Partial-field inferability of galaxy overdensity structure: An information-geometric account of incomplete sky coverage
Marko Imbrišak, Krešimir Tisanić
Structural statistics of the galaxy distribution are routinely measured on only partially observed fields, yet how much structure survives incomplete coverage, and which aspects ar…
Gram-Schmidt correlation bookkeeping for weighted FBET-type frameworks: separating short- and long-range correlation scales in correlated measurements, with an application to radio luminosity functions
Marko Imbrišak, Krešimir Tisanić
Uncertainty quantification for correlated measurements frequently requires a covariance model that mixes several qualitatively different correlation structures: local measurement n…
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…
