A New Approach to Inverting Backscatter and Extinction from Photon-Limited Lidar Observations
Willem J. Marais, Robert E. Holz, Yu Hen Hu +3
Atmospheric lidar observations provide a unique capability to directly observe the vertical column of cloud and aerosol scattering properties. Detector and solar background noise,…
Regularized Non-Gaussian Image Denoising
Albert Oh, Rebecca Willett
In image denoising problems, one widely-adopted approach is to minimize a regularized data-fit objective function, where the data-fit term is derived from a physical image acquisit…
Reducing Basis Mismatch in Harmonic Signal Recovery via Alternating Convex Search
Jonathan M. Nichols, Albert K. Oh, Rebecca M. Willett
The theory behind compressive sampling pre-supposes that a given sequence of observations may be exactly represented by a linear combination of a small number of basis vectors. In…
Online Markov decision processes with Kullback-Leibler control cost
Peng Guan, Maxim Raginsky, Rebecca Willett
This paper considers an online (real-time) control problem that involves an agent performing a discrete-time random walk over a finite state space. The agent's action at each time…
This is SPIRAL-TAP: Sparse Poisson Intensity Reconstruction ALgorithms - Theory and Practice
Zachary T. Harmany, Roummel F. Marcia, Rebecca M. Willett
The observations in many applications consist of counts of discrete events, such as photons hitting a detector, which cannot be effectively modeled using an additive bounded or Gau…
Sparse Poisson Intensity Reconstruction Algorithms
Zachary T. Harmany, Roummel F. Marcia, Rebecca M. Willett
The observations in many applications consist of counts of discrete events, such as photons hitting a dector, which cannot be effectively modeled using an additive bounded or Gauss…
