Efficient Unbiased Sparsification

Leighton Barnes, Stephen Cameron, Timothy Chow +6

An unbiased $m$ -sparsification of a vector $p \in R^{n}$ is a random vector $Q \in R^{n}$ with mean $p$ that has at most $m < n$ nonzero coordinates. Unbiased sparsificat…

Multivariate Priors and the Linearity of Optimal Bayesian Estimators under Gaussian Noise

Leighton P. Barnes, Alex Dytso, Jingbo Liu +1

Consider the task of estimating a random vector $X$ from noisy observations $Y = X + Z$ , where $Z$ is a standard normal vector, under the $L^{p}$ fidelity criterion. This work establ…
