Sub-Sampled Newton Methods I: Globally Convergent Algorithms

  title={Sub-Sampled Newton Methods I: Globally Convergent Algorithms},
  author={Farbod Roosta-Khorasani and Michael W. Mahoney},
Large scale optimization problems are ubiquitous in machine learning and data analysis and there is a plethora of algorithms for solving such problems. Many of these algorithms employ sub-sampling, as a way to either speed up the computations and/or to implicitly implement a form of statistical regularization. In this paper, we consider second-order iterative optimization algorithms and we provide bounds on the convergence of the variants of Newton's method that incorporate uniform sub-sampling…

Under certain assumptions, it is shown that the constrained optimization algorithm attains a composite convergence rate that is initially quadratic and asymptotically linear and validate its performance through widely encountered optimization tasks on several real and synthetic datasets by comparing it to classical optimization algorithms.

Exact and Inexact Subsampled Newton Methods for Optimization

This paper analyzes an inexact Newton method that solves linear systems approximately using the conjugate gradient (CG) method, and that samples the Hessian and not the gradient (the gradient is assumed to be exact).

Newton-Stein Method: An Optimization Method for GLMs via Stein's Lemma

This work proposes an alternative way of constructing the curvature information by formulating it as an estimation problem and applying a Stein-type lemma, which allows further improvements through sub-sampling and eigenvalue thresholding and achieves the highest performance compared to various algorithms on several datasets.

Fast and Furious Convergence: Stochastic Second Order Methods under Interpolation

Stochastic second-order methods for minimizing smooth and strongly-convex functions under an interpolation condition satisfied by over-parameterized models are considered and the regularized subsampled Newton method (R-SSN) achieves global linear convergence with an adaptive step-size and a constant batch-size.

This work motivates the extension of Newton methods to the SA regime, and argues for the use of the scalable low rank saddle free Newton (LRSFN) method, which avoids forming the Hessian in favor of making a low rank approximation.
