Worst-Case Source for Distributed Compression with Quadratic Distortion
Ilan Shomorony, A. Salman Avestimehr, Himanshu Asnani +1
We consider the k-encoder source coding problem with a quadratic distortion measure. We show that among all source distributions with a given covariance matrix K, the jointly Gauss…
The Porosity of Additive Noise Sequences
Vinith Misra, Tsachy Weissman
Consider a binary additive noise channel with noiseless feedback. When the noise is a stationary and ergodic process , the capacity is ($\mat…
Compression with Actions
Lei Zhao, Yeow-Khiang Chia, Tsachy Weissman
We consider the setting where actions can be used to modify a state sequence before compression. The minimum rate needed to losslessly describe the optimal modified sequence is cha…
Reference Based Genome Compression
Bobbie Chern, Idoia Ochoa, Alexandros Manolakos +3
DNA sequencing technology has advanced to a point where storage is becoming the central bottleneck in the acquisition and mining of more data. Large amounts of data are vital for g…
Successive Refinement with Decoder Cooperation and its Channel Coding Duals
Himanshu Asnani, Haim Permuter, Tsachy Weissman
We study cooperation in multi terminal source coding models involving successive refinement. Specifically, we study the case of a single encoder and two decoders, where the encoder…
Estimation with a helper who knows the interference
Yeow-Khiang Chia, Rajiv Soundararajan, Tsachy Weissman
We consider the problem of estimating a signal corrupted by independent interference with the assistance of a cost-constrained helper who knows the interference causally or noncaus…
Universal Estimation of Directed Information
Jiantao Jiao, Haim H. Permuter, Lei Zhao +2
Four estimators of the directed information rate between a pair of jointly stationary ergodic finite-alphabet processes are proposed, based on universal probability assignments. Th…
