Topological flow data analysis for transient flow patterns: a graph-based approach
Takashi Sakajo, Takeshi Matsumoto, Shizuo Kaji +2
We introduce a method of time series analysis for two-dimensional transient flow patterns based on Topological Flow Data Analysis (TFDA), a new approach to topological data analysi…
