Black‐box optimization refers to the process in which there is a complete separation between the evaluation of the objective function —and perhaps other functions used to enforce constraints— and the solution procedure, as illustrated in Figure 1. In simulation‐optimization, the black boxBlack-box optimization (BBO) aims to optimize an objective function by iteratively querying a black-box oracle in a sample-efficient way. While prior studies focus on forward approaches to learn surrogates for the unknown objective function, they struggle with steering clear of out-of-distribution and invalid inputs.Fitness Company Reimagines AV Content Distribution System to Engage and Inform Customers.

A metric that can quantify the improvement in the true BSMS objective value over fewer black-box function evaluations is more appropriate in the context of BBO. Area Under the Curve has been used in black-box optimization to measure how quickly an algorithm improves solution quality compared to other algorithms (Dewancker et al., 2016).Prior & Posterior: Before any observations, the distribution defined byK and µ = 0 forms the prior distribution. Given a set of observations (X,F), the prior is updated to form the posterior distribution over the candidate functions. Figure 1 shows the distribution of candidates and the mean surrogate model of an example f.Practical problems in science and engineering often involve optimizing a black-box objective function that is expensive to evaluate, such as neural network architecture design (Zoph and Le, 2016), robotics (Tesch et al., 2013), and molecular design (Sanchez-Lengeling and Aspuru-Guzik, 2018).How to achieve a near-optimal solution while minimizing function evaluations is thus a .
