Google Vizier performs hyperparameter tuning. And makes cookies:
At the tail end of the paper we find something else very much of our times, and so very Google. If you ever find yourself in the Google cafeteria, try the cookies. The recipe for those cookies was optimised by Vizier, with trials sent to chefs to bake, and feedback on the trials obtained by Googler’s eating the results.
It has already proven to be a valuable platform for research and development, and we expect it will only grow more so as the area of black-box optimization grows in importance. Also, it designs excellent cookies, which is a very rare capability among computational systems.
