Group Cross-Correlations with Faintly Constrained Filters
Published 31 Dec 2025 in math.DS, cs.LG, and math.GR | (2601.00045v1)
Abstract: We provide a notion of group cross-correlations, where the associated filter is not as tightly constrained as in the previous literature. This resolves an incompatibility previous constraints have for group actions with non-compact stabilizers. Moreover, we generalize previous results to group actions that are not necessarily transitive, and we weaken the common assumption of unimodularity.
