HeyDunaX/Tay_Embedding

SentenceTransformer based on AITeamVN/Vietnamese_Embedding_v2

This is a sentence-transformers model finetuned from AITeamVN/Vietnamese_Embedding_v2 on the tay-vietnamese-nmt dataset. It maps sentences & paragraphs to a 1024-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("HeyDunaX/Tay_Embedding")
# Run inference
sentences = [
    'Các',
    'bắc',
    'chân tay mập',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 1024]

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities)
# tensor([[ 1.0000,  0.3147, -0.0254],
#         [ 0.3147,  1.0000, -0.1489],
#         [-0.0254, -0.1489,  1.0000]])
