Multilingual Pre Trained Model
Multilingual pre-trained models (MPLMs) aim to create language models capable of understanding and processing multiple languages simultaneously, improving cross-lingual transfer learning and reducing the need for separate models for each language. Current research focuses on enhancing cross-lingual alignment, particularly across languages with different scripts, and improving performance on various downstream tasks like sentiment analysis, machine translation, and natural language inference, often employing architectures like mBART, XLM-R, and T5, as well as exploring ensemble methods and structured pruning techniques. These advancements significantly impact NLP research by enabling more efficient development of multilingual applications and facilitating research on low-resource languages, ultimately promoting broader access to NLP technology.
