Abstract Scope |
Data efficient methods that actively learn and explore design spaces are critical for materials development due to the high cost associated with the acquisition of materials data. In this study, we introduce a framework that combines invertible neural networks (INNs) and Gaussian processes (GPs) to address this need. Our framework actively learns and provides valuable guidance on which simulations or experiments to perform. It possesses the capacity to capture intricate posterior distributions of solutions, while simultaneously supporting a wide range of design objectives. Moreover, it can quantify the if the model is supported for a specific design target. Our framework also achieves both computational efficiency and data efficiency in high dimensional spaces, thus minimizing the number of required simulations/experiments to be performed. This talk will go over the theoretical development of the framework and demonstrate its effectiveness by learning an inverse mapping from material anisotropy to texture. SAND2023-05883A |
