Graph reconstruction from random-walk co-visitation: Geometric, empirical, and controlled networks
Marko Imbrišak, Krešimir Tisanić
Reconstructing an unknown graph from the trajectory of a random walk arises both for spatial correlation networks in astrophysics and for connectivity inference in network science.…

Information Geometry meets Functional ANOVA: An Exact Fisher-Information Decomposition, with an Application to Radio Luminosity Functions
Marko Imbrišak, Krešimir Tisanić
Information geometry represents a fitted model as a manifold whose metric is the Fisher information. We show that, for a nonlinear regression model, this metric decomposes exactly…

The VLA-COSMOS 3 GHz Large Project: Average radio spectral energy distribution of active galactic nuclei
Krešimir Tisanić, V. Smolčić, M. Imbrišak +5
As the SKA is expected to be operational in the next decade, investigations of the radio sky in the range of 100 MHz to 10 GHz have become important for simulations of the SKA obse…
