Web• Jensen-Shannon divergence: f(x) = xlog 2x x+1 + log 2 x+1, JS(P;Q) = D P P+ Q 2 + D Q P+ Q 2 : Moreover, p JS(PkQ) is a metric on the space of probability distributions [ES03]. Remark 7.3. If D f(PkQ) is an f-divergence, then it is easy to verify that D f( P+ Q kQ) and D f(Pk P+ Q ) are f-divergences for all 2[0;1]. In particular, D f(QkP ...
