Tune’s Search Algorithms integrate with Optuna and, as a result, allow you to seamlessly scale up a Optuna optimization process - without sacrificing performance.\n", "\n", "Similar to Ray Tune, Optuna is an automatic hyperparameter optimization software framework, particularly designed for machine learning. It features an imperative (\"how\" over \"what\" emphasis), define-by-run style user API. With Optuna, a user has the ability to dynamically construct the search spaces for the hyperparameters. Optuna falls in the domain of \"derivative-free optimization\" and \"black-box optimization\".\n", "\n", "In this example we minimize a simple objective to briefly demonstrate the usage of Optuna with Ray Tune via `OptunaSearch`, including examples of conditional search spaces (string together relationships between hyperparameters), and the multi-objective problem (measure trade-offs among all important metrics). It's useful to keep in mind that despite the emphasis on machine learning experiments, Ray Tune optimizes any implicit or explicit objective. Here we assume `optuna==2.9.1` library is installed. To learn more, please refer to [Optuna website](https://optuna.org/).\n", "\n", "Please note that sophisticated schedulers, such as `AsyncHyperBandScheduler`, may not work correctly with multi-objective optimization, since they typically expect a scalar score to compare fitness among trials.\n" ] }, { "cell_type": "code", "execution_count": 1, "id": "aeaf9ff0", "metadata": { "tags": [
