Interpretations of Directed Information in Portfolio Theory, Data Compression, and Hypothesis Testing
Haim H. Permuter, Young-Han Kim, Tsachy Weissman
We investigate the role of Massey's directed information in portfolio theory, data compression, and statistics with causality constraints. In particular, we show that directed info…
Error Exponents for the Gaussian Channel with Active Noisy Feedback
Young-Han Kim, Amos Lapidoth, Tsachy Weissman
We study the best exponential decay in the blocklength of the probability of error that can be achieved in the transmission of a single bit over the Gaussian channel with an active…
Deterministic Relay Networks with State Information
Sung Hoon Lim, Young-Han Kim, Sae-Young Chung
Motivated by fading channels and erasure channels, the problem of reliable communication over deterministic relay networks is studied, in which relay nodes receive a function of th…
Sparse Linear Representation
Halyun Jeong, Young-Han Kim
This paper studies the question of how well a signal can be reprsented by a sparse linear combination of reference signals from an overcomplete dictionary. When the dictionary size…
Correlated Sources over Broadcast Channels
Paolo Minero, Young-Han Kim
The problem of reliable transmission of correlated sources over the broadcast channel, originally studied by Han and Costa, is revisited. An alternative characterization of their s…
