      Approximation of Markov Processes by Lower Dimensional Processes via Total Variation Metrics 

      Tzortzis, I.; Charalambous, Charalambos D.; Charalambous, T.; Hadjicostis, Christoforos N.; Johansson, M. (2017)
      The aim of this paper is to approximate a Finite-State Markov (FSM) process by another process defined on a lower dimensional state space, called the approximating process, with respect to a total variation distance fidelity ...

      On the fixed point problem in the abstract rate distortion theory 

      Rezaei, F.; Ahmed, N. U.; Charalambous, Charalambos D. (University of Illinois at Urbana-Champaign, Coordinated Science Laboratory and Department of Computer and Electrical Engineering, 2006)
      This paper introduces a general framework for dealing with the subject of rate distortion or source coding with fidelity criterion, in Polish spaces. The problem is ad-dressed using a variational approach on the space of ...
