Topological Machine Learning in Material Science
Abstract:
Recent advances in material science have led to the era of enormous databases of materials for different applications. Analyzing and classifying such large and complex datasets is generally challenging. Topological data analysis, that builds on techniques from topology, is a natural fit for this application. Data analysis and classification involving persistence diagrams have been applied in numerous applications such as action recognition, handwriting analysis, shape study, image analysis, sensor network, and signal analysis. In this talk I will provide a brief introduction to topological data analysis, focusing primarily on persistence diagrams. Our goal is to provide a supervised machine learning algorithm, the classifier(?), on the space of persistence diagrams. This framework is applicable to a wide variety of datasets. I will present an application in material science, on classification of crystal structures of High Entropy Alloys.
