Google brings the AI feature that told Americans to eat rocks to six more countries
Google is expanding AI Overviews, the feature that summarizes answers to complex questions from the web and presents them at the top of traditional search results, to six more countries -- India, Japan, Mexico, Indonesia, Brazil and the United Kingdom -- from Thursday with support for local languages as well as English. That's less than three months after AI Overviews launched in the United States and promptly told people to eat rocks and put glue on their pizzas. Bringing them to millions more people begs the question: How do you prevent another glue pizza fiasco in a foreign country? "It's a challenging space," Hema Budaraju, senior director of product management for Search at Google, told Engadget in an interview. "Understanding quality at the scale of the web across all these languages is a hard problem, and integrating LLMs (large language models) is not easy to do. Using AI to better understand languages is pretty critical."
Why the T in ChatGPT is AI's biggest breakthrough - and greatest risk
When ChatGPT first took the world by storm in 2022, its capabilities were so impressive that people happily looked past its awkward name. Yet hidden within those initials lies a key breakthrough responsible for sending artificial intelligence rocketing these past few years โ and potentially a limitation that could see it crashing back to Earth. GPT stands for generative pre-trained transformer, and it is the last word that matters most.
Master the art of fooling AI detectors (with this other AI tool)
Did AI write this article? No--you'd be able to tell. Tools like ChatGPT are notorious for writing text that sounds robotic, repetitive, and just plain awkward. If you've ever had it write your emails or essays (we won't tell), you already know how bad it is. But you might be able to fool some people with this tool that writes realistic AI text.
Hedge funds race to tailor ChatGPT for time-consuming research chores
Chris Pulman used to spend two days prepping previews for central bank meetings. Now it can take the chief economist for macro at Balyasny Asset Management as little as 30 minutes. Thanks to the new amped-up generation of artificial intelligence, chatbots are now carrying out his time-consuming research chores. "We found they're actually substantially more powerful than you think at first," said the Balyasny economist, referring to large language models.

Tian, Jacob-Junqi, Yu, Hao, Orlovskiy, Yury, Vergho, Tyler, Rivera, Mauricio, Goel, Mayank, Yang, Zachary, Godbout, Jean-Francois, Rabbany, Reihaneh, Pelrine, Kellin
This paper develops an agent-based automated fact-checking approach for detecting misinformation. We demonstrate that combining a powerful LLM agent, which does not have access to the internet for searches, with an online web search agent yields better results than when each tool is used independently. Our approach is robust across multiple models, outperforming alternatives and increasing the macro F1 of misinformation detection by as much as 20 percent compared to LLMs without search. We also conduct extensive analyses on the sources our system leverages and their biases, decisions in the construction of the system like the search tool and the knowledge base, the type of evidence needed and its impact on the results, and other parts of the overall process. By combining strong performance with in-depth understanding, we hope to provide building blocks for future search-enabled misinformation mitigation systems.
Inductive Learning of Logical Theories with LLMs: A Complexity-graded Analysis
Gandarela, Joรฃo Pedro, Carvalho, Danilo S., Freitas, Andrรฉ
This work presents a novel systematic methodology to analyse the capabilities and limitations of Large Language Models (LLMs) with feedback from a formal inference engine, on logic theory induction. The analysis is complexity-graded w.r.t. rule dependency structure, allowing quantification of specific inference challenges on LLM performance. Integrating LLMs with formal methods is a promising frontier in the Natural Language Processing field, as an important avenue for improving model inference control and explainability. In particular, inductive learning over complex sets of facts and rules, poses unique challenges for current autoregressive models, as they lack explicit symbolic grounding. While they can be complemented by formal systems, the properties delivered by LLMs regarding inductive learning, are not well understood and quantified. Empirical results indicate that the largest LLMs can achieve competitive results against a SOTA Inductive Logic Programming (ILP) system baseline, but also that tracking long predicate relationship chains is a more difficult obstacle than theory complexity for the LLMs.
Csi-LLM: A Novel Downlink Channel Prediction Method Aligned with LLM Pre-Training
Fan, Shilong, Liu, Zhenyu, Gu, Xinyu, Li, Haozhen
Downlink channel temporal prediction is a critical technology in massive multiple-input multiple-output (MIMO) systems. However, existing methods that rely on fixed-step historical sequences significantly limit the accuracy, practicality, and scalability of channel prediction. Recent advances have shown that large language models (LLMs) exhibit strong pattern recognition and reasoning abilities over complex sequences. The challenge lies in effectively aligning wireless communication data with the modalities used in natural language processing to fully harness these capabilities. In this work, we introduce Csi-LLM, a novel LLM-powered downlink channel prediction technique that models variable-step historical sequences. To ensure effective cross-modality application, we align the design and training of Csi-LLM with the processing of natural language tasks, leveraging the LLM's next-token generation capability for predicting the next step in channel state information (CSI). Simulation results demonstrate the effectiveness of this alignment strategy, with Csi-LLM consistently delivering stable performance improvements across various scenarios and showing significant potential in continuous multi-step prediction.
Level Up Your Tutorials: VLMs for Game Tutorials Quality Assessment
Cambrin, Daniele Rege, Militone, Gabriele Scaffidi, Colomba, Luca, Malnati, Giovanni, Apiletti, Daniele, Garza, Paolo
Designing effective game tutorials is crucial for a smooth learning curve for new players, especially in games with many rules and complex core mechanics. Evaluating the effectiveness of these tutorials usually requires multiple iterations with testers who have no prior knowledge of the game. Recent Vision-Language Models (VLMs) have demonstrated significant capabilities in understanding and interpreting visual content. VLMs can analyze images, provide detailed insights, and answer questions about their content. They can recognize objects, actions, and contexts in visual data, making them valuable tools for various applications, including automated game testing. In this work, we propose an automated game-testing solution to evaluate the quality of game tutorials. Our approach leverages VLMs to analyze frames from video game tutorials, answer relevant questions to simulate human perception, and provide feedback. This feedback is compared with expected results to identify confusing or problematic scenes and highlight potential errors for developers. In addition, we publish complete tutorial videos and annotated frames from different game versions used in our tests. This solution reduces the need for extensive manual testing, especially by speeding up and simplifying the initial development stages of the tutorial to improve the final game experience.
MAG-SQL: Multi-Agent Generative Approach with Soft Schema Linking and Iterative Sub-SQL Refinement for Text-to-SQL
Xie, Wenxuan, Wu, Gaochen, Zhou, Bowen
Recent In-Context Learning based methods have achieved remarkable success in Text-to-SQL task. However, there is still a large gap between the performance of these models and human performance on datasets with complex database schema and difficult questions, such as BIRD. Besides, existing work has neglected to supervise intermediate steps when solving questions iteratively with question decomposition methods, and the schema linking methods used in these works are very rudimentary. To address these issues, we propose MAG-SQL, a multi-agent generative approach with soft schema linking and iterative Sub-SQL refinement. In our framework, an entity-based method with tables' summary is used to select the columns in database, and a novel targets-conditions decomposition method is introduced to decompose those complex questions. Additionally, we build a iterative generating module which includes a Sub-SQL Generator and Sub-SQL Refiner, introducing external oversight for each step of generation. Through a series of ablation studies, the effectiveness of each agent in our framework has been demonstrated. When evaluated on the BIRD benchmark with GPT-4, MAG-SQL achieves an execution accuracy of 61.08%, compared to the baseline accuracy of 46.35% for vanilla GPT-4 and the baseline accuracy of 57.56% for MAC-SQL. Besides, our approach makes similar progress on Spider.
FactorLLM: Factorizing Knowledge via Mixture of Experts for Large Language Models
Zhao, Zhongyu, Dong, Menghang, Zhang, Rongyu, Zheng, Wenzhao, Zhang, Yunpeng, Yang, Huanrui, Du, Dalong, Keutzer, Kurt, Zhang, Shanghang
Recent research has demonstrated that Feed-Forward Networks (FFNs) in Large Language Models (LLMs) play a pivotal role in storing diverse linguistic and factual knowledge. Conventional methods frequently face challenges due to knowledge confusion stemming from their monolithic and redundant architectures, which calls for more efficient solutions with minimal computational overhead, particularly for LLMs. In this paper, we explore the FFN computation paradigm in LLMs and introduce FactorLLM, a novel approach that decomposes well-trained dense FFNs into sparse sub-networks without requiring any further modifications, while maintaining the same level of performance. Furthermore, we embed a router from the Mixture-of-Experts (MoE), combined with our devised Prior-Approximate (PA) loss term that facilitates the dynamic activation of experts and knowledge adaptation, thereby accelerating computational processes and enhancing performance using minimal training data and fine-tuning steps. FactorLLM thus enables efficient knowledge factorization and activates select groups of experts specifically tailored to designated tasks, emulating the interactive functional segmentation of the human brain. Extensive experiments across various benchmarks demonstrate the effectiveness of our proposed FactorLLM which achieves comparable performance to the source model securing up to 85% model performance while obtaining over a 30% increase in inference speed.
