Abstract Scope |
Controllable generative models have emerged as a foundational cornerstone of modern Materials Informatics efforts. For example, these models allow researchers to systematically expand limited experimental datasets by injecting curated synthetic data into poorly represented regions of the microstructure statistics space. In this talk, we present the Local-Global Decomposition generative framework, a generative framework that provides 1- and 2-point statistical conditioning, can stably extrapolate, and requires (at most) only a single image for training. The framework utilizes statistical physics – specifically, a physics inspired decomposition – to stabilize the training and inference of a denoising diffusion model. In addition to presenting the proposed generative modelling framework, we present a series of examples – including both N-phase and polycrystalline systems – to explore its strengths and weaknesses. Finally, we discuss potential applications. |
