SentenceTransformer based on FacebookAI/xlm-roberta-large
🚀 This v2.0 from the previously released version of omarelshehy/arabic-english-sts-matryoshka
📊 Metrics (MTEB) in this version are better especially on ar-en metrics, but again don't just rely on them — test the model yourself and see if it fits your needs! ✅
Model description
This is a Bilingual (Arabic-English) sentence-transformers model finetuned from FacebookAI/xlm-roberta-large. It maps sentences & paragraphs to a 1024-dimensional dense vector space and can be used for semantic textual similarity, semantic search, paraphrase mining, text classification, clustering, and more.
The model handles both languages separately 🌐, but also interchangeably, which unlocks flexible applications for developers and researchers who want to further build on Arabic models! 💡
- Model Type: Sentence Transformer
- Base model: FacebookAI/xlm-roberta-large
- Maximum Sequence Length: 512 tokens
- Output Dimensionality: 1024 tokens
- Similarity Function: Cosine Similarity
Matryoshka Embeddings 🪆
This model supports Matryoshka embeddings, allowing you to truncate embeddings into smaller sizes to optimize performance and memory usage, based on your task requirements. Available truncation sizes include: 1024, 768, 512, 256, 128, and 64
You can select the appropriate embedding size for your use case, ensuring flexibility in resource management.
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
matryoshka_dim = 786
model = SentenceTransformer("omarelshehy/arabic-english-sts-matryoshka-v2.0", truncate_dim=matryoshka_dim)
# Run inference
sentences = [
"She enjoyed reading books by the window as the rain poured outside.",
"كانت تستمتع بقراءة الكتب بجانب النافذة بينما كانت الأمطار تتساقط في الخارج.",
"Reading by the window was her favorite thing, especially during rainy days."
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 1024]
# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities.shape)
# [3, 3]
