Mencoba

A controlled study of compact neural reranking for Sonja PhraseFlow. Two training objectives and three seeds are compared on the same 600 reused development cases, with learning curves, paired uncertainty intervals and native R/CPU verification. The findings support retaining the existing model. This is exploratory research, not an independent final-test accuracy claim. Author: Sonja Sahebzad, Utrecht, the Netherlands.
