Appendix C: Topics in Probability -- Bibliography -- Index. .This book serves as an advanced text for a graduate course on stochastic algorithms for the students of probability and statistics, engineering, economics and machine learning. This second edition gives a comprehensive treatment of stochastic approximation algorithms based on the ordinary differential equation (ODE) approach which analyses the algorithm in terms of a limiting ODE. It has a streamlined treatment of the classical convergence analysis and includes several recent developments such as concentration bounds, avoidance of traps, stability tests, distributed and asynchronous schemes, multiple time scales, general noise models, etc., and a category-wise exposition of many important applications. It is also a useful reference for researchers and practitioners in the field.Texts and Readings in Mathematics,2366-8725 ;48StatisticsArtificial intelligenceProbabilitiesOperations researchGame theoryAutomatic controlStatistical Theory and MethodsArtificial IntelligenceProbability TheoryOperations Research and Decision TheoryGame TheoryControl and Systems TheoryAnàlisi estocàsticathubLlibres electrònicsthubStatistics.Artificial intelligence.Probabilities.Operations research.Game theory.Automatic control.Statistical Theory and Methods.Artificial Intelligence.Probability Theory.Operations Research and Decision Theory.Game Theory.Control and Systems Theory.Anàlisi estocàstica519.2Borkar Vivek S.472615MiAaPQMiAaPQMiAaPQBOOK9910831015103321Stochastic approximation225441UNINA
