Estimation in high-dimensional linear regression: Post-Double-Autometrics as an alternative to Post-Double-Lasso
Hué, Sullivan, Laurent, Sébastien, Aiounou, Ulrich, Flachaire, Emmanuel
Post-Double-Lasso is becoming the most popular method for estimating linear regression models with many covariates when the purpose is to obtain an accurate estimate of a parameter of interest, such as an average treatment effect. However, this method can suffer from substantial omitted variable bias in finite sample. We propose a new method called Post-Double-Autometrics, which is based on Autometrics, and show that this method outperforms Post-Double-Lasso.
A Taxonomy of Pix Fraud in Brazil: Attack Methodologies, AI-Driven Amplification, and Defensive Strategies
Pizzolato, Glener Lanes, Lopes, Brenda Medeiros, Schepke, Claudio, Kreutz, Diego
This work presents a review of attack methodologies targeting Pix, the instant payment system launched by the Central Bank of Brazil in 2020. The study aims to identify and classify the main types of fraud affecting users and financial institutions, highlighting the evolution and increasing sophistication of these techniques. The methodology combines a structured literature review with exploratory interviews conducted with professionals from the banking sector. The results show that fraud schemes have evolved from purely social engineering approaches to hybrid strategies that integrate human manipulation with technical exploitation. The study concludes that security measures must advance at the same pace as the growing complexity of attack methodologies, with particular emphasis on adaptive defenses and continuous user awareness.
Paraconsistent-Lib: an intuitive PAL2v algorithm Python Library
Junior, Arnaldo de Carvalho, da Cruz, Diego Oliveira, Alves, Bruno da Silva, Junior, Fernando da Silva Paulo, Filho, João Inacio da Silva
Abstract: This paper introduces Paraconsistent-Lib, an open-source, easy-to-use Python library for building P AL2v algorithms in reasoning and decision-making systems. Paraconsistent-Lib is designed as a general-purpose library of P AL2v standard calculations, presenting three types of results: paraconsistent analysis in one of the 12 classical lattice P AL2v regions, paraconsistent analysis node (P AN) outputs, and a decision output. With Paraconsistent-Lib, well-known P AL2v algorithms such as Para-analyzer, ParaExtrCTX, P AL2v Filter, paraconsistent analysis network (P ANnet), and paraconsistent neural network (PNN) can be written in stand-alone or network form, reducing complexity, code size, and bugs, as two examples presented in this paper. Given its stable state, Paraconsistent-Lib is an active development to respond to user-required features and enhancements received on GitHub.Keywords: Paraconsistent-Lib, P AL2v, Python Library, Reasoning, Decision-Making1. IntroductionThe desire to create an automaton capable of imitating human behavior is long-standing.
In Defense of the Turing Test and its Legacy
Considering that Turing's original test was co-opted by Weizenbaum and that six of the most common criticisms of the Turing test are unfair to both Turing's argument and the historical development of AI. The Turing test has faced criticism for decades, most recently at the Royal Society event "Celebrating the 75th Anniversary of the Turing Test." The question of the Turing test's significance has intensified with recent advances in large language model technology, which now enable machines to pass it. In this article, I address six of the most common criticisms of the Turing test: The Turing test encourages fooling people; Turing overestimated human intelligence, as people can be easily fooled (the ELIZA effect); The Turing test is not a good benchmark for AI; Turing's 1950 paper is not serious and/or has contradictions; Imitation should not be a goal for AI, and it is also harmful to society; Passing the Turing test teaches nothing about AI. All six criticisms largely derive from Joseph Weizenbaum's influential reinterpretation of the Turing test. The first four fail to withstand a close examination of the internal logic of Turing's 1950 paper, particularly when the paper is situated within its mid-twentieth-century context.
Russia says talks to end Ukraine war 'serious' but rules out concessions
What is in the 28-point US plan for Ukraine? Why is Europe opposing Trump's peace plan? Is the fall of Pokrovsk inevitable? 'A corruption scandal may well end the Ukraine war' Russia says talks to end Ukraine war'serious' but rules out concessions Russia says the United States-brokered talks to end the war with Ukraine are "serious", but its officials caution that an agreement is a long way off and Moscow would offer no major concessions to Kyiv. Kremlin spokesman Dmitry Peskov said in televised comments on Wednesday that the negotiations were ongoing and "the process is serious."
Jeff Bezos' New AI Venture Quietly Acquired an Agentic Computing Startup
Jeff Bezos' New AI Venture Quietly Acquired an Agentic Computing Startup Project Prometheus has raised over $6 billion in funding and hired over 100 employees, a handful of whom joined through its acquisition of General Agents, according to records and sources. In early June, tech entrepreneur Vik Bajaj took over Saison, a two-Michelin star restaurant in San Francisco, for an off-the-record dinner to talk about AI with journalists and a handful of scientists. In attendance was Sherjil Ozair, a late addition who had previously held senior research roles at DeepMind and Tesla . The following day, Bajaj and Ozair were on their way to making a deal, public records show. Bajaj didn't mention it at the dinner, but earlier this year he had begun working with Amazon executive chairman Jeff Bezos on a new AI venture called Project Prometheus.
Australia's beloved weather website got a makeover - and infuriated users
Australia's beloved weather website got a makeover - and infuriated users It was an unseasonably warm spring day in Sydney on 22 October, with a forecast of 39C (99F) - a real scorcher. The day before, the state of New South Wales had reported its hottest day in over a century, a high of 44.8C in the outback town of Bourke. But little did the team at the national Bureau of Meteorology foresee that they, in particular, would soon be feeling the heat. Affectionately known by Australians as the Bom, the agency's long-awaited website redesign went live that morning, more than a decade after the last update. Within hours, the Bom was flooded with a deluge of complaints.
Nvidia plays down Google chip threat concerns
Nvidia has claimed it is a generation ahead of rivals in the artificial intelligence (AI) industry amid growing suggestions a rival may emerge to threaten to its market dominance - and multi-trillion dollar valuation. Shares in the chip giant fell on Tuesday, following a report Meta planned to spend billions on AI chips developed by Google to power its data centres. In a statement on X, Nvidia, the world's most valuable company, said it was the only platform which runs every AI model and does it everywhere computing is done. In response, Google said it was committed to supporting both its own and Nvidia's chips. Nvidia's chips have become a critical part of powering the data centres behind many of the most popular AI tools, such as ChatGPT.

'Hidden' volcanoes pose the greatest risk to the world, scientists warn - after little-known mount erupts in Ethiopia READ MORE: Scientists discover a new hole in one of Yellowstone's basins A little-known Ethiopian volcano has erupted for the first time in at least 12,000 years - sparking fears that'hidden' volcanoes are being missed. Professor Mike Cassidy, a volcanologist at the University of Birmingham, says the world's overlooked volcanoes'pose the greatest threat'. Known as'hidden' volcanoes, they're less famous than Yellowstone or Etna even among scientists - which means they're not being monitored as much. Examples include El Chichón in Mexico, Mount Pinatubo in the Philippines, Mount Merapi in Indonesia and La Soufrière on the Caribbean island of Saint Vincent.

Consciousness does not emerge from human brains, according to Professor Maria Strømme, a professor of nanotechnology at Uppsala University. Instead, she claims that it exists as a fundamental field. If this is correct, 'mysterious' phenomena such as telepathy, near-death experiences, and even life after death could finally be explained by science.
