This is a sentence-transformers model finetuned from BAAI/bge-base-en-v1.5. 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.

python

from sentence_transformers import SentenceTransformer

# Download from the 🤗 Hub
model = SentenceTransformer("ppuva1/bge-base-financial-matryoshka-2")
# Run inference
sentences = [
    'The Company uses cash flow hedges to minimize the variability in cash flows of assets or liabilities or forecasted transactions caused by fluctuations in foreign currency exchange rates, commodity prices or interest. The changes in the fair values of derivatives designated as cash flow hedges are recorded in AOCI and are reclassified into the line item in our consolidated statement of income in which the hedged items are recorded in the same period the hedged items affect earnings.',
    'What financial instruments does the Company use to minimize the variability in cash flows due to fluctuations in foreign currency exchange rates, commodity prices, or interest rates?',
    'Why is the Asia Pacific reporting unit considered at risk of future goodwill impairment?',
]
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]
