agentlans / multilingual-e5-small-aligned-v2

SentenceTransformer based on agentlans/multilingual-e5-small-aligned

This is a sentence-transformers model finetuned from agentlans/multilingual-e5-small-aligned . It maps sentences & paragraphs to a 384-dimensional dense vector space and can be used for semantic textual similarity, semantic search, paraphrase mining, text classification, clustering, and more.

• One of the smallest multilingual embedding models on Huggingface
• This model is aligned which means translations have similar embeddings compared to unrelated sentences
• Finetuned on 1,000,000 randomly selected sentence pairs downloaded from Tatoeba 2024-09-26
  • Includes pairs where one or both sentences are non-English
  • For each pair, two negative examples were generated

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("agentlans/multilingual-e5-small-aligned-v2")
# Run inference
sentences = [
    'Esta es mi amiga Rachel, fuimos al instituto juntos.',
    "Je n'ai pas encore pris ma décision.",
    'When applying to American universities, your TOEFL score is only one factor.',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 384]

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities.shape)
# [3, 3]
