Hyperparam tuning that has better intuition and can incorporate architecture changes automatically. It won't invent something completely new though.
Probably would cut the number of runs down by a significant number (as far as I can tell it's doing a grid search once it decides to mess with a knob or section of the architecture).
I don't necessarily disagree, but am wondering whether you have any particular reason/intuition driving you to claim this. I have seen AI agents be quite creative in other tasks; do you think there's a particular reason why we shouldn't see creativity in architecture research, given enough time and resources?
