EMMA-500: Enhancing Massively Multilingual Adaptation of Large Language Models

Model Description

EMMA-500 is a state-of-the-art multilingual language model designed to improve language representation, especially in low-resource languages, through continual pre-training on the Llama 2 7B architecture. Leveraging the MaLA Corpus, which spans over 500 languages and 74 billion tokens, EMMA-500 excels in multilingual tasks like commonsense reasoning, machine translation, open-ended generation, and text classification.

EMMA-500 outperforms other Llama 2-based models in diverse multilingual settings while maintaining robustness in specialized tasks.

Model Details

  • Architecture: Built on Llama 2 7B with enhanced language adaptation through continual pre-training.
  • Languages: Supports 546 languages with substantial training data (over 100k tokens each).
  • Data Mix: A diverse mix of text from domains like code, books, instruction data, and more.
  • Key Tasks: Commonsense reasoning, machine translation, text classification, natural language inference, code generation, and open-ended generation.

Data Access

Usage

You can use EMMA-500 for multilingual text generation. Below is an example to generate text using the model:

from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = "MaLA-LM/emma-500-llama2-7b"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(model_name)

input_text = "Once upon a time"
inputs = tokenizer(input_text, return_tensors="pt")
outputs = model.generate(**inputs)

print(tokenizer.decode(outputs[0], skip_special_tokens=True))

Model Performance

EMMA-500 was evaluated across multiple benchmarks and tasks, demonstrating:

  • Lowest negative log-likelihood in intrinsic evaluations.
  • Significant improvements in commonsense reasoning, machine translation, and open-ended generation.
  • Outperformed all Llama 2-based models in text classification and natural language inference.
  • Enhanced performance in code generation and machine reading comprehension (MRC).

Challenges remain in low-resource languages, where the model tends to have higher Self-BLEU scores, indicating reduced output diversity.
