BA-T: An Iterative Transformer for Two-View Bundle Adjustment
arXiv:2606.03287v1 Announce Type: new Abstract: Feed-forward models for 3D reconstruction have achieved strong performance using deep cross-view attention to exchange information across images. However, these approaches often depend on heavy decoder stacks and lack a structured mechanism for geometry refinement, resulting in poor multi-view consistency. We address this by drawing inspiration from classical bundle adjustment (BA), which can be viewed as an iterative information propagation...

Secrets of BA's history from paper dresses and grouse for dinner to contraband EXCLUSIVE: A new book charts the extraordinary history of British Airways, inclduing its unusual first passenger flight, its unique link to Marmite, royal fans, and some questionable fashion British Airways has been flying for 107 years, connecting Britain to the world across more than a century of aviation history. From a single biplane lifting off from a grass field in west London to a fleet serving destinations...
BA boss warns costly aviation taxes and rail tickets are stunting UK growth
UK lagging behind rivals on tourism growth because of travel costs and lack of joined-up planning, says CEO Sean DoyleThe cost of travel to and around the UK is keeping millions of tourists away and slowing economic growth, the boss of British Airways said, as he urged a rethink of aviation taxes. The airline’s chief executive, Sean Doyle, said the UK had some of the highest aviation taxes in the world and was falling behind countries such as Japan, France and Germany in boosting its inbound...

Unified light heavyweight champion Dmitry Bivol defeated Michael Eifert by unanimous decision on May 30 in Ekaterinburg, Russia, in his first fight after a 15-month layoff following back surgery. Bivol had last fought in February 2025, when he avenged his loss to Artur Beterbiev with a majority decision victory to unify all four major belts and become the undisputed champion at 175 pounds. Two months later, Bivol relinquished the WBC title to pursue a trilogy bout with Beterbiev rather than...

General Convex Agreement with Near-Optimal Communication
arXiv:2602.21411v2 Announce Type: replace Abstract: Byzantine Agreement (BA) considers a setting of $n$ parties out of which up to $t$ can be byzantine (malicious), and requires the honest parties to agree on an input subject to a condition called \emph{validity}: if all honest parties have input $v$, the output agreed upon must be $v$. Convex Agreement (CA) strengthens BA by requiring the output agreed upon to lie in the convex hull of the honest parties' inputs. This validity condition...
Relaxation Kernel, Spectral Dissipation, and Global Convergence of Blahut--Arimoto Dynamics
arXiv:2604.25106v3 Announce Type: replace Abstract: We develop a spectral theory for continuous- and discrete-time Blahut--Arimoto (BA) dynamics, centered on the relaxation kernel $ \G = \E_p[K^*_X \otimes K^*_X] $. Five main results are established. Along the continuous-time BA flow, the free energy satisfies the exact $ \chi^2 $-dissipation identity $ \dot F_\beta = -\D(q) $, where $ \D(q)=\chi^2(\T q \| q) $ is the Pearson $ \chi^2 $-divergence.
Quantifying Noise of Dynamic Vision Sensor
Announce Type: replace Abstract: Dynamic visual sensors (DVS) are characterized by a large amount of background activity (BA) noise, which it is mixed with the original (cleaned) sensor signal. The dynamic nature of the signal and the absence in practical application of the ground truth, it clearly makes difficult to distinguish between noise and the cleaned sensor signals using standard image processing techniques. In this letter, a new technique is presented to characterise BA noise...
