Minimax detection of localized signals in statistical inverse problems

Authors Pohlmann M, Werner F, Munk A Journal arXiv Citation arXiv:2112.05648. Abstract We investigate minimax testing for detecting local signals or linear combinations of such signals when only indirect data is available. Naturally, in the presence of noise, signals that are too small cannot be reliably detected. In a Gaussian
