Optuna
Optuna is an open-source automatic hyperparameter optimization framework developed by Preferred Networks of Japan, used primarily for hyperparameter search and tuning of machine learning models. Key characteristics include a Define-by-Run dynamic search space design, support for multiple sampling algorithms such as TPE and CMA-ES, pruning strategies, and visualization analysis tools. Optuna supports integration with mainstream machine learning frameworks and is applicable to model optimization tasks in both research and production environments.
Timeline (last 90 days)
The study selected four hyperparameter optimization strategies: genetic algorithm, Hyperband, Optuna, and SMAC3
For hyperparameter tuning in an undergraduate thesis, it is recommended to use grid search combined with a small amount of manual adjustment, without needing to use automated tuning frameworks such as Optuna.
The Optuna team released Rustuna, a Rust implementation of the Optuna hyperparameter optimization framework.
Optuna implements optimization algorithms such as TPE, CMA-ES, and Grid Search, and uses a pruning mechanism to early-terminate unpromising trials.
Preferred Networks developed the deep learning framework Chainer, the Optuna hyperparameter optimization framework, and the distributed deep learning library ChainerMN.
Optuna implements multiple optimization algorithms including TPE, CMA-ES, and Grid Search.
Optuna adopts a Define-by-Run API design, allowing users to dynamically define search spaces in code.
Rustuna maintains a fully compatible API design with the original Optuna.
Optuna is a hyperparameter optimization framework open-sourced in 2018 by Japan's Preferred Networks.
The Optuna team officially released Rustuna, a Rust implementation of Optuna.
