Compress-and-Forward via Multilevel Coding and Trellis Coded Quantization
Heping Wan, Anders Host-Madsen, Aria Nosratinia
Compress-forward (CF) relays can improve communication rates even when the relay cannot decode the source signal. Efficient implementation of CF is a topic of contemporary interest…
Graph Compression with Application to Model Selection
Mojtaba Abolfazli, Anders Host-Madsen, June Zhang +1
Many multivariate data such as social and biological data exhibit complex dependencies that are best characterized by graphs. Unlike sequential data, graphs are, in general, unorde…
Bounds for Learning Lossless Source Coding
Anders Host-Madsen
This paper asks a basic question: how much training is required to beat a universal source coder? Traditionally, there have been two types of source coders: fixed, optimum coders s…
Coding of Graphs with Application to Graph Anomaly Detection
Anders Host-Madsen, June Zhang
This paper has dual aims. First is to develop practical universal coding methods for unlabeled graphs. Second is to use these for graph anomaly detection. The paper develops two co…
Data Discovery and Anomaly Detection Using Atypicality: Theory
Anders Høst-Madsen, Elyas Sabeti, Chad Walton
A central question in the era of 'big data' is what to do with the enormous amount of information. One possibility is to characterize it through statistics, e.g., averages, or clas…
Repair of Multiple Descriptions on Distributed Storage
Anders Host-Madsen, Heechoel Yang, Minchul Kim +1
In multiple descriptions on distributed storage, a source is stored in a shared fashion on multiple servers. When a subset of servers are contacted, the source should be estimated…
On the Minimum Energy of Sending Gaussian Multiterminal Sources over the Gaussian MAC
Nan Jiang, Yang Yang, Anders Høst-Madsen +1
In this work, we investigate the minimum energy of transmitting correlated sources over the Gaussian multiple-access channel (MAC). Compared to other works on joint source-channel…
The Wideband Slope of Interference Channels: The Small Bandwidth Case
Minqi Shen, Anders Høst-Madsen
This paper studies the low-SNR regime performance of a scalar complex K -user interference channel with Gaussian noise. The finite bandwidth case is considered, where the low-SNR r…
The Wideband Slope of Interference Channels: The Large Bandwidth Case
Minqi Shen, Anders Høst-Madsen
It is well known that minimum received energy per bit in the interference channel is -1.59dB as if there were no interference. Thus, the best way to mitigate interference is to ope…
Deterministic Capacity of MIMO Relay Networks
Anders Host-Madsen
The deterministic capacity of a relay network is the capacity of a network when relays are restricted to transmitting \emph{reliable} information, that is, (asymptotically) determi…
