SentenceTransformer based on huudan123/model_stage3_latest

This is a sentence-transformers model finetuned from huudan123/model_stage3_latest. 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_stage4_v2_latest_new")
# Run inference
sentences = [
    'Tổng thống Ukraine Leonid Kuchma hôm nay đã cắt ngắn chuyến thăm Mỹ Latinh khi cuộc tranh cãi biên giới gay gắt giữa Ukraine và Nga ngày càng xấu đi.',
    'Mỹ, NATO dấy lên nghi ngại Nga rút khỏi biên giới Ukraine',
    'Một người đàn ông mặc áo khoác màu cam nói chuyện với một người khác khi họ đi bộ trong tuyết.',
]
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]
