I used a lot of these techniques as an operations research analyst in the early 2010’s. I also wondered the same thing about DoE for hyperparameter tuning. Always felt like it was a case of grid search/random search/bayes opt being “good enough” and easier. But maybe DoE would be worth it for something like LLMs where training runs for a month on 25k GPUs.
