WebMar 16, 2024 · We provide non-asymptotic convergence rates of various gradientbased algorithms; this includes the famous Stochastic Gradient (SG) descent (a.k.a. Robbins-Monro algorithm), mini-batch SG and time-varying mini-batch SG algorithms, as well as their iterated averages (a.k.a. Polyak-Ruppert averaging).
WebThe K-W scheme is a version of the Robbins-Monro stochastic approximation algorithm and incorporates balanced two-sided estimates of the gradient using two objective function measurements for a scalar parameter. When the parameter is an N -dimensional vector, the number of function measurements using this algorithm scales up to 2 N. WebThe main purpose of this study is to improve estimation efficiency in obtaining full-information maximum likelihood (FIML) estimates of contextual effects by adopting the Metropolis-Hastings Robbins-Monro algorithm (MH-RM; Cai, 2008, 2010a, 2010b).
