基于 sentence-transformers/all-MiniLM-L6-v2 的 SentenceTransformer
这是一个基于 sentence-transformers/all-MiniLM-L6-v2 微调的 sentence-transformers 模型。它将句子和段落映射到 384 维的稠密向量空间,可用于语义文本相似度、语义搜索、释义挖掘、文本分类、聚类等任务。

完整模型架构
SentenceTransformer(
(0): Transformer({'max_seq_length': 256, 'do_lower_case': False}) with Transformer model: BertModel
(1): Pooling({'word_embedding_dimension': 384, 'pooling_mode_cls_token': False, 'pooling_mode_mean_tokens': True, 'pooling_mode_max_tokens': False, 'pooling_mode_mean_sqrt_len_tokens': False, 'pooling_mode_weightedmean_tokens': False, 'pooling_mode_lasttoken': False, 'include_prompt': True})
(2): Normalize()
)
使用方法
直接使用 (Sentence Transformers)
首先安装 Sentence Transformers 库:
pip install -U sentence-transformers
然后你可以加载此模型并运行推理。
from sentence_transformers import SentenceTransformer
# 从 🤗 Hub 下载
model = SentenceTransformer("overfitting-co/A2P-constrastive-all")
# 运行推理
sentences = [
'Khaosan Road',
'Reserved',
'Adventurous',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 384]
# 获取嵌入的相似度分数
similarities = model.similarity(embeddings, embeddings)
print(similarities.shape)
# [3, 3]
