“…A general process of autoencoders/variational autoencodersbased design [131,264,265] is shown in Figure 21a. Taking microstructure images as the input, the encoder generates parametric latent features as the microstructure design variables.…”

“…Taking microstructure images as the input, the encoder generates parametric latent features as the microstructure design variables. Furthermore, the latent feature-property relationship is established by another machine learning model, such as Gaussian regression for Bayesian optimization, [264] convolutional residual network (ResNet), [131] etc. Microstructure design was done by searching latent feature values that lead to optimal material properties, and then mapping the optimal microstructure design from the latent space to the geometry space by decoding.…”

“…Most importantly, CNN-based models are prone to model overfit due to their large number of tunable parameters. Despite these limitations, recent work has demonstrated the positive impact of data-driven methods on topology optimization (Kollmann et al, 2020;Yilin et al, 2021) and inverse design of microstructures (Jung et al, 2020;Tan et al, 2020).…”

“…We note that problem formulations based on Bayesian Optimization [11,12,13]) account for uncertainty in the objective solely due to the imprecision of the surrogate and not due to the aleatoric, stochastic variability of the underlying microstructure. In the context of optimization/design problems in particular, a globally-accurate surrogate would be redundant.…”
