Webb8 okt. 2010 · Remark: By Pinsker’s inequality, $latex K (q,p) \geq 2 (p-q)^2$. Proof Let’s do the $latex q > p$ case; the other is identical. Let $latex \theta_p$ be the distribution over $latex \ {0,1\}^n$ induced by a coin of bias $latex p$, and likewise $latex \theta_q$ for a coin of bias $latex q$.

Webb20 sep. 2015 · Lemma 1 (Pinsker-type inequality) Let be a random variable taking values in a finite range of cardinality , let be a uniformly distributed random variable in , and let be a subset of . Then Proof: Consider the conditional entropy . On the one hand, we have by Jensen’s inequality. On the other hand, one has Webband Vajda [HV11], which gives the sharpest possible comparison inequality between arbitrary f-divergences (and puts an end to a long sequence of results starting from Pinsker’s inequality). This material can be skimmed on the rst reading and referenced later upon need. 7.1 De nition and basic properties of f-divergences De nition 7.1 (f ... WebbA proof of a slightly weaker theorem is presented inAppendix A. 12.2 Lower bound for Disjointness In this section, we will prove the (n) lower bound for the randomized private coins commu-nication complexity of Disjointness, using the above properties of Hellinger distance. Recall that DISJ(x;y) = ^ i x i_y i= ^ i NAND(x i;y i): bitterroot hair studio
