Radio remains a pervasive medium for mass information dissemination, with AM/FM stations reaching more Americans than either smartphone-based social networking or live television. Increasingly, radio broadcasts are also streamed online and accessed over the Internet. We present WavePulse, a framework that records, documents, and analyzes radio content in real-time. While our framework is generally applicable, we showcase the efficacy of WavePulse in a collaborative project with a team of political scientists focusing on the 2024 Presidential Elections. We use WavePulse to monitor livestreams of 396 news radio stations over a period of three months, processing close to 500,000 hours of audio streams. These streams were converted into time-stamped, diarized transcripts and analyzed to track answer key political science questions at both the national and state levels. Our analysis revealed how local issues interacted with national trends, providing insights into information flow. Our results demonstrate WavePulse's efficacy in capturing and analyzing content from radio livestreams sourced from the Web. Code and dataset can be accessed at \url{https://wave-pulse.io}.

Machine Learning (ML) for Mineral Prospectivity Mapping (MPM) remains a challenging problem as it requires the analysis of associations between large-scale multi-modal geospatial data and few historical mineral commodity observations (positive labels). Recent MPM works have explored Deep Learning (DL) as a modeling tool with more representation capacity. However, these overparameterized methods may be more prone to overfitting due to their reliance on scarce labeled data. While a large quantity of unlabeled geospatial data exists, no prior MPM works have considered using such information in a self-supervised manner. Our MPM approach uses a masked image modeling framework to pretrain a backbone neural network in a self-supervised manner using unlabeled geospatial data alone. After pretraining, the backbone network provides feature extraction for downstream MPM tasks. We evaluated our approach alongside existing methods to assess mineral prospectivity of Mississippi Valley Type (MVT) and Clastic-Dominated (CD) Lead-Zinc deposits in North America and Australia. Our results demonstrate that self-supervision promotes robustness in learned features, improving prospectivity predictions. Additionally, we leverage explainable artificial intelligence techniques to demonstrate that individual predictions can be interpreted from a geological perspective.

Objective: this study has a twofold goal. First, it aims to improve the understanding of the impact of Dementia of type Alzheimer's Disease (AD) on different aspects of the lexicon. Second, it aims to demonstrate that such aspects of the lexicon, when used as features of a machine learning classifier, can help achieve state-of-the-art performance in automatically identifying language samples produced by patients with AD. Methods: data is derived from the ADDreSS challenge, which is a part of the DementiaBank corpus. The used dataset consists of transcripts of Cookie Theft picture descriptions, produced by 54 subjects in the training part and 24 subjects in the test part. The number of narrative samples is 108 in the training set and 48 in the test set. First, the impact of AD on 99 selected lexical features is studied using both the training and testing parts of the dataset. Then some machine learning experiments were conducted on the task of classifying transcribed speech samples with text samples that were produced by people with AD from those produced by normal subjects. Several experiments were conducted to compare the different areas of lexical complexity, identify the subset of features that help achieve optimal performance, and study the impact of the size of the input on the classification. To evaluate the generalization of the models built on narrative speech, two generalization tests were conducted using written data from two British authors, Iris Murdoch and Agatha Christie, and the transcription of some speeches by former President Ronald Reagan. Results: using lexical features only, state-of-the-art classification, F1 and accuracies, of over 91% were achieved in categorizing language samples produced by individuals with AD from the ones produced by healthy control subjects. This confirms the substantial impact of AD on lexicon processing.

Doctors believe Artificial Intelligence is now saving lives, after a major advancement in breast cancer screenings. A.I. is detecting early signs of the disease, in some cases years before doctors would find the cancer on a traditional scan. For every patient visit, physicians spend an average of 16 minutes and 14 seconds using electronic health records to review data and make notes, according to a 2020 study in the Annals of Internal Medicine. Navina, a New York-based medical tech company, has created an artificial intelligence tool to help doctors reclaim some of that time -- and ensure that important data doesn't get missed. The platform, which is also called Navina, uses generative AI to transform how data informs the physician-patient interaction, explained Ronen Lavi, the company's Israel-based CEO.

As part of our AI For Growth executive education series, we interview top executives at leading global companies who have successfully applied AI to grow their enterprises. Today, we sit down with Kevin Scott, Chief Technology Officer at Microsoft. As the CTO of Microsoft, Kevin drives the technology giant's AI strategy and services. In this interview, he focuses on the intersection of AI and IoT and reveals how enterprises have successfully leverage the combination of these two emerging technologies to drive real business value. He also shares insights from his visits to industries ripe for disruption by AI and automation and key learnings for how managers can best prepare their workforces for the future.

First, the futurist Amy Webb told the audience of journalists, librarians and foundation managers that they could easily be duped by the ever-growing purveyors of artificial intelligence. Images of their faces could be affixed to others' bodies, their voices to impostors. Media people have acknowledged to pollsters that they are so focused on the present that they don't pay close attention to what might be in store for them in five, 10 or 20 years. Later in her talk Wednesday before the Knight Media Forum in Miami, Webb told people of color that they weren't thought about when the creators of self-driving cars, GPS navigators, robotics and other such technologies were being developed. "My question is, what does all this mean for communities of color?" (video) asked Sara Lomax-Reese, president and CEO of black talk-formatted WURD radio in Philadelphia. She was one of about 500 at the sold-out conference sponsored by the John S. and James L. Knight Foundation. "It's not good," replied Webb. "Any person of color who's ever felt invisible, you're totally invisible to the networks. Right?" said the author of the 2016 book "The Signals Are Talking: Why Today's Fringe Is Tomorrow's Mainstream: Forecast and Take Action on Tomorrow's Trends, Today."
