Persistent Homology

Definition

Persistent homology is a mathematical technique derived from topological data analysis used to quantify and characterize the shape and structure of data. It identifies significant topological features, such as connected components, loops, or voids, that persist across varying scales or resolutions within a dataset. This method provides a robust way to extract meaningful structural information, even from noisy or high-dimensional data. It offers a powerful tool for understanding underlying patterns and connectivity.
