Graphical representation of the DNN based multi-fidelity surrogate model. In the experiments, we used three synthetic benchmark tasks to evaluate our method. The global maximum is -0.3979 at ( π, 12 .275) The materials are parameterized by three properties, Y oung's modulus (in To compute the frequency, we discretize the plate with quadratic tetrahedral elements (see Figure 1). The plate discretized with quadratic tetrahedral elements (the maximum mesh edge length is 1 .
