Synthetic Data vs. Real Plant Data: Who Trusts the Training Set?

Part I asked whether the model understands physics. Part II asks which data you trust about what it learned. “Trained on synthetic data” says how a model learned, not whether it may run, and a training set and an acceptance set do two different jobs. Blur them and you send a model to the line that passed every test except the ones the line would have given it.

Synthetic data is for coverage: rare faults, class balance, development before production data exists, edge cases you won’t stage live. Real plant data is for truth: evaluation, acceptance, drift detection. The evidence supports…
