The minimum of all such exponential bounds forms the Chernoff or Chernoff-Cramér bound, which may decay faster than … See more The generic Chernoff bound for a random variable $${\displaystyle X}$$ is attained by applying Markov's inequality to $${\displaystyle e^{tX}}$$ (which is why it sometimes called the exponential Markov or exponential … See more Chernoff bounds may also be applied to general sums of independent, bounded random variables, regardless of their distribution; this is known as Hoeffding's inequality. … See more Rudolf Ahlswede and Andreas Winter introduced a Chernoff bound for matrix-valued random variables. The following version of the inequality can be found in the work of Tropp. Let M1, ..., Mt be independent matrix valued random … See more When X is the sum of n independent random variables X1, ..., Xn, the moment generating function of X is the product of the individual moment generating functions, giving that: and: See more The bounds in the following sections for Bernoulli random variables are derived by using that, for a Bernoulli random variable See more Chernoff bounds have very useful applications in set balancing and packet routing in sparse networks. The set balancing … See more The following variant of Chernoff's bound can be used to bound the probability that a majority in a population will become a minority in a sample, or vice versa.

WebChernoff Bounds: Since Chernoff bounds are valid for all values of s > 0 and s < 0, we can choose s in a way to obtain the best bound, that is we can write P ( X ≥ a) ≤ min s > 0 e − s a M X ( s), P ( X ≤ a) ≤ min s < 0 e − s a M X ( s). Let us look at an example to see how we can use Chernoff bounds. Example Let X ∼ B i n o m i a l ( n, p).
