WebAug 30, 2024 · TL;DR: Running HPO at scale is important and Ray Tune makes that easy. When considering what HPO strategies to use for your project, start by choosing a scheduler — it can massively improve performance — with random search and build complexity as needed. When in doubt, ASHA is a good default scheduler. Acknowledgements: I want to …

First, I would suggest to use tune.grid_search([0, 1]) instead of tune.choice([0, 1]).With choice you get a random seleciton - thus all trial could be a=0! (I had this when running your script). If you do this, set num_samples=2 to have 4 trials to run (2 times the full grid search). east corrimal tide and swellWebIn Tune, some hyperparameter optimization algorithms are written as “scheduling algorithms”. These Trial Schedulers can early terminate bad trials, pause trials, clone trials, and alter hyperparameters of a running trial. All Trial Schedulers take in a metric, which is a value returned in the result dict of your Trainable and is maximized ... eastcot close holbury
