Abstract Scope |
Of the many high dimensional problems in materials models, macroscopic properties of mesoscopic grain boundary defect networks present a difficult model to optimize with current methods. Copious local minima lower the reliability of common numerical techniques, and global methods sacrifice efficiency to solve said reliability. Machine learning applications are appealing in this case, but need either long unsupervised training times, or a training set of gold standard data. We have created and utilized a video game to obtain both insights into human intuition on the optimization and training sets for neural networks. In this presentation we compare the performance of common global optimization methods, direct human input, and a human trained neural network on a grain boundary network optimization problem. |
