The dynamics of meaning through time: Assessment of Large Language Models

arXiv.org Artificial Intelligence

Understanding how large language models (LLMs) grasp the historical context of concepts and their semantic evolution is essential in advancing artificial intelligence and linguistic studies. This study aims to evaluate the capabilities of various LLMs in capturing temporal dynamics of meaning, specifically how they interpret terms across different time periods. We analyze a diverse set of terms from multiple domains, using tailored prompts and measuring responses through both objective metrics (e.g., perplexity and word count) and subjective human expert evaluations. Our comparative analysis includes prominent models like ChatGPT, GPT-4, Claude, Bard, Gemini, and Llama. Findings reveal marked differences in each model's handling of historical context and semantic shifts, highlighting both strengths and limitations in temporal semantic understanding. These insights offer a foundation for refining LLMs to better address the evolving nature of language, with implications for historical text analysis, AI design, and applications in digital humanities.


OVO-Bench: How Far is Your Video-LLMs from Real-World Online Video Understanding?

arXiv.org Artificial Intelligence

Temporal Awareness, the ability to reason dynamically based on the timestamp when a question is raised, is the key distinction between offline and online video LLMs. Unlike offline models, which rely on complete videos for static, post hoc analysis, online models process video streams incrementally and dynamically adapt their responses based on the timestamp at which the question is posed. Despite its significance, temporal awareness has not been adequately evaluated in existing benchmarks. To fill this gap, we present OVO-Bench (Online-VideO-Benchmark), a novel video benchmark that emphasizes the importance of timestamps for advanced online video understanding capability benchmarking. OVO-Bench evaluates the ability of video LLMs to reason and respond to events occurring at specific timestamps under three distinct scenarios: (1) Backward tracing: trace back to past events to answer the question. (2) Real-time understanding: understand and respond to events as they unfold at the current timestamp. (3) Forward active responding: delay the response until sufficient future information becomes available to answer the question accurately. OVO-Bench comprises 12 tasks, featuring 644 unique videos and approximately human-curated 2,800 fine-grained meta-annotations with precise timestamps. We combine automated generation pipelines with human curation. With these high-quality samples, we further developed an evaluation pipeline to systematically query video LLMs along the video timeline. Evaluations of nine Video-LLMs reveal that, despite advancements on traditional benchmarks, current models struggle with online video understanding, showing a significant gap compared to human agents. We hope OVO-Bench will drive progress in video LLMs and inspire future research in online video reasoning. Our benchmark and code can be accessed at https://github.com/JoeLeelyf/OVO-Bench.


Spatial Information Integration in Small Language Models for Document Layout Generation and Classification

arXiv.org Artificial Intelligence

Document layout understanding is a field of study that analyzes the spatial arrangement of information in a document hoping to understand its structure and layout. Models such as LayoutLM (and its subsequent iterations) can understand semi-structured documents with SotA results; however, the lack of open semi-structured data is a limitation in itself. While semi-structured data is common in everyday life (balance sheets, purchase orders, receipts), there is a lack of public datasets for training machine learning models for this type of document. In this investigation we propose a method to generate new, synthetic, layout information that can help overcoming this data shortage. According to our results, the proposed method performs better than LayoutTransformer, another popular layout generation method. We also show that, in some scenarios, text classification can improve when supported by bounding box information.


Exploring the Potential Role of Generative AI in the TRAPD Procedure for Survey Translation

arXiv.org Artificial Intelligence

This paper explores and assesses in what ways generative AI can assist in translating survey instruments. Writing effective survey questions is a challenging and complex task, made even more difficult for surveys that will be translated and deployed in multiple linguistic and cultural settings. Translation errors can be detrimental, with known errors rendering data unusable for its intended purpose and undetected errors leading to incorrect conclusions. A growing number of institutions face this problem as surveys deployed by private and academic organizations globalize, and the success of their current efforts depends heavily on researchers' and translators' expertise and the amount of time each party has to contribute to the task. Thus, multilinguistic and multicultural surveys produced by teams with limited expertise, budgets, or time are at significant risk for translation-based errors in their data. We implement a zero-shot prompt experiment using ChatGPT to explore generative AI's ability to identify features of questions that might be difficult to translate to a linguistic audience other than the source language. We find that ChatGPT can provide meaningful feedback on translation issues, including common source survey language, inconsistent conceptualization, sensitivity and formality issues, and nonexistent concepts. In addition, we provide detailed information on the practicality of the approach, including accessing the necessary software, associated costs, and computational run times. Lastly, based on our findings, we propose avenues for future research that integrate AI into survey translation practices.


AI-generated Image Detection: Passive or Watermark?

arXiv.org Artificial Intelligence

While text-to-image models offer numerous benefits, they also pose significant societal risks. Detecting AI-generated images is crucial for mitigating these risks. Detection methods can be broadly categorized into passive and watermark-based approaches: passive detectors rely on artifacts present in AI-generated images, whereas watermark-based detectors proactively embed watermarks into such images. A key question is which type of detector performs better in terms of effectiveness, robustness, and efficiency. However, the current literature lacks a comprehensive understanding of this issue. In this work, we aim to bridge that gap by developing ImageDetectBench, the first comprehensive benchmark to compare the effectiveness, robustness, and efficiency of passive and watermark-based detectors. Our benchmark includes four datasets, each containing a mix of AI-generated and non-AI-generated images. We evaluate five passive detectors and four watermark-based detectors against eight types of common perturbations and three types of adversarial perturbations. Our benchmark results reveal several interesting findings. For instance, watermark-based detectors consistently outperform passive detectors, both in the presence and absence of perturbations. Based on these insights, we provide recommendations for detecting AI-generated images, e.g., when both types of detectors are applicable, watermark-based detectors should be the preferred choice. Our code and data are publicly available at https://github.com/moyangkuo/ImageDetectBench.git.


Consistency Checks for Language Model Forecasters

arXiv.org Machine Learning

Forecasting is a task that is difficult to evaluate: the ground truth can only be known in the future. Recent work showing LLM forecasters rapidly approaching human-level performance begs the question: how can we benchmark and evaluate these forecasters instantaneously? Following the consistency check framework, we measure the performance of forecasters in terms of the consistency of their predictions on different logically-related questions. We propose a new, general consistency metric based on arbitrage: for example, if a forecasting AI illogically predicts that both the Democratic and Republican parties have 60% probability of winning the 2024 US presidential election, an arbitrageur can trade against the forecaster's predictions and make a profit. We build an automated evaluation system that generates a set of base questions, instantiates consistency checks from these questions, elicits the predictions of the forecaster, and measures the consistency of the predictions. We then build a standard, proper-scoring-rule forecasting benchmark, and show that our (instantaneous) consistency metrics correlate with LLM forecasters' ground truth Brier scores (which are only known in the future). We also release a consistency benchmark that resolves in 2028, providing a long-term evaluation tool for forecasting.

Before Las Vegas, Intel Analysts Warned That Bomb Makers Were Turning to AI

WIRED

Using a series of prompts six days before he died by suicide outside the main entrance of the Trump International Hotel in Las Vegas, Matthew Livelsberger, a highly decorated US Army Green Beret from Colorado, consulted with an artificial intelligence on the best ways to turn a rented Cybertruck into a four-ton vehicle-borne explosive. According to documents obtained exclusively by WIRED, US intelligence analysts have been issuing warnings about this precise scenario over the past year--and among their concerns are that AI tools could be used by racially or ideologically motivated extremists to target critical infrastructure, in particular the power grid. "We knew that AI was going to change the game at some point or another in, really, all of our lives," Sheriff Kevin McMahill of the Las Vegas Metropolitan Police Department told reporters on Tuesday. Copies of his exchanges with OpenAI's ChatGPT show that Livelsberger, 37, pursued information on how to amass as much explosive material as he legally could while en route to Las Vegas, as well as how best to set it off using the Desert Eagle gun discovered in the Cybertruck following his death. Screenshots shared by McMahill's office reveal Livelsberger prompting ChatGPT for information on Tannerite, a reactive compound typically used for target practice.


How OpenAI's Sam Altman Is Thinking About AGI and Superintelligence in 2025

TIME - Tech

OpenAI CEO Sam Altman recently published a post on his personal blog reflecting on AI progress and his predictions for how the technology will impact humanity's future. "We are now confident we know how to build AGI [artificial general intelligence] as we have traditionally understood it,"Altman wrote. He added that OpenAI, the company behind ChatGPT, is beginning to turn its attention to superintelligence. While there is no universally accepted definition for AGI, OpenAI has historically defined it as "a highly autonomous system that outperforms humans at most economically valuable work." Although AI systems already outperform humans in narrow domains, such as chess, the key to AGI is generality.


Sam Altman's sister is suing the OpenAI CEO alleging sexual abuse

Engadget

Annie Altman, the sister of OpenAI founder and CEO Sam Altman, has sued her brother accusing him of sexually assaulting her when she was a minor. In a complaint filed this week with a Missouri federal court, Annie Altman alleges her older brother committed "numerous acts of rape, sexual assault, sexual abuse, molestation, sodomy, and battery" from 1997 to 2006, with the abuse starting when she was only three years old. In a joint statement he made alongside his mother and two younger brothers, Sam Altman said "all of [Annie's] claims are utterly untrue." The Altmans say they've tried to support Annie in "many ways" over the years, including by offering direct financial assistance. My sister has filed a lawsuit against me.
