An integrated image visibility graph and topological data analysis for extracting time series features

Singh, Manoj K.; Chaube, Shshank; Pant, Sangeeta; … - In: Decision analytics journal 8 (2023), pp. 1-8

A time series can often be characterized using machine learning techniques, which require feature vectors as input. The quality of the feature vectors reflects the accuracy of the utilized machine learning techniques. We propose a method for combining features extracted from two popular...

A Partition-and-Merge Algorithm for Solving the Steiner Tree Problem in Large Graphs

Wu, Xinyu; Zhou, Yi; Hao, Jin-Kao; Fu, Zhang-Hua - 2023

The Steiner tree problem aims to determine a minimum edge-weighted tree spanning a given set of terminal vertices from a given graph. As a popular model for numerous practical applications, the problem has been the object of two important competitions (the 11th DIMACS Challenge in 2014 and the...
