AfriNLLB-train-distilled Dataset

AfriNLLB is a series of efficient multilingual open-source models for African languages. AfriNLLB-train-distilled is one of two datasets we curated and used for training AfriNLLB models. We created AfriNLLB-train-distilled through knowledge distillation, translating the authentic dataset AfriNLLB-train with NLLB-200 3.3B. More details about data sources and processing can be found in the paper.

Supported Languages

AfriNLLB supports 15 language pairs (30 translation directions), including Swahili, Hausa, Yoruba, Amharic, Somali, Zulu, Lingala, Afrikaans, Wolof, and Egyptian Arabic, as well as other African Union official languages such as Arabic (MSA), French, Portuguese, and Spanish. Our training data covers bidirectional translation between English and 13 languages, and between French and two languages (Lingala and Wolof).
