WebIn this paper, we consider mixed divergences that allow one to handle in a unified way the arithmetic symmetrization S (p, q) = 1 2 (D (p: q) + D (q: p)) of a given divergence D (p: q) with both the sided divergences: D (p: q) and its mirror divergence D ′(p: q). The mixed α-divergence is the mixed divergence obtained for the α-divergence. WebEnter the email address you signed up with and we'll email you a reset link.
