Topological Feature Extraction of Scanty Time Series Data: A Data-Driven Approach for Dynamic State Change Detection

A methodology that combines Topological Data Analysis (TDA), specifically 0-D sublevel persistence, with Machine Learning (ML) classifiers to distinguish periodic and chaotic regimes directly from time series is proposed, providing an effective alternative for analysing sparse or incomplete time series.
