WebAcquisition functions are heuristics employed to evaluate the usefulness of one of more design points for achieving the objective of maximizing the underlying black box function. BoTorch supports both analytic as well as (quasi-) Monte-Carlo based acquisition functions. It provides a generic AcquisitionFunction API that abstracts away from the ... WebThe Bayesian optimization "loop" for a batch size of q simply iterates the following steps: (1) given a surrogate model, choose a batch of points { x 1, x 2, … x q }, (2) observe f ( x) for each x in the batch, and (3) update the surrogate model. We run N_BATCH=75 iterations. The acquisition function is approximated using MC_SAMPLES=2048 samples.
