dtunkelang/bag-of-documents-minilm-esci-supervised

A supervised baseline: all-MiniLM-L6-v2 fine-tuned with MultipleNegativesRankingLoss on ESCI relevance labels (not bag-derived), used as a comparison point for the bag-of-documents retrieval research.

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 = [
    'preservatives free eye drops',
    'Refresh Plus Lubricant Eye Drops, Preservative-Free, 0.01 Fl Oz Single-Use Containers, 30 Count (Pack of 1)',
    'Ocusoft Retaine MGD Ophthalmic Emulsion, Milky White Solution, 30 count Single Use Containers, 0.01 Fluid Ounce',
]
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, 0.7632, 0.4848],
#         [0.7632, 1.0000, 0.4949],
#         [0.4848, 0.4949, 1.0000]])
