S. Pidstryhach of the National Academy of Sciences of Ukraine popup.description1 Investigation of the sparse graph Laplacian estimation problem, as well as its generalization to complex- and quaternion-valued directed, undirected, mixed Laplacian graphs, with the aim of using them for applications where strongly connected feature tuples (or vectors) are considered as complex signals, RGB values images or three-dimensional locations of points in space popup.nrat_date 2024-12-09 Close
