  • SCOPE: Spectral Concentration by Distributionally Robust Joint Covariance-Precision Estimation

    SCOPE: Spectral Concentration by Distributionally Robust Joint Covariance-Precision Estimation arXiv:2511.14146v1 Announce Type: new Abstract: We propose a distributionally robust formulation for simultaneously estimating the covariance matrix and the precision matrix of a random vector.The proposed model minimizes the worst-case weighted sum of the Frobenius loss of the covariance estimator and Stein’s loss of the precision…
