When do stepwise algorithms meet subset selection criteria? (2007)
Recent results in homotopy and solution paths demonstrate that certain well-designed greedy algorithms, with a range of values of the algorithmic parameter, can provide solution paths to a sequence...

We are given a set of $n$ points that might be uniformly distributed in the unit square $[0,1]^2$. We wish to test whether the set, although mostly consisting of uniformly scattered points, also...

Connect the dots: how many random points can a regular curve pass through? (2005)
Arias-Castro, Ery, Donoho, David L., Huo, Xiaoming, Tovey, Craig A.
Given a class Γ of curves in [0, 1]2, we ask: in a cloud of n uniform random points, how many points can lie on some curve γ ∈ Γ? Classes studied here include curves of length less than or equal...

Local Linear Projection (llp) (2002)
Dimensionality reduction has important applications in exploratory data analysis. A method based on Local Linear Projection (LLP) is proposed. The advantage of this method is that it is robust...
Some Examples of Untraditional Statistical Computing (2001)
In many cases, finding a maximum likelihood estimator or a Generalized Likelihood Ratio Test estimate becomes an optimization problem. The challenges come when the problem is not formulated as what...
Many problems in data mining, detection, and clustering can be formulated as finding a consecutive subsequence that optimizes an objective function, which is defined for subsequences. Some examples...
An Extreme Value Theorem on the Standardized Increments of Partial Sums (2001)
For an independently and identically distributed Gaussian sequence, X 1 , X 2 , . . . , X n , we consider the maximum of its standardized increments of partial sums (denoted by M I n ). We show that...
Beamlets are a special dyadically organized collection of line segments, exhibiting a range of lengths, positions and orientations. This collection is relatively compact: there are O(n 2 log 2 (n))...

WaveLab is a library of Matlab routines for wavelet analysis, wavelet-packet analysis, cosine-packet analysis and matching pursuit. The library is available free of charge over the Internet. Versions...
Experiments with Combined Image Transforms and Its Implications for Biomedical Image Analysis (2000)
In biomedical images, we observe a variety of features at different frequency bands having different perceptional effects. We analyze how to utilize existing image representations to separate and...
Uncertainty Principles and Ideal Atomic Decomposition (1999)
Suppose a discrete-time signal S(t), 0 t ! N , is a superposition of atoms taken from a combined time/frequency dictionary made of spike sequences 1 ft=g and sinusoids expf2iwt=N)= p N . Can one...
A Simple And Robust Modulation Classification Method Via Counting (1999)
Automatic modulation classification (or recognition) is an intrinsically interesting problem with a variety of regulatory and military applications. We developed a method which is simple, fast,...
Stochastic Behavior Of Inter-Drop Time In An (1999)
Xiaoming Huo, Sam Liu, Hewlett Packard Lab
We studied the stochastic behavior of inter-drop time in an M frame buffer scheme. The problem arises from digital television signal decoding. We can set up a random walk model with lower bound. The...

Stochastic Behavior Of Inter-Drop Time In An M Frame Buffer Video Decoding Scenario (1998)
We studied the stochastic behavior of inter-drop time in an M frame buffer scheme. The problem arises from digital television signal decoding. We can set up a random walk model with lower bound. The...

Time-dependent analysis and application of high-performance concrete in bridges (1997)
High performance concrete (HPC) is now gaining popularity for use in building bridges. The features of HPC include low water-cementitious material ratio, high strength, low permeability, and improved...
