sentence-transformers-usc26-bert

SentenceTransformer based on chandlerNick/USC26_Subtitle_Classification_BERT

This is a sentence-transformers model finetuned from chandlerNick/USC26_Subtitle_Classification_BERT. 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.

Note that it was fine tuned by training a linear projection to project from the pooler_output output attribute of BERT to one of 11 subtitle classes from the usc26. One can see more about this in the github project: https://github.com/chandlerNick/Tax_Law_RAG

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.shape)
# [3, 3]
