A Fully Polynomial Approximation Scheme for Approximating a Sum of Random Variables
Threshold probability Tail probability Approximate counting Counting knapsack FPTAS
2016/1/22
Given n independent integer-valued random variables X 1 , X 2 ,..., X n and an integer C, we study the fundamental problem of computing the probability that the sum X = X 1 + X 2 +···+ X n is at most ...
TRACTABLE AND CONSISTENT RANDOM GRAPH MODELS
Random Networks Random Graphs Exponential Random Graph Models

addressing the problem that standard techniques of estimating ERGMs have
been shown to have exponentially slow mixing times for many specifications, we show
that by reformulating network forma...
Near Optimal Signal Recovery From Random Projections:Universal Encoding Strategies?
Random matrices singular values of random matrices signal recovery random projections concentration of measure sparsity trigonometric expansions uncertainty principle convex optimization duality in optimization linear programming
2015/6/17
Suppose we are given a vector f in a class F ⊂ RN, e.g. a class of digital signals or digital images. How many linear measurements do we need to make about f to be able to recover f to within pr...
Can we recover a signal f ∈ RN from a small number of linear measurements? A series of recent papers developed a collection of results showing that it is surprisingly possible to reconstruct certain t...
We analyze the asymptotic behavior of the degree sequence of Random Apollonian Networks.For previous weaker results see.
A radical new approach to the design of communications networks, called “network coding,” promises to make Internet file sharing faster, streaming video more reliable, and cell-phone reception better ...
Control of Spatially Interconnected Systems with Random Communication Losses
Spatially interconnected systems communication losses Markovian jump linear systems
2009/9/9
This paper deals with analysis and synthesis problems of spatially interconnected systems where communicated information may be lost between subsystems. The spatial shift operator as well as the tempo...
A High-Throughput Random Access Protocol for Multiuser MIMO Systems
High-Throughput Random Access Protocol Multiuser MIMO Systems
2009/9/4
We propose a high-throughput random access protocol for 2×2 multiuser multiple-input multiple-output (MIMO) systems. The cross-layer mechanism utilizes the packets combining technique to exploit the a...

Repeated measures Random effects Convergence system Strong convergence Strong convergence rate
2007/12/11
In this article the following random intercept mixed effects model will be considered: $\ y_{ij}=v_{i}+ x_{ij}^{\tau}\beta+\epsilon_{ij}, i=1,\ldots,m;j=1,2,\ldots, n_{i},$ where $\{v_{i}\}$ are i.i.d...
Multi-view Video Coding with Flexible View-Temporal Prediction Structure for Fast Random Access
Multi-view video coding random access
2006/12/31
Multi-view video is becoming increasingly popular, as it provides users greatly enhanced viewing experience. Multi-view video coding (MVC)focuses on exploiting not only the temporal correlation among ...
