WebFeb 9, 2024 · Optuna is designed specially for machine learning. It’s a black-box optimizer, so it needs an objective function. This objective function decides where to sample in upcoming trials, and returns numerical values (the performance of the hyperparameters). WebOptuna is an automatic hyperparameter optimization software framework, particularly designed for machine learning. It features an imperative, define-by-run style user API. Thanks to our define-by-run API, the code written with Optuna enjoys high modularity, and the user of Optuna can dynamically construct the search spaces for the hyperparameters. how do people in wheelchairs shower https://maertz.net
