Functional Multi-Reference Alignment via Deconvolution
This paper studies the multi-reference alignment (MRA) problem of estimating a signal function from shifted, noisy observations. Our functional formulation reveals a new connection between MRA and deconvolution: the signal can be estimated from second-order statistics via Kotlarski's formula, an important identification result in deconvolution with replicated measurements. To design our MRA algorithms, we extend Kotlarski's formula to general dimension and study the estimation of signals with v…

It’s especially frustrating because there •is• election manipulation happening in plain sight: voter suppression, gerrymandering, a vast media empire of right-wing falsehood, microtargeted disinformation from billionaires and hostile foreign states alike, GOP- and Putin-backed grifters posing as left-leaning third party candidates and then just pocketing the donations and disappearing —
•none• of that even in doubt. We do not need to search for a shadowy conspiracy. Democracy’s being strangled in broad daylight.

Spectral Estimation with Free Decompression
Computing eigenvalues of very large matrices is a critical task in many machine learning applications, including the evaluation of log-determinants, the trace of matrix functions, and other important metrics. As datasets continue to grow in scale, the corresponding covariance and kernel matrices become increasingly large, often reaching magnitudes that make their direct formation impractical or impossible. Existing techniques typically rely on matrix-vector products, which can provide efficient…

“Using this tragedy to push your own political agenda is disgraceful, people are dead,” Democratic activist Nina Turner replied on X.
“Even for MikeLee, this is beyond disgusting,” political scientist Norman Ornstein wrote on X. “Disinformation, beneath contempt.”
“What the hell is Mike Lee doing? Has he completely lost it?” conservative journalist Brad Polumbo also wrote on X.

Decomposition method and upper bound density related to congruent saturated hyperball packings in hyperbolic $n-$space
In this paper, we study the problem of hyperball (hypersphere) packings in $n$-dimensional hyperbolic space ($n \ge 4$). We prove that to each $n$-dimensional congruent saturated hyperball packing, there is an algorithm to obtain a decomposition of $n$-dimensional hyperbolic space $\mathbb{H}^n$ into truncated simplices. We prove, using the above method and the results of the paper \cite{M94}, that the upper bound of the density for saturated congruent hyperball packings, related to the corresp…
