finetuned-bge-base-en

SentenceTransformer based on BAAI/bge-base-en

This is a sentence-transformers model finetuned from BAAI/bge-base-en. 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("llazio/finetuned-bge-base-en")
# Run inference
sentences = [
    '\nName : SMRT\nCategory: Public Transportation, Transit Services\nDepartment: Sales\nLocation: Los Angeles, CA\nAmount: 85.0\nCard: Sales Team Travel Budget\nTrip Name: unknown\n',
    '\nName : Elastic Habitat Solutions\nCategory: Cloud Enhancement Services, Data Analytics Tools\nDepartment: IT Operations\nLocation: London, UK\nAmount: 1489.57\nCard: Scalable Data Initiative\nTrip Name: unknown\n',
    '\nName : Wellness Haven\nCategory: Employee Health Programs, Professional Development\nDepartment: HR\nLocation: Munich, Germany\nAmount: 762.35\nCard: Corporate Wellness Initiatives\nTrip Name: unknown\n',
]
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]
