Finite-state transducers for substitution tilings

Abstract
We present a suite of algorithmic techniques for handling substitution tilings by treating a tile's hierarchy of supertiles in a purely combinatorial fashion using finite state automata. The resulting techniques are very convenient for practical generation of patches of tilings such as hats…

Stochastic Optimization with Random Search

arXiv:2510.15610v2 Announce Type: replace-cross
Abstract: We revisit random search for stochastic optimization, where only noisy function evaluations are available. We show that the method works under weaker smoothness assumptions than previously considered, and that stronger assumptions enable imp…

Asymptotic regularity of a generalised stochastic Halpern scheme

arXiv:2411.04845v3 Announce Type: replace-cross
Abstract: We provide abstract, general and highly uniform rates of asymptotic regularity for a generalized stochastic Halpern-style iteration, which incorporates a second mapping in the style of a Krasnoselskii-Mann iteration. This iteration is genera…

On the Universal Representation Property of Spiking Neural Networks

arXiv:2512.16872v1 Announce Type: new
Abstract: Inspired by biology, spiking neural networks (SNNs) process information via discrete spikes over time, offering an energy-efficient alternative to the classical computing paradigm and classical artificial neural networks (ANNs). In this work, we analy…

Hierarchical Neural Surfaces for 3D Mesh Compression

arXiv:2512.15985v1 Announce Type: new
Abstract: Implicit Neural Representations (INRs) have been demonstrated to achieve state-of-the-art compression of a broad range of modalities such as images, videos, 3D surfaces, and audio. Most studies have focused on building neural counterparts of tradition…

CoVAR: Co-generation of Video and Action for Robotic Manipulation via Multi-Modal Diffusion

arXiv:2512.16023v1 Announce Type: new
Abstract: We present a method to generate video-action pairs that follow text instructions, starting from an initial image observation and the robot's joint states. Our approach automatically provides action labels for video diffusion models, overcoming the com…

Learning Confidence Ellipsoids and Applications to Robust Subspace Recovery

arXiv:2512.16875v1 Announce Type: new
Abstract: We study the problem of finding confidence ellipsoids for an arbitrary distribution in high dimensions. Given samples from a distribution $D$ and a confidence parameter $\alpha$, the goal is to find the smallest volume ellipsoid $E$ which has probabil…

December has the longest days (wherever you live)

The longest days accompany the winter solstice. In December, a day - a whole cycle of day and night - is about half a minute longer than the average 24 hours.
The post December has the longest days (wherever you live) first appeared on EarthSky.

CRISPR Turns a Little-Known Fruit Into a Big Farming Opportunity

Scientists are using CRISPR to fast-track the domestication of a wild fruit. For roughly 10,000 years, farming communities have improved crops by saving seeds from plants that produced better harvests. By repeatedly choosing varieties with desirable traits such as larger size, better flavor, and gre…

OPENTOUCH: Bringing Full-Hand Touch to Real-World Interaction

arXiv:2512.16842v1 Announce Type: new
Abstract: The human hand is our primary interface to the physical world, yet egocentric perception rarely knows when, where, or how forcefully it makes contact. Robust wearable tactile sensors are scarce, and no existing in-the-wild datasets align first-person …
