網頁APPLICATIONS OF CHERNOFF BOUNDS 5 Hence, the ideal choice of tfor our bound is ln(1 + ). Substituting this value into our expression, we nd that Pr(X (1 + ) ) (e (1+ )(1+ )) This bound is quite cumbersome to use, so it is useful to provide a slightly less unwieldy 網頁For the function Q ( x) := P ( Z > x) where Z ∼ N ( 0, 1) Q ( x) = ∫ x ∞ 1 2 π exp ( − u 2 2) d u, for x ≥ 0 the following bound is given in many communication systems textbooks: Q ( x) ≤ 1 2 exp ( − x 2 2). The bound without the 1 2 in front of the exponential can be proven directly by Chernoff bound on the Gaussian distribution. highland park dallas homes https://bloomspa.net
