Scalable, fidelity-preserving topology for large and streaming data

Design algorithms and workflows that reduce the computational cost of computing persistent homology and related topological summaries on large-scale or streaming datasets while preserving the structural fidelity that makes these summaries scientifically meaningful for complex-systems monitoring and analysis.

Background

Topological analyses in complex systems often require repeated or streaming computations (e.g., sliding windows, online monitoring), making computational cost a practical bottleneck.

Although there have been major algorithmic advances, the authors stress that real-time deployment and repeated-window settings remain challenging, especially when interpretability requires identifying stable representatives.

They call for methods that are both operationally feasible and faithful to the structural signals of interest.

The open problem is therefore twofold: how to reduce the computational cost of topology on large or streaming data, and how to do so without sacrificing the structural fidelity that makes topology scientifically valuable in the first place.
