Directed Information on Abstract Spaces: Properties and Variational Equalities
(2016)Directed information or its variants are utilized extensively in the characterization of the capacity of channels with memory and feedback, nonanticipative lossy data compression, and their generalizations to networks. In ...

Information Structures for Feedback Capacity of Channels with Memory and Transmission Cost: Stochastic Optimal Control & Variational Equalities
(2017)The Finite Transmission Feedback Information (FTFI) capacity is characterized for any class of channel conditional distributions PBi|Bi-1, Ai and P Bi|Bi-1 i-M, Ai, where M is the memory of the channel, Bi ? {B-1, B0,..., ...

Information structures of capacity achieving distribution for channels with memory and feedback
(Institute of Electrical and Electronics Engineers Inc., 2016)The information structures of the optimal channel input distributions P[0,n] t {PAi|Ai-1,Bi-1 : i = 0,1.,n}, which correspond to the extremum problem of feedback capacity equation are identified, for any class of channel ...

Variational equalities of directed information and applications
(2013)In this paper we introduce two variational equalities of directed information, which are analogous to those of mutual information employed in the Blahut-Arimoto Algorithm (BAA). Subsequently, we introduce nonanticipative ...
