Predictive Volatility of Machine Learning in Micro-Samples: A Regularised Assessment of Regional Poverty
arXiv:2604.06278v4 Announce Type: replace-cross Abstract: Small regional datasets pose a dual statistical problem: correlated predictors inflate estimation variance, while flexible learners can become unstable because the available information per adaptive degree of freedom is limited. We examine this issue through predictive volatility, defined as the cross-sample dispersion and upper-tail behaviour of out-of-sample loss. Using simulation evidence reported for sparse linear, near-linear and...

New light-powered chip could accelerate AI and quantum computing
New light-powered chip could accelerate AI and quantum computing - Date: - June 2, 2026 - Source: - Monash University - Summary: - Scientists have created a tiny chip that can generate, steer, and read light-based information all in one device, marking a major leap toward ultra-fast, energy-efficient computing. The breakthrough uses atomically thin materials and nanoscale structures to control a unique quantum property of light called the “valley” degree of freedom, allowing information to...
At least 1.5 million people taken to court over unpaid council tax
At least 1.5 million people taken to court over unpaid council tax GMB national secretary said the ‘horrifying figures show our council tax system is completely broken’ - Bookmark - CommentsGo to comments New research suggests that at least 1.5 million people were taken to court over unpaid council tax debt last year. The GMB revealed freedom of information replies from 200 local authorities across Britain showed that 1.4 million people had been summoned to court in the financial year...
HMRC '£3,000 penalties' in inheritance tax crackdown
HMRC '£3,000 penalties' in inheritance tax crackdown Penalties can rise to £3,000 An HMRC inheritance tax crackdown has seen inheritance tax, or IHT, penalties surge by a third. Grieving families have been compelled to hand over £3m in fines to HMRC and the Labour Party government's tax arm. HMRC has slapped the executors of 5,200 estates with late-filing penalties totalling £3.1m in 2024-25, averaging £596 each, according to data obtained under Freedom of Information rules.
Effective Dimensionality as an Operator Invariant for Physics-Preserving Constraint Adaptation in Physics-Informed Neural Networks
Announce Type: cross Abstract: Physics-Informed Neural Networks inherently suffer from task interference because they rely on a shared parameter space to satisfy both governing differential equations and boundary conditions. We analyze this structural conflict using the Fisher Information Matrix to quantify the effective degrees of freedom ($d_{eff}$) in a physics-constrained model. Unlike the classical $d_{eff}$ which measures how many parameter directions are informed by data against a...

The Pirate Bay Remains Resilient, 20 Years After the Raid
There are a handful of traditions we have at TorrentFreak, and remembering the first raid on The Pirate Bay is one of them. It was not only the first major story we covered, it also shaped how the piracy ecosystem evolved over the years. And it changed the lives of the site’s co-founders, who were eventually convicted.
