Runnable reproduction of the BYU group's released Curie-temperature random-forest model (github.com/msg-byu/ML-for-CurieTemp-Predictions, commit 80841ce4) run on 2026-09-24 in the Ouro sandbox: their 67/33 recipe, the train-DS1 test-DS2 generalization test, leave-one-composition-out predictions for seven measured magnet anchors, and a 100-composition leave-one-out calibration of their published low-Tc/high-Tc bias claim.
