Expected time averages in Markovian imprecise jump processes : a graph-theoretic characterisation of weak ergodicity Ghent University
Markovian imprecise jump processes provide a way to express model uncertainty about Markovian jump processes. The dynamics are not governed by a unique rate matrix, but are instead partially specified by a set of such matrices. Since the dynamics are partially specified, the resulting expected time averages are no longer uniquely determined either, and one then resorts to tight lower and upper bounds on them. In this paper, we are interested in ...
Coherent and Archimedean choice in general Banach spaces Ghent University
Randomness is inherently imprecise Ghent University
On a notion of independence proposed by Teddy Seidenfeld Ghent University
Teddy Seidenfeld has been arguing for quite a long time that binary preference models are not powerful enough to deal with a number of crucial aspects of imprecision and indeterminacy in uncertain inference and decision making. It is at his insistence that we initiated our study of so-called sets of desirable option sets, which we have argued elsewhere provides an elegant and powerful approach to dealing with general, binary as well as ...
Imprecise discrete-time Markov chains Ghent University
I present a short and easy introduction to a number of basic definitions and important results from the theory of imprecise Markov chains in discrete time, with a finite state space. The approach is intuitive and graphical.
