Researchers have developed a novel method for creating synthetic data to train neural machine translation models for low-resource Indigenous languages, specifically Q'eqchi' Mayan. This approach uses dictionaries to generate a large corpus, which is then used with Parameter-Efficient Fine-Tuning (PEFT) on an mT5-base model. While the synthetic data effectively teaches grammatical structure, achieving a BLEU score of 42.02, it struggles with lexical grounding and natural language fluidity, resulting in a much lower BLEU score of 0.59 when evaluated against organic text. The study suggests that synthetic data serves as a strong structural primer but requires authentic data for semantic refinement through curriculum learning. AI
