SentenceTransformer based on cambridgeltl/BioRedditBERT-uncased
This is a sentence-transformers model finetuned from cambridgeltl/BioRedditBERT-uncased. It maps sentences & paragraphs to a 768-dimensional dense vector space and can be used for retrieval.

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 = [
'The weather is lovely today.',
"It's so sunny outside!",
'He drove to the stadium.',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 768]
# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities)
# tensor([[1.0000, 0.8651, 0.7998],
# [0.8651, 1.0000, 0.7253],
# [0.7998, 0.7253, 1.0000]])
