New method slashes MNMT model size by 60% with no performance loss

Researchers have developed a novel framework to optimize multilingual neural machine translation (MNMT) models by pruning their vocabularies. This method significantly reduces memory and computational requirements by decreasing vocabulary size from over 128,000 to approximately 10,000 tokens, achieving up to 60% memory savings without performance degradation. Tested on models like M2M100, NLLB-200, and mBART-50 for English-Arabic translation, the optimized models demonstrated comparable or superior performance to dedicated bilingual baselines, particularly in semantic adequacy and fluency. AI

IMPACT This research offers a path to more efficient deployment of large multilingual translation models, potentially reducing infrastructure costs and enabling wider accessibility.
