News media, especially video news media, have penetrated into every aspect of daily life, which also brings the risk of fake news. Therefore, multimodal fake news detection has recently garnered increased attention. However, the existing datasets are comprised of user-uploaded videos and contain an excess amounts of superfluous data, which introduces noise into the model training process. To address this issue, we construct a dataset named Official-NV, comprising officially published news videos. The crawl officially published videos are augmented through the use of LLMs-based generation and manual verification, thereby expanding the dataset. Furthermore, the proposed dataset is benchmarked against several baselines to demonstrate its effectiveness in multimodal news detection.

OpenAI has announced significant changes to its safety and security practices, including the establishment of a new independent board oversight committee. This move comes with a notable shift: CEO Sam Altman is no longer part of the safety committee, marking a departure from the previous structure. The newly formed Safety and Security Committee (SSC) will be chaired by Zico Kolter, Director of the Machine Learning Department at Carnegie Mellon University. Other key members include Quora CEO Adam D'Angelo, retired US Army General Paul Nakasone, and Nicole Seligman, former EVP and General Counsel of Sony Corporation. This new committee replaces the previous Safety and Security Committee that was formed in June 2024, which included Altman among its members.

Today, Microsoft is announcing "Wave 2" of its Microsoft 365 Copilot AI innovation, which is geared towards users who are paying for a Microsoft 365 Copilot Pro subscription. But one feature, known as Pages, may be available to business customers who use Copilot without a subscription. The subtext of Pages -- and the overall theme of the new Copilot wave in general -- is that Copilot's AI contributions matter. Normally, any advice provided by Copilot remains within Copilot and only for a short time. Microsoft characterizes Copilot's output as "ephemeral," signifying something that eventually passes over.

Think of any topic vaguely related to raising kids imaginable, and there's probably a post about it on Mumsnet, the long-running, enormously popular, controversy-spurring UK-based parenting forum for mothers. Over its more than two decade-long history, Mumsnet has amassed an archive of more than six billion words written by its highly engaged user base, on topics such as dirty diapers and lazy husbands. This spring, after Mumsnet discovered that AI companies were scraping its data, the company says it decided to try to strike licensing deals with some of the major players in the space, including OpenAI, which initially expressed willingness to explore an arrangement after Mumsnet first reached out. After talks with OpenAI fell apart, Mumsnet in July announced its intention to pursue legal action. According to Mumsnet, during those early conversations, an OpenAI strategic partnership lead told the company that datasets over 1 billion words were of interest to the AI giant.

In the past couple of years, regulators have been caught off guard again and again as tech companies compete to launch ever more advanced AI models. It's only a matter of time before labs release another round of models that pose new regulatory challenges. We're likely just weeks away, for example, from OpenAI's release of ChatGPT-5, which promises to push AI capabilities further than ever before. As it stands, it seems there's little anyone can do to delay or prevent the release of a model that poses excessive risks. Testing AI models before they're released is a common approach to mitigating certain risks, and it may help regulators weigh up the costs and benefits--and potentially block models from being released if they're deemed too dangerous.

This work investigates the identification of Charismatic Leadership Tactics (CLTs) in natural language using a fine-tuned Bidirectional Encoder Representations from Transformers (BERT) model. Based on an own extensive corpus of CLTs generated and curated for this task, our methodology entails training a machine learning model that is capable of accurately identifying the presence of these tactics in natural language. A performance evaluation is conducted to assess the effectiveness of our model in detecting CLTs. We find that the total accuracy over the detection of all CLTs is 98.96\% The results of this study have significant implications for research in psychology and management, offering potential methods to simplify the currently elaborate assessment of charisma in texts.

Traditional methods for eliciting people's opinions face a trade-off between depth and scale: structured surveys enable large-scale data collection but limit respondents' ability to express unanticipated thoughts in their own words, while conversational interviews provide deeper insights but are resource-intensive. This study explores the potential of replacing human interviewers with large language models (LLMs) to conduct scalable conversational interviews. Our goal is to assess the performance of AI Conversational Interviewing and to identify opportunities for improvement in a controlled environment. We conducted a small-scale, in-depth study with university students who were randomly assigned to be interviewed by either AI or human interviewers, both employing identical questionnaires on political topics. Various quantitative and qualitative measures assessed interviewer adherence to guidelines, response quality, participant engagement, and overall interview efficacy. The findings indicate the viability of AI Conversational Interviewing in producing quality data comparable to traditional methods, with the added benefit of scalability. Based on our experiences, we present specific recommendations for effective implementation.

In high-stake environments like emergency response or elder care, the integration of large language model (LLM), revolutionize risk assessment, resource allocation, and emergency responses in Human Activity Recognition (HAR) systems by leveraging data from various wearable sensors. We propose a conceptual framework that utilizes various wearable devices, each considered as a single dimension, to support a multidimensional learning approach within HAR systems. By integrating and processing data from these diverse sources, LLMs can process and translate complex sensor inputs into actionable insights. This integration mitigates the inherent uncertainties and complexities associated with them, and thus enhancing the responsiveness and effectiveness of emergency services. This paper sets the stage for exploring the transformative potential of LLMs within HAR systems in empowering emergency workers to navigate the unpredictable and risky environments they encounter in their critical roles.

Accurate interpretation of lab results is crucial in clinical medicine, yet most patient portals use universal normal ranges, ignoring factors like age and gender. This study introduces Lab-AI, an interactive system that offers personalized normal ranges using Retrieval-Augmented Generation (RAG) from credible health sources. Lab-AI has two modules: factor retrieval and normal range retrieval. We tested these on 68 lab tests--30 with conditional factors and 38 without. For tests with factors, normal ranges depend on patient-specific information. Our results show GPT-4-turbo with RAG achieved a 0.95 F1 score for factor retrieval and 0.993 accuracy for normal range retrieval. GPT-4-turbo with RAG outperformed the best non-RAG system by 29.1% in factor retrieval and showed 60.9% and 52.9% improvements in question-level and lab-level performance, respectively, for normal range retrieval. These findings highlight Lab-AI's potential to enhance patient understanding of lab results. Introduction The Health Information Technology for Economic and Clinical Health (HITECH) Act of 2009 played a key role in promoting the adoption and meaningful use of electronic health records (EHRs) throughout the U.S. healthcare system. Through the Medicare and Medicaid EHR Incentive Programs, the Act provided financial incentives that facilitated widespread EHR adoption.

Healthcare monitoring is crucial for early detection, timely intervention, and the ongoing management of health conditions, ultimately improving individuals' quality of life. Recent research shows that Large Language Models (LLMs) have demonstrated impressive performance in supporting healthcare tasks. However, existing LLM-based healthcare solutions typically rely on cloud-based systems, which raise privacy concerns and increase the risk of personal information leakage. As a result, there is growing interest in running these models locally on devices like mobile phones and wearables to protect users' privacy. Small Language Models (SLMs) are potential candidates to solve privacy and computational issues, as they are more efficient and better suited for local deployment. However, the performance of SLMs in healthcare domains has not yet been investigated. This paper examines the capability of SLMs to accurately analyze health data, such as steps, calories, sleep minutes, and other vital statistics, to assess an individual's health status. Our results show that, TinyLlama, which has 1.1 billion parameters, utilizes 4.31 GB memory, and has 0.48s latency, showing the best performance compared other four state-of-the-art (SOTA) SLMs on various healthcare applications. Our results indicate that SLMs could potentially be deployed on wearable or mobile devices for real-time health monitoring, providing a practical solution for efficient and privacy-preserving healthcare.
