SentenceTransformer based on huudan123/model_stage1

This is a sentence-transformers model finetuned from huudan123/model_stage1. 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("huudan123/model_stage2")
# Run inference
sentences = [
    'hay na uy hay gì đó',
    'na uy hoặc từ một trong những quốc_gia scandinavia',
    'na uy hay cái gì đó khác',
]
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]
