Compact course on “Stochastic Approximation: A Dynamic View” Speaker : Prof. V.S. stability of the iterates. 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. These assumptions were consistent with those developed in [4]. 2, No. 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’.

The arguments above loosely follow the excellent text of Borkar. In this paper the stability theorem of Borkar and Meyn is extended to include the case when the mean field is a differential inclusion.

Robustness of Stochastic Approximation Algorithms Dynamic Stochastic Approximation Notes and References 3. This algorithm is a stochastic approximation of a continuous-time matrix exponential scheme which is further regularized by the addition of an entropy-like term to the problem's objective function.
