SentenceTransformer based on bau0221/ptz_embedding

This is a sentence-transformers model finetuned from bau0221/ptz_embedding. It maps sentences & paragraphs to a 384-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("bau0221/ptz_embedding_ver3")
# Run inference
sentences = [
    'group1 put Abigail on the right side',
    'Move Charlotte to the right on Camera 4',
    'Set Evelyn at the right side on Camera 1',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 384]

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities.shape)
# [3, 3]
