Federal employees say that flying is still safe despite the strain on air traffic controllers. But expect even more airport delays ahead. It hasn't been a good year for federal aviation safety workers. January saw the worst US commercial airline disaster in decades, quickly followed by sudden layoffs, staffing shortfalls, major technology glitches at one of the nation's busiest airports, and short timelines to rebuild the systems that govern national airspace. It somehow got worse this month, when a stalemate between congressional Republicans and Democrats led to a government shutdown.

Knowledge graphs serve as critical resources supporting intelligent systems, but they can be noisy due to imperfect automatic generation processes. Existing approaches to noise detection often rely on external facts, logical rule constraints, or structural embeddings. These methods are often challenged by imperfect entity alignment, flexible knowledge graph construction, and overfitting on structures. In this paper, we propose to exploit the consistency between entity and relation type information for noise detection, resulting a novel self-supervised knowledge graph denoising method that avoids those problems. We formalize type inconsistency noise as triples that deviate from the majority with respect to type-dependent reasoning along the topological structure. Specifically, we first extract a compact representation of a given knowledge graph via an encoder that models the type dependencies of triples. Then, the decoder reconstructs the original input knowledge graph based on the compact representation. It is worth noting that, our proposal has the potential to address the problems of knowledge graph compression and completion, although this is not our focus. For the specific task of noise detection, the discrepancy between the reconstruction results and the input knowledge graph provides an opportunity for denoising, which is facilitated by the type consistency embedded in our method. Experimental validation demonstrates the effectiveness of our approach in detecting potential noise in real-world data.

An AI chatbot released by the New York City government to help business owners access pertinent information has been spouting falsehoods, at times even misinforming users about actions that are against the law, according to a report from The Markup. The report, which was co-published with the local nonprofit newsrooms Documented and The City, includes numerous examples of inaccuracies in the chatbot's responses to questions relating to housing policies, workers' rights and other topics. Mayor Adams' administration introduced the chatbot in October as an addition to the MyCity portal, which launched in March 2023 as "a one-stop shop for city services and benefits." The chatbot, powered by Microsoft's Azure AI, is aimed at current and aspiring business owners, and was billed as a source of "actionable and trusted information" that comes directly from the city government's sites. But it is a pilot program, and a disclaimer on the website notes that it "may occasionally produce incorrect, harmful or biased content."

The goal of hyperparameter tuning (or hyperparameter optimization) is to optimize the hyperparameters to improve the performance of the machine or deep learning model. spotPython (``Sequential Parameter Optimization Toolbox in Python'') is the Python version of the well-known hyperparameter tuner SPOT, which has been developed in the R programming environment for statistical analysis for over a decade. PyTorch is an optimized tensor library for deep learning using GPUs and CPUs. This document shows how to integrate the spotPython hyperparameter tuner into the PyTorch training workflow. As an example, the results of the CIFAR10 image classifier are used. In addition to an introduction to spotPython, this tutorial also includes a brief comparison with Ray Tune, a Python library for running experiments and tuning hyperparameters. This comparison is based on the PyTorch hyperparameter tuning tutorial. The advantages and disadvantages of both approaches are discussed. We show that spotPython achieves similar or even better results while being more flexible and transparent than Ray Tune.

Every other day, my WhatsApp bursts with messages from friends in Brazil and abroad expressing equal parts of excitement and apprehension as Sunday's Brazilian presidential elections approach. On Wednesday, my best friend who lives in the country's capital, Brasília, texted to say she was scared of wearing red clothes to go vote this weekend because red is the color associated with the Worker's Party of former President Luiz Inácio Lula da Silva. Lula, the current front-runner, has a real, if slim, chance to beat far-right incumbent President Jair Bolsonaro in the first round by getting more than 50 percent of valid votes. "The mood is terrible," she wrote, later adding that in the last 48 hours, four instances of political violence had been recorded across the country. My friend's worries are justified.

Both the meeting with quality assurance testers and an ensuing five-minute studio-wide meeting were led by studio head Brian Raffel, who did not mention unionization. John Obligato, human resources partner at Activision and Raven's primary human resources contact, sat in on both meetings, chiming in at times and saying "some testers may excel" and "we want to make sure we're developing career development paths." Activision Blizzard did not return a request for comment about the two meetings.

Artificial intelligence has completely changed the outlook of various industries. The health sector, education sector, business sector, manufacturing sector, and agricultural sector are largely driven by technology. AI has also created many jobs opportunities for common people. There are a lot of debates on AI and robotics about how they are increasingly taking over jobs. As it removes jobs, it also opens various opportunities for people.

Blockchain, internet of things (IoT), and artificial intelligence (AI) are driving the digital transformation of the post pandemic era. The inevitable convergence of blockchain, IoT, and AI can form an impactful combination of security, interconnectivity, and autonomy to revolutionize the way things are done. 'Synergy' is a word that refers to a collaboration of entities that creates an impact much greater than that possible by the individual entities on their own. The convergence of blockchain, IoT, and AI is just that - a combination of technologies that have the potential to redefine the way businesses, industries, and even economies function, way more than they are already doing. A few applications and concepts have already seen an overlap between these technologies, with promising results.

Olaf Scholz, the centre-left Social Democrat (SPD) candidate to succeed Angela Merkel, is often described as boring, but could be on the verge of a sensational upset after Sunday's election. With polls showing the SPD narrowly ahead of Angela Merkel's CDU-CSU conservative alliance, Scholz may have achieved something many would have thought impossible just a year ago. His SPD scored just 20.5 percent in Germany's last election in 2017 and has had a difficult few years in coalition with the CDU-CSU, but looks on course to win at least 25 percent of the vote this time. "It's going to be a long election night, that's for sure," Scholz said after the first estimates were released. "But this is certain: that many citizens have put their crosses next to the SPD because they want there to be a change in government and also because they want the next chancellor to be called Olaf Scholz."

Olaf Scholz, the centre-left Social Democrat (SPD) candidate to succeed Angela Merkel, is one of Germany's most influential politicians, with a reputation for being meticulous, confident and fiercely ambitious. As finance minister and vice-chancellor under Merkel, he enjoys a close relationship with the chancellor and has even sought to position himself as the true Merkel continuity candidate, despite hailing from a different party. He was pictured recently on the cover of the Sueddeutsche Zeitung magazine adopting Merkel's famous "rhombus" hand gesture -- a stunt that provoked consternation from rivals in Merkel's CDU camp. Nicknamed "Scholzomat" for his robotic speeches, Scholz has hardly stood out for his charisma in the run-up to Sunday's election. But unlike his two main rivals, Armin Laschet of Merkel's CDU-CSU alliance and Annalena Baerbock of the Greens, the 63-year-old has also managed not to make embarrassing mistakes on the campaign trail. As a result, he is now the favourite to head Germany's next coalition government.
