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("ernestobs7/caregiver-ft-v1")
# Run inference
sentences = [
    'Does having a risk factor guarantee that a person will develop a disorder?',
    "A risk factor is a condition or behavior that occurs more frequently in those who have a disease, or who are at greater risk of getting a disease, than in those who don't have the risk factor. Having a risk factor doesn't mean a person will develop a disorder, and not having a risk factor doesn't mean you won’t. Risk factors for ALS include:",
    'possible decline in quality of life. \n \nBut despite these risks, family caregivers of any age are less likely than \nnon-caregivers to practice preventive healthcare and self-care behavior.  \nRegardless of age, sex, and race and ethnicity, caregivers report problems \nattending to their own health and well-being while managing caregiving \nresponsibilities. They report: \n• sleep deprivation  \n• poor eating habits  \n• failure to exercise  \n• failure to stay in bed when ill  \n• postponement of or failure to make medical appointments .',
]
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]
