SentenceTransformer based on google-bert/bert-base-uncased

This is a sentence-transformers model finetuned from google-bert/bert-base-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:

bash
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("omkar334/bert-base-uncased-retromae")
# Run inference
sentences = [
    'A kid throwing axes at targets in a competition.',
    'The audit steps in this section should be used to assess the potential risks posed by the lack of management or user support.',
    'This photograph is happy',
]
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, 0.5798, 0.5999],
#         [0.5798, 1.0000, 0.5697],
#         [0.5999, 0.5697, 1.0000]])
