The capacity region of a class of broadcast channels with a sequence of less noisy receivers
The capacity region of a broadcast channel consisting of k-receivers that lie in a less noisy sequence is an open problem, when k 3. We prove that superposition coding is indeed ...

Dynamic data polyvariance using source-tagged classes
The DDP (Demand-driven/Pruning) analysis algorithm allows us to perform data-flow analyses of programming languages that are dynamically typed and have higher-order control flow...

Submodular dictionary learning for sparse coding
A greedy-based approach to learn a compact and discriminative dictionary for sparse representation is presented. We propose an objective function consisting of two components: ent...

Universal Coding on Infinite Alphabets: Exponentially Decreasing Envelopes
This paper deals with the problem of universal lossless coding on a countable infinite alphabet. It focuses on some classes of sources defined by an envelope condition on the margi...

Low-Rate Repeat-Zigzag-Hadamard Codes
In this paper, we propose a new class of low-rate error correction codes called repeat-zigzag-Hadamard (RZH) codes featuring simple encoder and decoder structures, and flexible cod...
