Critique 1

Super interesting article! some minor feedback points,

• You can maybe start with an example where someone might be needing bayesian optimzation to better motivate the article.
• Maybe correct the definition of a black box function or specify that it is specific to bayesian optimization. Do all black box functions map from R^d to R? Not super certain about this statement.
• Could you introduce what objective functions in BO look like before the surrogate model section? Maybe give an example to further make it easier for the reader to get it.
• Adding to David’s points about EI, could you explain how the first term signify exploitation and second term exploration?
