WebTopological Data Analysis (TDA) is a developing branch of data science which uses statistical learning and techniques from algebraic topology, such as persistent homology, … WebNov 7, 2024 · Topological data analysis (TDA) allows a characterization of time-series data obtained from complex dynamical systems. In this paper, we present a pattern changing detection technique based on TDA. Given a time series, the signal is divided in non-overlapped slicing windows.
WebApr 11, 2024 · To fill the gap between time series data analysis and complex network theory, the main objective is to capture spatio-temporal patterns of TBM dynamic excavation behavior from a topological structure perspective, which can provide valuable insights into geological information and over excavation ratio for intelligent tunneling project … WebMar 1, 2024 · In this paper, we present a new chaos detection method which utilizes tools from topological data analysis. Bi-variate density estimates of the randomly projected time series in the p-q plane described in Gottwald and Melbourne’s approach for 0–1 detection are used to generate a gray-scale image. We show that simple statistical summaries of ...
