      Minimax rate distortion for a class of sources 

      Rezaei, F.; Charalambous, Charalambos D.; Stavrou, P. A.; Kourtellaris, C. (2010)
      This paper deals with rate distortion or source coding with fidelity criterion, in measure spaces, for a class of source distributions. The class of source distributions is described by a relative entropy constraint set ...

      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 ...

      Rate distortion function with causal decoding 

      Charalambous, Charalambos D.; Kourtellaris, C. K.; Stavrou, P. A. (2010)
      This paper considers source coding of general sources with memory, when causal feedback is available at the decoder. The rate distortion function is defined as the infimum of the so-called directed information over causal ...
