ModernBERT Embed base fitness health Matryoshka

This is a sentence-transformers model finetuned from kokojake/modernbert-embed-base-fitness-health-matryoshka-8-epochs on the json dataset. 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("kokojake/modernbert-embed-base-fitness-health-matryoshka-8-epochs-25k")
# Run inference
sentences = [
    'Low back pain is \nthe leading cause of \ndisability globally across \nall ages and in both \nsexes, representing 8% \nof all YLDs in 2020 (10).',
    'prevalence of low back pain by age and sex',
    'BMI calculation in postpartum studies',
]
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]
