Technical Details

Architecture

The model is based on the Transformer architecture, which utilizes self-attention mechanisms to process and generate embeddings that capture contextual relationships between words in multiple languages.

Training Data

Text-multilingual-embedding-002 was trained on a diverse and extensive dataset that includes text from books, websites, and other multilingual sources. The training data encompasses approximately 1 billion sentences across various languages, ensuring a broad understanding of linguistic nuances.

Data Source and Size

The model was trained on a large-scale dataset. The diversity of the data contributes significantly to the model's ability to generalize across different languages and contexts.

Knowledge Cutoff

The model's knowledge is current as of March 2023.

Diversity and Bias

The training data includes a wide range of sources to minimize bias and improve robustness. However, like all models trained on large datasets, it may still reflect some inherent biases present in the data.

Performance Metrics

Massive Text Embedding Benchmark (MTEB)

The model's performance on the MTEB benchmark indicates high accuracy across multiple tasks, particularly in retrieval and classification scenarios. These metrics suggest that the model performs well in ranking relevant documents and retrieving information effectively from large datasets.

  • nDCG@10: 60.8
  • Recall@100: 92.4

The model has demonstrated a high level of robustness, effectively handling diverse inputs across different languages. It has been benchmarked against user-generated content (UGC) and has shown resilience in maintaining performance despite variations in language and structure.

Comparison with Other Models

Text-multilingual-embedding-002 has shown competitive performance against other leading multilingual embedding models. In the MTEB evaluation, it achieved:

  • Accuracy: 64.0 on average across various tasks.
  • Retrieval tasks: Strong performance, indicating its robustness in handling multilingual queries.

Text-multilingual-embedding-002 outperformed several models in the same category:

  • LaBSE (Language-agnostic BERT Sentence Embedding): 45.2
  • Cohere: 64.0
  • BGE (Best Generative Embedding): 64.2
