DESCRIPTION:Title: <a href="https://researchseminars.org/talk/Intercats/7/
 ">Bidirectional compositionality in inference and stochastic optimisation<
 /a>\nby Moritz Schauer (Chalmers University and University of Gothenburg) 
 as part of Intercats: Seminar on Categorical Interaction\n\n\nAbstract\nBa
 yesian inference\, entropy-regularised optimal transport and optimal contr
 ol are linked via a variational formalism. The laws of compositionality of
  the formalism are of optical nature: the Bellman principle leads to bidir
 ectional (backward-forward) representation of the posterior\, the optimall
 y controlled process or the optimal transport scheme. The Backward Filteri
 ng Forward Guiding (BFFG) paradigm (Mider et al.\, 2020) is an extension w
 hich incorporates a Monte Carlo element. This allows to formulate a set of
  elementary (and\, by Monte Carlo\, tractable) transformation rules of fun
 ctorial nature suitable for automatisation in probabilistic programming.\n
