Information Constrained Optimal Transport: From Talagrand, to Marton, to Cover
Yikun Bai, Xiugang Wu, Ayfer Ozgur
The optimal transport problem studies how to transport one measure to another in the most cost-effective way and has wide range of applications from economics to machine learning.…
Minimax Learning for Remote Prediction
Cheuk Ting Li, Xiugang Wu, Ayfer Ozgur +1
The classical problem of supervised learning is to infer an accurate predictor of a target variable from a measured variable by using a finite number of labeled training sa…
"The Capacity of the Relay Channel": Solution to Cover's Problem in the Gaussian Case
Xiugang Wu, Leighton Pate Barnes, Ayfer Ozgur
Consider a memoryless relay channel, where the relay is connected to the destination with an isolated bit pipe of capacity . Let denote the capacity of this channel a…
Cut-Set Bound Is Loose for Gaussian Relay Networks
Xiugang Wu, Ayfer Ozgur
The cut-set bound developed by Cover and El Gamal in 1979 has since remained the best known upper bound on the capacity of the Gaussian relay channel. We develop a new upper bound…

Xiugang Wu, Ayfer Ozgur
The cut-set bound developed by Cover and El Gamal in 1979 has since remained the best known upper bound on the capacity of the Gaussian relay channel. We develop a new upper bound…
A Unified Relay Framework with both D-F and C-F Relay Nodes
Xiugang Wu, Liang-Liang Xie
Decode-and-forward (D-F) and compress-and-forward (C-F) are two fundamentally different relay strategies proposed by (Cover and El Gamal, 1979). Individually, either of them has be…
On the Optimal Compressions in the Compress-and-Forward Relay Schemes
Xiugang Wu, Liang-Liang Xie
..... joint decoding provides more freedom in choosing the compression at the relay. However, the question remains whether this freedom of selecting the compression necessarily imp…
Asymptotic Equipartition Property of Output when Rate is above Capacity
Xiugang Wu, Liang-Liang Xie
The output distribution, when rate is above capacity, is investigated. It is shown that there is an asymptotic equipartition property (AEP) of the typical output sequences, indepen…
