This is a sentence-transformers model finetuned from Snowflake/snowflake-arctic-embed-l. It maps sentences & paragraphs to a 1024-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("bharath25911/travel_advisory-ft")
# Run inference
sentences = [
    'What are the recommended methods for cleaning your hands to reduce the spread of infectious diseases?',
    'cleaning your hands regularly with soap and water for at least 20 seconds, or using hand sanitizer containing at least 60% alcohol\ncovering your coughs and sneezes with a tissue or your elbow, not your hands\n\nMass gatherings (large-scale events)Clean your hands to help reduce the spread of infectious diseasesRespiratory infectious diseases: How to reduce the spread with personal protective measures\nTo lower your risk of getting sexually transmissible infections (STIs), HIV, and mpox, you can:\n\nget vaccinated against mpox if you’re eligible\nhave fewer sexual partners\nuse protection during sexual activity, like condoms and dental dams.',
    'To reduce your risk of getting sick, avoid contact with animals like stray dogs, livestock (such as pigs and cows), monkeys, snakes, rodents, birds, and bats.

embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 1024]

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