UT Southwestern teaches med students that 'gender is independent of physical structure, chromosomes, or genes'
Nineteen protesters were arrested at the Kentucky Capitol on Wednesday amid a protest against a measure that would ban certain gender care for minors. Documents obtained by Fox News Digital show that University of Texas Southwestern medical students are being taught that gender is independent of physical structure. Fox News Digital obtained the documents via a FOIA request from Do No Harm, a national association of medical professionals that combats "woke" activism in the healthcare system. According to the University of Texas Southwestern Medical Center's Human Structure curriculum, they "explicitly acknowledge the differentiation between the terms sex and gender." RACHEL LEVINE SAYS CHANGING KIDS' GENDERS WILL SOON BE FULLY EMBRACED: 'WHEELS WILL TURN ON THIS' "The latter is a psychological, social, and cultural construct, including self-identification. Gender is independent of physical structure, chromosomes, or genes," curriculum materials read.
Fast Vision Transformers with HiLo Attention
Pan, Zizheng, Cai, Jianfei, Zhuang, Bohan
Vision Transformers (ViTs) have triggered the most recent and significant breakthroughs in computer vision. Their efficient designs are mostly guided by the indirect metric of computational complexity, i.e., FLOPs, which however has a clear gap with the direct metric such as throughput. Thus, we propose to use the direct speed evaluation on the target platform as the design principle for efficient ViTs. Particularly, we introduce LITv2, a simple and effective ViT which performs favourably against the existing state-of-the-art methods across a spectrum of different model sizes with faster speed. At the core of LITv2 is a novel self-attention mechanism, which we dub HiLo. HiLo is inspired by the insight that high frequencies in an image capture local fine details and low frequencies focus on global structures, whereas a multi-head self-attention layer neglects the characteristic of different frequencies. Therefore, we propose to disentangle the high/low frequency patterns in an attention layer by separating the heads into two groups, where one group encodes high frequencies via self-attention within each local window, and another group encodes low frequencies by performing global attention between the average-pooled low-frequency keys and values from each window and each query position in the input feature map. Benefiting from the efficient design for both groups, we show that HiLo is superior to the existing attention mechanisms by comprehensively benchmarking FLOPs, speed and memory consumption on GPUs and CPUs. For example, HiLo is 1.4x faster than spatial reduction attention and 1.6x faster than local window attention on CPUs. Powered by HiLo, LITv2 serves as a strong backbone for mainstream vision tasks including image classification, dense detection and segmentation. Code is available at https://github.com/ziplab/LITv2.
Speaker Profiling in Multiparty Conversations
Kumar, Shivani, Gupta, Rishabh, Akhtar, Md Shad, Chakraborty, Tanmoy
In conversational settings, individuals exhibit unique behaviors, rendering a one-size-fits-all approach insufficient for generating responses by dialogue agents. Although past studies have aimed to create personalized dialogue agents using speaker persona information, they have relied on the assumption that the speaker's persona is already provided. However, this assumption is not always valid, especially when it comes to chatbots utilized in industries like banking, hotel reservations, and airline bookings. This research paper aims to fill this gap by exploring the task of Speaker Profiling in Conversations (SPC). The primary objective of SPC is to produce a summary of persona characteristics for each individual speaker present in a dialogue. To accomplish this, we have divided the task into three subtasks: persona discovery, persona-type identification, and persona-value extraction. Given a dialogue, the first subtask aims to identify all utterances that contain persona information. Subsequently, the second task evaluates these utterances to identify the type of persona information they contain, while the third subtask identifies the specific persona values for each identified type. To address the task of SPC, we have curated a new dataset named SPICE, which comes with specific labels. We have evaluated various baselines on this dataset and benchmarked it with a new neural model, SPOT, which we introduce in this paper. Furthermore, we present a comprehensive analysis of SPOT, examining the limitations of individual modules both quantitatively and qualitatively.
Event-based Simultaneous Localization and Mapping: A Comprehensive Survey
Huang, Kunping, Zhang, Sen, Zhang, Jing, Tao, Dacheng
In recent decades, visual simultaneous localization and mapping (vSLAM) has gained significant interest in both academia and industry. It estimates camera motion and reconstructs the environment concurrently using visual sensors on a moving robot. However, conventional cameras are limited by hardware, including motion blur and low dynamic range, which can negatively impact performance in challenging scenarios like high-speed motion and high dynamic range illumination. Recent studies have demonstrated that event cameras, a new type of bio-inspired visual sensor, offer advantages such as high temporal resolution, dynamic range, low power consumption, and low latency. This paper presents a timely and comprehensive review of event-based vSLAM algorithms that exploit the benefits of asynchronous and irregular event streams for localization and mapping tasks. The review covers the working principle of event cameras and various event representations for preprocessing event data. It also categorizes event-based vSLAM methods into four main categories: feature-based, direct, motion-compensation, and deep learning methods, with detailed discussions and practical guidance for each approach. Furthermore, the paper evaluates the state-of-the-art methods on various benchmarks, highlighting current challenges and future opportunities in this emerging research area.

TieFake: Title-Text Similarity and Emotion-Aware Fake News Detection
Guo, Quanjiang, Kang, Zhao, Tian, Ling, Chen, Zhouguo
Fake news detection aims to detect fake news widely spreading on social media platforms, which can negatively influence the public and the government. Many approaches have been developed to exploit relevant information from news images, text, or videos. However, these methods may suffer from the following limitations: (1) ignore the inherent emotional information of the news, which could be beneficial since it contains the subjective intentions of the authors; (2) pay little attention to the relation (similarity) between the title and textual information in news articles, which often use irrelevant title to attract reader' attention. To this end, we propose a novel Title-Text similarity and emotion-aware Fake news detection (TieFake) method by jointly modeling the multi-modal context information and the author sentiment in a unified framework. Specifically, we respectively employ BERT and ResNeSt to learn the representations for text and images, and utilize publisher emotion extractor to capture the author's subjective emotion in the news content. We also propose a scale-dot product attention mechanism to capture the similarity between title features and textual features. Experiments are conducted on two publicly available multi-modal datasets, and the results demonstrate that our proposed method can significantly improve the performance of fake news detection. Our code is available at https://github.com/UESTC-GQJ/TieFake.
Radar de Parit\'e: An NLP system to measure gender representation in French news stories
Soumah, Valentin-Gabriel, Rao, Prashanth, Eibl, Philipp, Taboada, Maite
We present the Radar de Paritรฉ, an automated Natural Language Processing (NLP) system that measures the proportion of women and men quoted daily in six Canadian French-language media outlets. We outline the system's architecture and detail the challenges we overcame to address French-specific issues, in particular regarding coreference resolution, a new contribution to the NLP literature on French. Our results highlight the underrepresentation of women in news stories, while also illustrating the application of modern NLP methods to measure gender representation and address societal issues. The commonality in most applied NLP research projects is the need to reliably and scalably extract information from unstructured text data. In this paper, we describe one such application: extracting quotes from news stories to quantify gender representation. Gender representation in the media is a long debated topic. From the 1970s, there have been studies into how much women and gender-diverse people are portrayed in news stories, with the general hypothesis that they tend to be underrepresented [1, 2]. There is also research studying how they are represented, i.e., whether sexist or homophobic tropes are present when we discuss women and gender-diverse people [3, 4]. In this work, we tackle one specific aspect of representation: who is quoted and in what proportions. Our starting hypothesis is that we hear less from women than from men in news stories, that is, that men are quoted more often than is to be expected from their proportion in the general population. To fully answer this question, we formulate a quantitative approach, collecting large amounts of representative data and extracting quotes from the unstructured text. This is the goal of the Radar de Paritรฉ. We define quotes as either direct or indirect reproductions of what a person said, and we define that person as a source in news articles. In order to extract quotes, we employ a full NLP pipeline, focusing on parsing to identify speakers, verbs, and quotes, in each news story. We then predict the gender of the speaker (or source), using external genderprediction services.
OpenAI CEO says era of giant AI models is over
Russell Wald, director of the Stanford Institute for Human-Centered AI, sounds off on'The Story.' OpenAI CEO Sam Altman says the age of the giant artificial intelligence model is already over. "I think we're at the end of the era where it's going to be these, like, giant, giant models," he told an audience at the Massachusetts Institute of Technology over Zoom last week. "We'll make them better in other ways." During the same event, Altman also confirmed that his company is not developing Chat GPT-5. "An earlier version of the letter claimed OpenAI is training GPT-5 right now," he said, referencing a letter from billionaire Elon Musk and Apple co-founder Steve Wozniak.
Schools, museums turn to AI to detect guns but tech suffers notable fails
Fox News correspondent Grady Trimble has the latest on fears the technology will spiral out of control on'Special Report.' Schools and museums are installing artificial intelligence that can detect the presence of guns or other weapons in a bid to thwart potential shootings and other violence. Miami's Frost Museum of Science, as well as school districts in states such as Florida, New York and Illinois, have installed various AI tech to monitor for firearms and other weapons through the locations' security cameras. "The AI system monitors all the cameras," Brooks Weisblat, the Miami museum's vice president for technology, told CBS News. "Every tool helps. You know, anything that we can do to further protect the community and our visitors and our staff."
