Binomial Tails for Community Analysis
Omid Madani, Thanh Ngo, Weifei Zeng +5
An important task of community discovery in networks is assessing significance of the results and robust ranking of the generated candidate groups. Often in practice, numerous cand…
ExplainIt! -- A declarative root-cause analysis engine for time series data (extended version)
Vimalkumar Jeyakumar, Omid Madani, Ali Parandeh +3
We present ExplainIt!, a declarative, unsupervised root-cause analysis engine that uses time series monitoring data from large complex systems such as data centres. ExplainIt! empo…
Alignment based Network Coding for Two-Unicast-Z Networks
Weifei Zeng, Viveck R. Cadambe, Muriel Medard
In this paper, we study the wireline two-unicast-Z communication network over directed acyclic graphs. The two-unicast-Z network is a two-unicast network where the destination inte…
Multi-Path TCP with Network Coding for Mobile Devices in Heterogeneous Networks
Jason Cloud, Flavio du Pin Calmon, Weifei Zeng +3
Existing mobile devices have the capability to use multiple network technologies simultaneously to help increase performance; but they rarely, if at all, effectively use these tech…
Joint Coding and Scheduling Optimization in Wireless Systems with Varying Delay Sensitivities
Weifei Zeng, Chris T. K. Ng, Muriel Medard
Throughput and per-packet delay can present strong trade-offs that are important in the cases of delay sensitive applications.We investigate such trade-offs using a random linear n…
Sparse Network Coding with Overlapping Classes
Danilo Silva, Weifei Zeng, Frank R. Kschischang
This paper presents a novel approach to network coding for distribution of large files. Instead of the usual approach of splitting packets into disjoint classes (also known as gene…
