  • Statistical Inference Without Excess Data Using Only Stochastic Gradients Volume 2
    Statistical Inference Without Excess Data Using Only Stochastic Gradients: Volume 2
    Li, Tianyang ;
    Liu, Liu
    2020-08-01 | PDF
    We present a novel statistical inference framework for convex empirical risk minimization, using approximate stochastic Newton steps. The proposed algorithm is based on the notion of finite differences and allows the approximation of a Hessian-vector product from first-order information. In theory, our method efficiently computes the statistical er ...
