    Optimality conditions for maximizers of the information divergence from an exponential family

  • Original language description

    The information divergence of a probability measure P from an exponential family E over a finite set is defined as infimum of the divergences of P from Q over Q in E. All directional derivatives of the divergence from E are explicitly found. To this end,behaviour of the conjugate of a log-Laplace transform on the boundary of its domain is analysed. The first order conditions for P to be a maximizer of the divergence from E are presented, including new ones when P is not projectable to E.

    Podmínky oprimality pro informační divergenci od exponenciální rodiny

  • Czech description

    Informační divergence pravděpodobnostní měry P od exponenciální rodiny E se definuje jako infimum informačních divergencí P od Q cez Q v E. Pro diskrétní E byly explicitně nalezeny všechny směrové derivace informační divergence of E. Za tím účelem bylo studováno chování konjugované funkce k log-Laplacově transformaci. Byly nalezeny všechny podmínky optimality prvního řádu.
