第25回 MaDIS研究交流会

This talk will be focusing on our effort of employing Topological Data Analysis (TDA) methods to the various aspects of materials science research. We will start off by introducing the ideas of topology and how they can be applied as a tool for data analysis. Two different scheme will be introduced, namely: grid data and point cloud data. Case study examples will be presented including applying TDA to Atom Probe Tomography data to identify precipitates and how to use TDA to uncover hidden relationships in a dataset. Finally, we will introduce the idea of Hirshfeld surface and showcase how we can harness the information contained in a Hirshfeld surface and build a “Material Barcode” from it.
