Composable core-sets for determinant maximization problems via spectral spanners
We study a generalization of classical combinatorial graph spanners to the spectral setting. Given a set of vectors V ⊆ ℝd, we say a set U ⊆ V is an α-spectral kspanner, for k ≤ d, if for all v ∈ V there is a probability distribution µv supported on U such that vv ≼k α· Eu∼µvuu, where for two matric...
