Optuna is a versatile and promising tool for feature selection that uses Bayesian optimization techniques to efficiently search the parameter space and find the best feature combinations. The article provides a hands-on example of using Optuna for feature selection and compares it to other common strategies. ## Full article daily.dev links to this article rather than hosting it.
