What is Statistical Topology and Inference?
Statistical Topology and Inference develops statistical methods for inference on topological summaries of data, including confidence bands, stability guarantees, and hypothesis testing in persistent homology.
Researchers address stability of persistent homology under noise (Carlsson, 2009; 2185 citations) and computational pipelines for topological features (Otter et al., 2017; 702 citations). Methods include randomization techniques (Diaconis and Sturmfels, 1998; 634 citations) and barycenter computations for shape averaging (Cuturi and Douc, 2013; 462 citations). Over 10 key papers from 1998-2018 establish foundations with thousands of citations.
Why It Matters
Statistical guarantees enable reliable hypothesis testing on topological features in high-dimensional data from neuroscience (Giusti et al., 2016; 409 citations) and biomolecular modeling (Cang and Wei, 2017; 333 citations). Confidence bands on persistence diagrams support shape comparison in point clouds (Carlsson, 2014; 239 citations), impacting data-driven science. These tools validate TDA pipelines against noise and multiple testing, as in planted partition estimation (Mossel et al., 2014; 300 citations).
Key Research Challenges
Stability Under Noise
Persistent homology features degrade under data perturbations, requiring bottleneck and Wasserstein stability theorems. Carlsson (2009) outlines instability in high dimensions. Cuturi and Douc (2013) address averaging via barycenters.
Randomization Methods
Generating null distributions for topological summaries demands efficient sampling from conditional spaces. Diaconis and Sturmfels (1998) provide algebraic Markov chains for exponential families. Applications include permutation tests in TDA.
Multiple Testing Control
TDA pipelines produce numerous persistence features needing FDR control. Otter et al. (2017) roadmap persistent homology computation but lacks integrated testing. Giusti et al. (2016) highlight simplex-level inference challenges.
