چکیده

In this paper we give extensions of the Hoeffding-Azuma inequalities for weighted sums of uniformly bounded martingale differences. Our results improve previous results of Antonov (1979).

Concentration Inequalities

1.1. Azuma-Hoeffding Inequality. Concentration inequalities are inequalities that bound probabilities of deviations by a random variable from its mean or median. Our interest will be in concentration inequalities in which the deviation probabilities decay exponentially or superexponentially in the distance from the mean. One of the most basic such inequality is the Azuma-Hoeffding inequality fo...

On Refined Versions of the Azuma-Hoeffding Inequality with Applications in Information Theory

This chapter introduces some concentration inequalities for discrete-time martingales with bounded increments, and it exemplifies some of their potential applications in information theory and related topics. The first part of this chapter introduces briefly discrete-time martingales and the Azuma-Hoeffding & McDiardmid’s inequalities which are widely used in this context. It then derives these...

User-Friendly Tail Bounds for Sums of Random Matrices

This work presents probability inequalities for sums of independent, random, selfadjoint matrices. The results frame simple, easily verifiable hypotheses on the summands, and they yield strong conclusions about the large-deviation behavior of the maximum eigenvalue of the sum. Tail bounds for the norm of a sum of rectangular matrices follow as an immediate corollary, and similar techniques yiel...

Lecture 4 : Concentration and Matrix Multiplication

Today, we will continue with our discussion of scalar and matrix concentration, with a discussion of the matrix analogues of Markov’s, Chebychev’s, and Chernoff’s Inequalities. Then, we will return to bounding the error for our approximating matrix multiplication algorithm. We will start with using Hoeffding-Azuma bounds from last class to get improved Frobenius norm bounds, and then (next time...

Quelques mots sur l’inégalité de concentration de Azuma-Hoeffding

L’inégalité de concentration de Azuma-Hoeffding fait partie de ces beaux outils mathématiques à la fois simples et utiles. Elle mérite d’être connue par tous ceux qui s’intéressent aux probabilités. Dans cet exposé, on en donne une version due à McDiarmid, ainsi qu’une application aux mesures spectrales empiriques de matrices aléatoires, puis au problème du voyageur de commerce en optimisation ...
