In real practice, questions are typically complex and knowledge-intensive, requiring Large Language Models (LLMs) to recognize the multifaceted nature of the question and reason across multiple information sources. Iterative and adaptive retrieval, where LLMs decide when and what to retrieve based on their reasoning, has been shown to be a promising approach to resolve complex, knowledge-intensive questions. However, the performance of such retrieval frameworks is limited by the accumulation of reasoning errors and misaligned retrieval results. To overcome these limitations, we propose TreeRare (Syntax Tree-Guided Retrieval and Reasoning), a framework that utilizes syntax trees to guide information retrieval and reasoning for question answering. Following the principle of compositionality, TreeRare traverses the syntax tree in a bottom-up fashion, and in each node, it generates subcomponent-based queries and retrieves relevant passages to resolve localized uncertainty. A subcomponent question answering module then synthesizes these passages into concise, context-aware evidence. Finally, TreeRare aggregates the evidence across the tree to form a final answer. Experiments across five question answering datasets involving ambiguous or multi-hop reasoning demonstrate that TreeRare achieves substantial improvements over existing state-of-the-art methods.

Harrison Ford isn't impressed by or afraid of artificial intelligence. In a recent interview with The Wall Street Journal, the "Captain America: Brave New World" star was asked if he was planning on securing control of his likeness from studios, and he brushed off the concern. "You don't need artificial intelligence to steal my soul. You can already do it for nickels and dimes with good ideas and talent," he told the outlet. Ford was referring to the 2024 video game "Indiana Jones and the Great Circle," with actor Troy Baker, who provided the voice and motion-capture performance for the character.

Fox News Flash top entertainment and celebrity headlines are here. Glenn Close acknowledged the ever-changing landscape of the entertainment industry during a stop in Park City, Utah for the Sundance Film Festival. The Academy Award-nominated actress has been trying to keep her "equilibrium" lately, ahead of celebrating Sundance Institute icon Michelle Satter at a gala fundraiser. "I'm very lucky to have a job," Close told The Hollywood Reporter. "There were so many people impacted in LA already, and then now with the fires. I was astounded at how few jobs there are in our profession. I'm a big reader of history, and unfortunately, I think not enough people in this country understand the history and what we've just gotten ourselves into. "On top of that is [artificial intelligence].

Nicolas Cage continues to share his fears about artificial intelligence in Hollywood. At the 25th Newport Beach Film Festival on Sunday, the actor gave a speech ahead of his Icon Award reception during the Honors Brunch where he emphasized the need to control your own image and performance as AI rises in popularity with studios. "There is a new technology in town. It's a technology that I didn't have to contend with for 42 years until recently. But these 10 young actors, this generation, most certainly will be, and they are calling it'EBDR.' This technology wants to take your instrument. We are the instruments as film actors. We are not hiding behind guitars and drums," Cage said, per Deadline.

Nicolas Cage knows he's a meme. After making the mistake of googling himself a few years back, the charismatic actor discovered that his big on-screen performances had been translated into single-frame quips and supercuts, taken--like all memes, really--out of context, played for lolz, and in a manner that, frankly, makes Cage seem like a graduate from the Jim Carrey school of rubber-faced acting. "Something like'Nick Cage loses his shit,' where they cherry-pick meltdowns from different movies I'd made over the years," he says. "I get that it's all done for laughs, and in that context it is funny, but at the same time, there's no regard to how the character got there. This, Cage says, is not why he got into making movies.

Three days ago, a TikTok account going by @deeptomcruise began posting video clips of the Hollywood actor Tom Cruise doing everything from golfing, to tripping and telling a joke in what appears to be a men's clothing store in Italy, to performing a magic trick with a coin. In each of the three videos, Cruise delivers his signature maniacal laugh--you know, the one he repeatedly unleashed in that batty Scientology recruitment video years back--before launching into some sort of bit, and in all of them, it looks just like Cruise. There are a few giveaways, of course. Also, his voice is hollow and scratchy, a la that scene in Face/Off where John Travolta-as-Nicolas Cage is trying to adjust his vocals to that Cage-ian timbre. Still, the Cruise TikToks managed to bewilder and horrify a number of people.

You don't need to wait until the summer premiere of Crazy Rich Asians to see Fresh Off the Boat's Constance Wu headline a big-budget movie. Here she is starring in the live-action Ghost in the Shell, and here she is in Luc Besson's Lucy, and here she is as Black Widow in Avengers: Age of Ultron. Yes, those are all films that starred Scarlett Johansson, but not in the corner of the web containing the new social media campaign #SeeAsAmStar, where Wu enjoys a retconned blockbuster career. Deepfakes are mostly associated with scarily realistic pornography featuring the faces of famous actresses superimposed onto the bodies of adult performers. The campaign, which appeared last week, employs the deepfake toolkit for a nobler purpose: the fight for better representation of minorities in pop culture.

The concept of artificial intelligence (AI), specifically machine learning, being used for less-than-worthy causes has come to public attention this past week via viral videos of Nicolas Cage in movie clips. What is so interesting about Nicolas Cage movie clips, I hear you ask. Well, Cage is the star of movies he never made. You can find clips of him as Indiana Jones, James Bond and, um, Lois Lane. Finally, Face/Off makes so much sense.

The future is here -- and it looks like Nicolas Cage. Some online users are taking a new kind of artificial intelligence technology and using it to insert the hammy actor into films and TV shows he didn't actually star in -- basically into anything and everything they can imagine, from classic James Bond films to scenes from "Game of Thrones." Reddit users began posting about and running with the idea on Thursday after one wondered how long it would be before the AI technology, which has already been put to more unscrupulous uses, was used to create a "full Nic Cage movie." "That's actually a very very good idea," another Reddit user responded. While humorous, the clips point to the growing sophistication of the technology -- and its potential uses, both good and bad.

Nicolas Cage is no stranger to internet memes, but it'll be very hard to outdo the current Cage meme sweeping the nation. A piece of software known on the internet as FakeApp utilizes an algorithm that makes it possible to scan a celebrity's face and upload it onto preexisting video content, so naturally people have begun inserting Nicolas Cage into every movie on the planet. Ever want to see Cage as James Bond or Indiana Jones? Well you're in luck because the FakeApp has made it all possible. The AV Club has rounded up the very best Nicolas Cage FakeApp videos, but we've included our two favorites below.
