On the rate of concentration of maxima in Gaussian arrays
Rafail Kartsioukas, Zheng Gao, Stilian Stoev
Recently in Gao and Stoev (2018) it was established that the concentration of maxima phenomenon is the key to solving the exact sparse support recovery problem in high dimensions.…
Fundamental Limits of Exact Support Recovery in High Dimensions
Zheng Gao, Stilian Stoev
We study the support recovery problem for a high-dimensional signal observed with additive noise. With suitable parametrization of the signal sparsity and magnitude of its non-zero…
Uncertainty in Economic Growth and Inequality
