Approximate Algorithms for Chamfer Distance Under Translation
arXiv:2605.25280v2 Announce Type: replace Abstract: Given two sets of points A and B, $|A| = m$, $|B| = n$, the Chamfer distance from $A$ to $B$ is defined as $\operatorname{CD}(A,B) = \sum_{a\in A} \min_{b\in B} d(a,b)$, where $d$ is a distance metric. Chamfer distance is a popular measure of dissimilarity between two sets of points that has seen increasing usage in computer vision and information retrieval as a substitute for the more computationally demanding Earth Mover's distance.
Spectral density estimation for normal matrices
Announce Type: new Abstract: The spectral density estimation problem asks for an algorithm that, given an $n\times n$ matrix $A$, outputs a probability measure that is a good approximation to the uniform distribution on the eigenvalues of $A$, called the spectral density of $A$. This paper considers the setting where $A$ is a large normal matrix that is accessible only through matrix-vector product queries. We provide an algorithm that makes just $m$ matrix-vector queries to $A$ and returns,...
AI’s elite celebrated in Washington as the public sours on data centers and chatbots
WASHINGTON — Glitz, glamor and geopolitics were on the menu Wednesday night as Washington’s AI elite gathered to mingle and celebrate AI pioneers. Complete with a red carpet and a dancing humanoid robot, the event could have been mistaken for a science fiction Hollywood premiere. Even as AI becomes an increasing source of tension in communities across America, the night’s honorees were largely optimistic about the trajectory of AI and its potential impact on society.
