SentenceTransformer based on sentence-transformers/all-mpnet-base-v2

This is a sentence-transformers model finetuned from sentence-transformers/all-mpnet-base-v2. It maps sentences & paragraphs to a 768-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("alpcansoydas/product-model-17.10.24-ifhavemorethan100sampleperfamily")
# Run inference
sentences = [
    'SUN.Sun Fire T1000 Server, 6 core, 1.0GHz UltraSPARC T1 processor, 4GB DDR2 memory (4 * 1GB DIMMs), 160 SATA hard disk drive.',
    'Computer Equipment and Accessories',
    'Communications Devices and Accessories',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 768]

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