Statistical Estimation and Clustering of Group-invariant Orientation Parameters
Yu-Hui Chen, Dennis Wei, Gregory Newstadt +3
We treat the problem of estimation of orientation parameters whose values are invariant to transformations from a spherical symmetry group. Previous work has shown that any such gr…
A Dictionary Approach to EBSD Indexing
Yu-Hui Chen, Se Un Park, Dennis Wei +5
We propose a framework for indexing of grain and sub-grain structures in electron backscatter diffraction (EBSD) images of polycrystalline materials. The framework is based on a pr…
On two relaxations of quadratically-constrained cardinality minimization
Dennis Wei
This paper considers a quadratically-constrained cardinality minimization problem with applications to digital filter design, subset selection for linear regression, and portfolio…
Multistage Adaptive Estimation of Sparse Signals
Dennis Wei, Alfred O. Hero
This paper considers sequential adaptive estimation of sparse signals under a constraint on the total sensing effort. The advantage of adaptivity in this context is the ability to…
