Bayesian optimization is a method that allows computers to automatically find the best settings for complex problems.
Imagine you want to find the best recipe for a cake, but baking takes a long time and you want to make as few attempts as possible.
Bayesian optimization helps to smartly decide which ingredients and quantities you should try next to quickly achieve a good result.
It uses probabilities to learn from previous attempts and better plan the next steps.
This makes it especially useful when testing is expensive or time-consuming.
