What is Bayesian Optimization and how does it work?

Bayesian Optimization is a strategy for optimizing objective functions that are expensive to evaluate. It uses a probabilistic model to predict the performance of different inputs and iteratively refines its predictions based on observed results.

What are the advantages of using Bayesian Optimization?

Some advantages include its efficiency in finding optimal solutions with fewer evaluations, its ability to handle noisy data, and its flexibility in incorporating prior knowledge.

Can you give me an example of where Bayesian Optimization is applied?

Sure! It's commonly used in hyperparameter tuning for machine learning models, where it helps to find the best set of parameters to improve model performance.

What are some common algorithms used in Bayesian Optimization?

Common algorithms include Gaussian Processes, Tree-structured Parzen Estimators (TPE), and Expected Improvement (EI) criteria.
