What changed

Combined low-resource language data mining and sparsely gated translation models with FLORES-200 evaluation across a large set of language directions.

Scientific scope

Combined low-resource language data mining and sparsely gated translation models with FLORES-200 evaluation across a large set of language directions. Integrated translation-and-evaluation package, not an invention of mixture-of-experts. Translation quality and toxicity metrics are benchmark-specific, not equal quality across every language.

Evidence

The linked original sources describe the stated contribution and its evidence limits. WRS has not independently rerun the experiments or certified a proof. Integrated translation-and-evaluation package, not an invention of mixture-of-experts. Translation quality and toxicity metrics are benchmark-specific, not equal quality across every language.
