WebApr 13, 2024 · Practical engineering problems are often involved multiple computationally expensive objectives. A promising strategy to alleviate the computational cost is the variable-fidelity metamodel-based multi-objective Bayesian optimization approach. However, the existing approaches are under the assumption of independent correlations … WebDec 29, 2016 · After all this hard work, we are finally able to combine all the pieces together, and formulate the Bayesian optimization algorithm: Given observed values f(x), update the posterior expectation of f using the GP model. Find xnew that maximises the EI: xnew = arg max EI(x). Compute the value of f for the point xnew.
