Bayesian optimization framework enhances genetic algorithm hyperparameter tuning for materials science

By PulseAugur Editorial · [2 sources] ·

Researchers have developed a multi-fidelity framework to optimize genetic algorithm (GA) hyperparameters for lattice material design. This framework uses a combination of high-fidelity Fast Fourier Transform (FFT) homogenization, a medium-fidelity 3D convolutional neural network, and a low-fidelity Gaussian process within a Bayesian optimization (BO) approach. The study found that the logNEI acquisition function was most effective, and a penalized BO objective reduced the number of required lattices while maintaining performance. This optimized approach achieved comparable elastic modulus values with a 25-generation GA run to a full 75-generation run, reducing computational cost by 24% and eliminating the need for lattice mutation. AI
