moe-girl-v2

SentenceTransformer based on BAAI/bge-small-zh-v1.5

This is a sentence-transformers model finetuned from BAAI/bge-small-zh-v1.5 on the json dataset. It maps sentences & paragraphs to a 512-dimensional dense vector space and can be used for retrieval.

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("johnyy212/moe-girl-v2")
# Run inference
sentences = [
    '熟女、A型、召唤能力者',
    '角色：文豪野犬:尾崎红叶\n本名：尾崎、红叶、Ozaki Kouyou\n别名：红叶大姐、红叶君\n声优：小清水亚美\n发色：红\n瞳色：红\n生日：1月10日\n星座：摩羯\n血型：A\n萌点：和服、遮眼发、超能力者、熟女',
    '文豪野犬:尾崎红叶',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 512]

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities)
# tensor([[ 1.0000,  0.3878, -0.0819],
#         [ 0.3878,  1.0000,  0.0236],
#         [-0.0819,  0.0236,  1.0000]])
