SentenceTransformer

This is a sentence-transformers model trained. 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 ๐Ÿค— Hub
model = SentenceTransformer("LamaDiab/MiniLM-V7-128BATCH-V6Data-SemanticEngine")
# Run inference
sentences = [
    'dive in finger delights',
    'ramadan desserts',
    'egyptian style chicken shawerma',
]
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, 0.4517, 0.3474],
#         [0.4517, 1.0000, 0.3222],
#         [0.3474, 0.3222, 1.0000]])
