SentenceTransformer based on vinai/phobert-base-v2
This is a sentence-transformers model finetuned from vinai/phobert-base-v2. 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_stage1")
# Run inference
sentences = [
'cửa_hàng quà tặng ở chân cầu giữa hai tòa nhà cung_cấp một lựa_chọn tuyệt_vời về những kỷ_niệm chất_lượng bản_sao và áp_phích của văn_hóa_nara',
'Cửa_hàng quà tặng có rất nhiều kỷ_niệm tuyệt_vời của nara .',
'Cửa_hàng quà tặng chỉ bán kẹo và bánh_nướng .',
]
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]
