Fano's inequality proof

WebFano’s inequality: a Bernoulli reduction is followed by careful lower bounds on the f{divergences between two Bernoulli distributions. In particular, we are able to extend Fano’s inequality to both continuously many distributions P and arbitrary events A that do not necessarily form a partition or to arbitrary [0;1]{valued random variables Z WebFANO’S INEQUALITY: A TWO-STEP PROOF THEOREM: Let be discrete random variables. Define . Then: . (proof shown in class). Corollary (Fano’s Inequality): Let be …

WebThen, Fano’s inequality tells us that H(E)+plogk≥ H(X Y) H ( E) + p log k ≥ H ( X Y) where H(X Y) H ( X Y) is the conditional entropy of X X given Y Y. This in turn implies a weaker result, namely p≥ H(X Y)−1 logk p ≥ H ( X Y) − 1 log k since the entropy of the binary event E E is at most 1. WebIf we change our equation into the form: ax²+bx = y-c. Then we can factor out an x: x (ax+b) = y-c. Since y-c only shifts the parabola up or down, it's unimportant for finding the x-value of the vertex. Because of this, I'll simply replace it with 0: x …
