SentenceTransformer based on jinaai/jina-clip-v2

This is a sentence-transformers model finetuned from jinaai/jina-clip-v2. It maps sentences & paragraphs to a None-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("seregadgl/t12")
# Run inference
sentences = [
    'honor watch gs pro black ',
    'honor watch gs pro white ',
    'трансформер pituso carlo hb gy 06 lemon',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 1024]

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