Fast and Asymptotically Powerful Detection for Filamentary Objects in Digital Images
Kai Ni, Shanshan Cao, Xiaoming Huo
Given an inhomogeneous chain embedded in a noisy image, we consider the conditions under which such an embedded chain is detectable. Many applications, such as detecting moving obj…
A Unifying Framework of High-Dimensional Sparse Estimation with Difference-of-Convex (DC) Regularizations
Shanshan Cao, Xiaoming Huo, Jong-Shi Pang
Under the linear regression framework, we study the variable selection problem when the underlying model is assumed to have a small number of nonzero coefficients (i.e., the underl…
When do stepwise algorithms meet subset selection criteria?
Xiaoming Huo, Xuelei, Ni
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 pa…
Adaptive multiscale detection of filamentary structures in a background of uniform random points
Ery Arias-Castro, David L. Donoho, Xiaoming Huo
We are given a set of points that might be uniformly distributed in the unit square . We wish to test whether the set, although mostly consisting of uniformly scattere…
