Beyond the Shape of Data - Detecting Spatial Interactions

Explore advanced topological data analysis techniques in this conference talk that extends beyond traditional shape detection to characterize spatial interactions between multiple data subsets. Learn about the innovative mixup barcode tool, developed through collaborative research with N. Arustamyan, M. Wheeler and P. Bubenik, which addresses challenges in deep learning model training by analyzing how different data subsets interact spatially rather than focusing solely on individual data shapes.
