SentenceTransformer based on TaylorAI/bge-micro-v2

This is a sentence-transformers model finetuned from TaylorAI/bge-micro-v2. It maps sentences & paragraphs to a 384-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 = [
    'Founded by some 30 leaders of the Christian Right, the Alliance Defending Freedom is a legal advocacy and training group that has supported the recriminalization of sexual acts between consenting LGBTQ adults in the U.S. and criminalization abroad; has defended state-sanctioned sterilization of trans people abroad; has contended that LGBTQ people are more likely to engage in pedophilia; and claims that a ‘homosexual agenda’ will destroy Christianity and society. ADF also works to develop “religious liberty” legislation and case law that will allow the denial of goods and services to LGBTQ people on the basis of religion. Since the election of President Trump, ADF has become one of the most influential groups informing the administration’s attack on LGBTQ rights.',
    'Fossil fuels have powered centuries of progress, lifted billions out of poverty, and remain the backbone of global energy, while alternatives, though promising, cannot yet match their scale, reliability, or affordability.',
    'Climate change is nothing more than a fabricated agenda pushed by corrupt elites, politicians, and scientists to control the masses, gain wealth, and suppress freedom.',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 384]

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities.shape)
# [3, 3]
