Choose RoBO if…
- License: RoBO is BSD-3-Clause, optuna is MIT.
- Tags unique to RoBO: bayesian-optimization, gaussian processes, random forests.
- For tasks requiring robust handling of noisy data in Bayesian Optimization
When NOT to use RoBO
- Avoid if your project strictly requires open-source licenses other than BSD-3-Clause
- Not suitable for users not comfortable installing external dependencies manually
Choose optuna if…
- License: optuna is MIT, RoBO is BSD-3-Clause.
- Tags unique to optuna: distributed, hyperparameter-optimization, machine-learning, parallel.
- When you need to streamline the hyperparameter tuning process for machine learning models built in Python.
When NOT to use optuna
- If your project is not compatible with Python, as Optuna does not support other languages directly out of box.
- Projects requiring manual control over every aspect of hyperparameter tuning might find Optuna too automated for their needs.
