Chromatic symmetric functions and combinatorial polynomials are central constructs in modern algebraic combinatorics, extending classical graph invariants into rich algebraic frameworks. Originating ...
Abstract: This paper introduces Polynomial Graphical Lasso (PGL), a new approach to learning graph structures from nodal signals. Our key contribution lies in modeling the signals as Gaussian and ...
Abstract: Graph filters are essential tools in graph signal processing (GSP), which has been widely employed to process irregular data from sensor, social, brain, and transportation networks. This ...
