The actor-critic algorithm of Barto and others for simulation-based optimization of Markov decision processes is cast as a two time Scale stochastic approximation. This example is taken from the very Stochastic approximation methods are a family of iterative methods typically used for root-finding problems or for optimization problems.

Vivek Shripad Borkar (born 1954) is an Indian electrical engineer, mathematician and an Institute chair professor at the Indian Institute of Technology, Mumbai. Stochastic Systems 2012, Vol. The arguments are given in a crude manner. (2017) A Generalization of the Borkar-Meyn Theorem for Stochastic Recursive Inclusions. 5.2 The Basic SA Algorithm The stochastic approximations (SA) algorithm essentially solves a system of (nonlinear) equations of the form h(µ) = 0 based on noisy measurements of h(µ). Search for more papers by this author (2017) A stability criterion for two timescale stochastic approximation schemes. One also has techniques based upon the contractive properties or homogeneity properties of the functions involved (see, e.g., [20] and [12], respectively). 3, pp. Although powerful, these algorithms have applications in control and communications engineering, artificial intelligence and economic modeling. Stability and convergence properties of stochastic approximation algorithms are analyzed when the noise includes a long range dependent component (modeled by a fractional Brownian motion) and a heavy tailed component (modeled by a symmetric stable process), in addition to the usual ‘martingale noise’. He is known for introducing analytical paradigm in stochastic optimal control processes and is an elected fellow of all the three major Indian science academies viz. Introduction. ∙ ERNET India ∙ 0 ∙ share . Książki Lit. A Generalization of the Borkar-Meyn Theorem for Stochastic Recursive Inclusions. In this paper, we give a generalization of a result by Borkar and Meyn (2000) 1], on the stability and convergence of synchronous-update stochastic approximation algorithms, to the case of asynchronous stochastic approximations with delays. We shorten the proof in several ways and consider convergence.
