Topological data analysis time series
WebMay 1, 2024 · Abstract. Topological Data Analysis (TDA) is a novel new and strong-growing method to deal with various data in most areas. And Persistent Homology is one of the most pivotal tools in Topological Data Analysis to acquire topological properties of the data. This article is based on the main mathematics behind Topological and Topological Data ... WebFeb 1, 2024 · Our methodology is based on topological data analysis (TDA). We use persistence homology to detect and quantify topological patterns that appear in multidimensional time series. Using a sliding window, we extract time-dependent point cloud data sets, to which we associate a topological space.
