Optuna

Optuna is the automatic hyperparameter optimization framework: it uses state-of-the-art algorithms to find optimal hyperparameter values fast.

Optuna is the automatic hyperparameter optimization framework you need for machine learning: it accelerates model tuning. The platform features a novel Define-by-Run API, ensuring high code modularity and dynamic search space construction. It employs state-of-the-art algorithms, like Tree-structured Parzen Estimator (TPE), to efficiently sample hyperparameters and prune unpromising trials, significantly outperforming traditional methods like GridSearch. For speed, Optuna supports easy, asynchronous distributed optimization, allowing studies to scale across tens or hundreds of workers with minimal code changes.
