Describe the basics of Bayesian methods for tuning hyperparameters. Explain how Bayesian optimization works and its advantages over other hyperparameter tuning methods.
Explanation:
Bayesian optimization is a powerful method for hyperparameter tuning that uses a probabilistic model to estimate the performance of a model with different hyperparameters. It iteratively selects hyperparameters to evaluate the model based on the probability of improving the current best performance. This allows Bayesian optimization to efficiently explore the search space and find the optimal hyperparameters with fewer evaluations compared to other methods. The probabilistic model used in Bayesian optimization can capture the uncertainty in the performance estimates, which helps in making better decisions about which hyperparameters to evaluate next.
