SentenceTransformer based on FacebookAI/roberta-base

This is a sentence-transformers model finetuned from FacebookAI/roberta-base. 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("bobox/RoBERTa-base-unsupervised-TSDAE")
# Run inference
sentences = [
    'beer wine both sugar alcohol excessive be a infections You also sweets, along with foods moldy cheese, if you prone.',
    "Since beer and wine both contain yeast and sugar (alcohol is sugar fermented by yeast), excessive drinking can definitely be a recipe for yeast infections. You should also go easy on sweets, along with foods like moldy cheese, mushrooms, and anything fermented if you're prone to yeast infections. 3.",
    'They began selling the plush animals to retailers rather than operating a store themselves. Today, Boyds is a publicly traded company that manufactures 18 million-20 million bears a year, all at a government-owned facility in China.',
]
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]
