bge-base-financial-matryoshka

BGE base Financial Matryoshka

This is a sentence-transformers model finetuned from BAAI/bge-base-en-v1.5 on the json dataset. 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("wu-tz/bge-base-financial-matryoshka")
# Run inference
sentences = [
    'We paid dividends on common shares and preferred shares of $8,136 in 2023, compared with $9,859 in 2022.',
    'How much were the dividends on common shares and preferred shares paid by AT&T Inc. in 2023?',
    'What was the gross unrecognized tax benefit at the beginning of the year 2021?',
]
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]

  <code>Depreciation and amortization totaled $4,856 as recorded in the financial statements.</code>	<code>How much did depreciation and amortization total to in the financial statements?</code>
  <code>On a segment basis, we expect: •Ford Pro EBIT of $8 billion to $9 billion driven by continued growth and favorable mix, partially offset by moderated pricing •Ford Blue EBIT of $7 billion to $7.5 billion, reflecting a balanced market equation, including the impact of our all-new F-150 launch; we also expect costs to be flat as we offset higher labor and product cost with efficiencies</code>	<code>What are the anticipated 2024 EBIT contributions for the Ford Pro and Ford Blue segments?</code>
