Abstract Scope |
Researchers have demonstrated that data scientific and machine learning techniques, trained using available large datasets, can be used to rapidly accelerate the pace of technical innovation. Unfortunately, the lack of inexpensive data sources in Materials Informatics means that collecting datasets composed of statistically diverse material microstructures is extremely challenging. Here, we will demonstrate that statistically conditioned microstructure generative models provide a natural pathway to overcome this challenge. We propose a framework expanding on our recently proposed statistically conditioned Local-Global Decomposition generative models. The crux of the proposed framework is a novel suite of algorithms for generating salient 2-point statistics – without needing prior examples – for conditioning. We provide two demonstrations. First, we address the general dataset generation problem; we generate a general statistically diverse microstructure dataset of 2-phase composite microstructures. Second, we briefly discuss how dataset generation algorithms play a critical role in accelerating the extraction of process-structure models. |
