Abstract Scope |
Many problems in Materials Science are ill-posed, meaning that, given a task there may be one, many, or no possible solutions. Classic examples of ill-posed problems include materials design and microstructure reconstruction, where a user may be interested in obtaining a microstructure which corresponds to a desired property or structural descriptor. When solving inverse problems, the existence (or lack thereof) of multiple solutions presents a persistent problem in high dimensional spaces, where the set of possible solutions becomes incredibly vast and difficult to enumerate. New algorithms utilizing generative priors provide a promising avenue for regularizing these high dimensional ill-posed problems. This talk will discuss the theory and benefits of generative priors, as well as demonstrate their practicality by solving materials design and microstructure reconstruction problems relating to 3D Polycrystalline RVE's. |
