Addressing the issue of hallucinations in large language models (LLMs) is a critical challenge. As the cognitive mechanisms of hallucination have been related to memory, here we explore hallucination for LLM that is enabled with explicit memory mechanisms. We empirically demonstrate that by simply scaling the readout vector that constrains generation in a memory-augmented LLM decoder, hallucination mitigation can be achieved in a training-free manner. Our method is geometry-inspired and outperforms a state-of-the-art LLM editing method on the task of generation of Wikipedia-like biography entries both in terms of generation quality and runtime complexity.

In September, a "bespoke AI nutrition" store opened in beleaguered downtown San Francisco to much fanfare, promising smoothie concoctions generated by AI and a much-needed boost to the area. Less than two months later, it has seemingly closed without explanation. BetterBlends advertised "Your Smoothie, powered by AI" and received positive press upon its opening, ginning up excitement for a new business and a novel use of artificial intelligence. Its AI model would take customer orders and preferences to generate a smoothie recipe that would then be blended by hand by co-founders Michael Parlato and Clayton Reynolds, who worked in the shop. But now the storefront sits empty. On Friday 20 October, the locked doors to BetterBlends featured a sign that read "temporarily closed", stating the shop would reopen in one hour – but sources in the neighborhood said the storefront had been closed for more than three weeks.

The California Public Utilities Commission--a state agency that regulates power, water, and telecommunications companies, as well as movers, taxicabs, rideshare services, and self-driving cars--is headquartered in a large, curved building on Van Ness Avenue, in San Francisco, that looks a bit like a sun visor. Last Thursday morning, a small group of protesters gathered on the steps in advance of the commission's vote on whether to allow the autonomous-vehicle companies Cruise and Waymo to expand their fleets, and charge for rides, like a taxi service, in the city. A man holding a megaphone denounced corporate greed, while other people unfurled hand-painted banners. One depicted a dead dog lying in the street--possibly a reference to the small dog killed earlier this summer by a Waymo car. Another showed an autonomous vehicle in flames bearing down on a crowd of firemen, police officers, and taxi-drivers.

Author Brad Meltzer reacts after the York, Pa., school district banned his children's book, 'I Am Rosa Parks,' along with others that involve race and history. A school district in Iowa used artificial intelligence to examine library books and help identify which contain sexually explicit material that needed to be removed from school property to comply with a new state law. In May, Republican Iowa Gov. Kim Reynolds signed a parental rights bill, which requires all books in public school libraries describing sex acts be removed. The law took effect July 1. To comply with the new law, the Mason City Community School District got creative and used artificial intelligence technology to sift through voluminous amounts of text and determine which books were subject to removal.

Get ready, San Francisco: The state government on Thursday approved a major expansion of driverless robotaxi service throughout the city. And get ready, Los Angeles: The industry is planning to push for driverless rides here as soon as it gets permits to do so. The state's green light, on a 3-1 vote by the California Public Utilities Commission, signals a historic turning point for the robotaxi business as it evolves from fascinating experiment to commercial reality. It also marks the beginning of a grand experiment in public safety as thousands of multi-ton vehicles operated via artificial intelligence attempt to safely negotiate the hills and narrow streets of San Francisco. It highlights California's messy multiagency regulation of new automobile technology: Two agencies are in charge of the robotaxi business, the CPUC and the California Department of Motor Vehicles.

In The Matrix, Neo (Keanu Reeves) wanders through crowded city streets, bumping past sailors and women in red dresses, before learning that they aren't real people, but instead simulations. In future Keanu Reeves movies, it's possible that everyone around him might be simulated, too. On July 13, Hollywood producers advertised a "groundbreaking AI proposal" involving the "use of digital replicas or…digital alterations of a performance." The SAG-AFTRA union lambasted the proposal, accusing the studios of simply trying to replace background actors with AI. Studios could scan an actor, pay them for a day, and then simply use AI to insert them into the rest of the film, Duncan Crabtree-Ireland, SAG-AFTRA's chief negotiator, said in a press conference. The Alliance of Motion Picture and Television Producers responded that this characterization was inaccurate and that they would "establish a comprehensive set of provisions that require informed consent and fair compensation when a'digital replica'" or similar AI technology is used.

The future of Hollywood looks a lot like Deepfake Ryan Reynolds selling you a Tesla. In a video, since removed but widely shared on Twitter, the actor is bespectacled in thick black frames, his mouth mouthing independently from his face, hawking electric vehicles: "How much do you think it would cost to own a car that's this fucking awesome?" On the verisimilitude scale, the video, which originally circulated last month, registered as blatantly unreal. Then its creator, financial advice YouTuber Kevin Paffrath, revealed he had made it as a ploy to attract the gaze of Elon Musk. Elsewhere on Twitter, people beseeched Reynolds to sue.

You may have already seen them in restaurants: waist-high machines that can greet guests, lead them to their tables, deliver food and drinks and ferry dirty dishes to the kitchen. Some have cat-like faces and even purr when you scratch their heads. But are robot waiters the future? It's a question the restaurant industry is increasingly trying to answer. Many think robot waiters are the solution to the industry's labor shortages.

"The ChatGPT Phenomenon" is a book that explores the inner workings of OpenAI's language model, ChatGPT. Written by computer science expert, Jake Reynolds, the book delves into the technical details of how ChatGPT works, and how it has revolutionized the field of natural language processing. The book starts by introducing the reader to the basics of language models and the history of artificial intelligence, setting the stage for the emergence of ChatGPT. The author then goes on to explain the architecture of ChatGPT and how it differs from other language models, highlighting its unique strengths and capabilities. As the book progresses, the author provides practical examples and case studies of how ChatGPT is being used in various industries, such as chatbots, content creation, and language translation.

The use of data would take a central role in a Labour government's industrial strategy, according to shadow business secretary Jonathan Reynolds A council would also be set up on a statutory footing to oversee the strategy and ensure it isn't abandoned at a later date. The opposition party said if it were to win the next general election, it would make "harnessing data for the public good" a key mission in its industrial strategy. Reynolds announced Labour's industrial strategy at the Labour Party conference in Liverpool. "It's a real industrial strategy – with ambition and the means to achieve it," he said. A key part of this, according to Reynolds, is using data.
