SentenceTransformer based on llm-semantic-router/mmbert-embed-32k-2d-matryoshka

This is a sentence-transformers model finetuned from llm-semantic-router/mmbert-embed-32k-2d-matryoshka. 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("sentence_transformers_model_id")
# Run inference
sentences = [
    'What is included in Item 8 of the document?',
    'What is included in Item 8 of the document?\n\nAnswer: Financial Statements and Supplementary Data',
    'What is the content of Item 8 in the document?\n\nAnswer: Item 8 of the document includes Financial Statements and Supplementary Data.',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 768]

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities)
# tensor([[1.0078, 0.9297, 0.5508],
#         [0.9297, 0.9922, 0.6680],
#         [0.5508, 0.6680, 1.0000]], dtype=torch.bfloat16)

  What led to the increase in operating income margin for the Dollar Tree segment in 2022?	What led to the increase in operating income margin for the Dollar Tree segment in 2022? Answer: The increase in operating income margin for the Dollar Tree segment in 2022 was primarily due to the gross profit margin increase and a decrease in the selling, general and administrative expense rate.	What was the increase in the gross profit margin for the fiscal year 2022 compared to the previous year? Answer: The increase in the gross profit margin for the fiscal year 2022 compared to the previous year was 2.1%.
