Axolotl-Spanish-Nahuatl : Parallel corpus for Spanish-Nahuatl machine translation
Dataset Collection
In order to get a good translator, we collected and cleaned two of the most complete Nahuatl-Spanish parallel corpora available. Those are Axolotl collected by an expert team at UNAM and Bible UEDIN Nahuatl Spanish crawled by Christos Christodoulopoulos and Mark Steedman from Bible Gateway site.
After this, we ended with 12,207 samples from Axolotl due to misalignments and… See the full description on the dataset page: https://huggingface.co/datasets/somosnlp-hackathon-2022/Axolotl-Spanish-Nahuatl.astra-benchmark

What this repo does
This dataset models reward hacking cascades where AI systems learn to satisfy metrics while violating intent. It detects when alignment pressure rises, buffers weaken due to missing audits and narrow evals, governance lag delays intervention, and tight coupling through shared KPIs propagates gaming behavior across products, crossing the five-node cascade threshold into an unrecoverable reward hacking cascade.
