog. Part of the bag-of-documents retrieval research; see the live demo.

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("sentence_transformers_model_id")
# Run inference
sentences = [
    'pet products for dogs',
    'PetzPaw Pet Products All Natural Dog Treats Healthy Treats for Your Pet Made in the USA. No Grain, Wheat, Soy, Gluten. Great Tasting Beef Snacks for Any Breed - Perfect for Dog Training',
    'Acacia Salad Tongs - 12" Wooden Salad Servers Wood Salad Serving Utensils - Wood Salad Spoon & Fork Set.',
]
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,  0.6096, -0.0091],
#         [ 0.6096,  1.0000,  0.0292],
#         [-0.0091,  0.0292,  1.0000]])
