BGE base Financial Matryoshka

Name: bge-base-financial-matryoshka
Rating: 2.5 (27 reviews)

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("cngcv/bge-base-financial-matryoshka")
# Run inference
sentences = [
    'After text generation, the process involves providing test data to NT Q, which then undergoes article correction, including dealing with fragmented articles and errors.',
    'What is the process for providing test data to NT Q after text generation?',
    'What is the significance of the dates in the text?',
]
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]

`The document lists several tasks with their statuses, such as "Done", "In progress", and "To be done". These statuses indicate the current progress of each task within the project. For example, "Set up environment" and "Set up development environment" are marked as "Done", suggesting these tasks have been completed, while "Build translation data set" is marked as "In progress", indicating it is currently being worked on.`	`What is the status of the project tasks mentioned in the document?`
`The 'Web Application Construction' task is mentioned to be completed by NT Q, with a duration from July 17, 2023, to July 28, 2023, and is marked as 'Done' with a completion of 10 tasks.`	`What is the scope of the 'Web Application Construction' task?`
`"RE F" could potentially stand for "Reference File" or "Record File," indicating that this text might be part of a larger dataset or document used for reference or record-keeping purposes.`	`What is the significance of the "RE F" at the beginning of the text?`
