Mean-Field Learning: a Survey [article]

Hamidou Tembine, Raul Tempone, Pedro Vilanova
2012 arXiv   pre-print
Most of learning algorithms for games with continuous action spaces are limited to strict contraction best reply maps in which the Banach-Picard iteration converges with geometrical convergence rate.  ...  When the best reply map is not a contraction, Ishikawa-based learning is proposed. The algorithm is shown to behave well for Lipschitz continuous and pseudo-contractive maps.  ...  Under feasibility condition, the algorithm generates an error as d(a t , a * ) ≤ ρ(M w ) t d(a 0 , a * ), which provides the convergence of the algorithm to a * .  ...

Convergence Criteria of Three Step Schemes for Solving Equations

Samundra Regmi, Christopher I. Argyros, Ioannis K. Argyros, Santhosh George
2021 Mathematics  
We develop a unified convergence analysis of three-step iterative schemes for solving nonlinear Banach space valued equations.  ...  So, the usage of them is restricted six or higher differentiable mappings. But in our paper only the first Frèchet derivative is utilized to show convergence. Consequently, the scheme is expanded.  ...  In order to extend the utilization of these schemes, we study the local convergence of scheme (2): in a Banach space, under generalized continuity conditions and using hypotheses only on the operators  ...

2020 Contemporary Mathematics  
There is a plethora of schemes of the same convergence order for generating a sequence approximating a solution of an equation involving Banach space operators.  ...  But the set of convergence criteria is not the same in general.
