Chernoff bound dependent variable
WebWe seek to derive a probabilistic tool known as the Cherno Bound, a useful bound on deviation from the expected value of the sum of independent random variables. First, we … WebThe Chernoff bound gives a much tighter control on the proba-bility that a sum of independent random variables deviates from its expectation. Although here we …

WebIn order to address this issue we use the Chernoff-Hoeffding bound. Chernoff-Hoeffding Suppose X1,. . ., Xn are independent random variables taking values in between 0 and 1, and let X = X1 + X2 +. . . + Xn be their sum, and E[X] = m. There are many forms of the Chernoff bounds, but here we focus on this one: There are several other kinds of bounds WebThus, special cases of the Bernstein inequalities are also known as the Chernoff bound, Hoeffding's inequality and Azuma's inequality . Some of the inequalities [ edit] 1. Let be independent zero-mean random variables. Suppose that almost surely, for all Then, for all positive , 2. Let be independent zero-mean random variables.
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).

WebSection 2 we prove that the moment bound is not greater than Chernoff's bound for all distributions provided that t > 0. In Section 3 we compute the moment bound for a number of distributions, both discrete and continuous, and show that the moment bound can be substantially tighter than Chernoff's bound.
