ICEYE, the global leader in SAR satellite operations for Earth Observation and persistent monitoring, today introduces its Dwell Fine imaging mode, which adds to the unique capabilities of Dwell mode and builds on the release of Spot Fine, launched in June 2023. With a 50-centimeter resolution, Dwell Fine enables a deeper understanding of changes on the Earth’s surface, identification of specific models of aircraft on the ground and ships at sea, and exploration of human-made structures, such as vehicles and buildings, against natural backgrounds, such as tree canopy and vegetation.
ICEYE’s Dwell Fine is unique in commercial SAR satellite imagery. As a satellite orbits the Earth in Dwell Fine mode its radar signals focus on a defined area of the planet’s surface to create an image for 25 seconds – in contrast to the usual 10 seconds for a standard Spot image. Thanks to the longer duration imaging mode, Dwell Fine users can determine the shape of an aircraft’s fuselage, wings, stabilizers, and engines; recognize narrow objects like power lines and antennas; or evaluate the extent and nature of damage to civil infrastructure. Short videos, composed of multiple images taken during collection and delivered as part of the Dwell Fine services, can detect vessels’ movement, direction, and speed.
With its many practical applications, Dwell Fine can detect and emphasize the differences between human-made and natural features. And because images in Dwell mode are taken from a much more comprehensive range of angles, it can perceive objects through gaps in the trees and foliage.
Owner and operator of the world’s largest constellation of SAR satellites, ICEYE first introduced its Dwell mode in May 2023. With the introduction of Dwell Fine less than a year later, ICEYE underlines its commitment to constant innovation in serving private and public sector organizations globally with the most advanced commercial Earth Observation capabilities and SAR satellite imagery.
John Cartwright, ICEYE’s SVP and Head of Data Product, said: “Dwell is a first-in-the-world capability that just evolved into an even better one with the introduction of Dwell Fine. Sharpening the resolution down from one meter to 50 centimeters produces SAR satellite images with incredible clarity. This – combined with the ability of ICEYE satellites to observe any location on Earth every few hours, day or night, and in any weather – enables a level of change detection that’s never been possible before.”
ICEYE’s radar antennae are one-of-a-kind in the SAR satellite sector, controlled by software to direct the radar beams to areas of interest as needed. This technology confers unique capabilities in the sector and provides greater versatility in imaging modes – ranging from the fine granularity of Dwell Fine to views covering tens of thousands of square kilometers.

Researchers build AI-driven sarcasm detector

Artificial intelligence has made remarkable strides, from passing bar exams to reading bedtime stories with emotion. Yet, despite these feats, it still falls short of matching the intricate nuances of human communication—particularly, the art of sarcasm.
However, researchers in the Netherlands are determined to change that narrative. They have developed an AI-driven sarcasm detector that can discern when sarcasm is being used, a feat previously thought to be exclusive to human cognition.
Matt Coler, from the University of Groningen’s speech technology lab, expresses excitement about the project’s progress. He emphasizes the importance of understanding sarcasm, a pervasive aspect of human discourse, to facilitate seamless communication between humans and machines.
Recognizing sarcasm poses challenges due to its subtlety, especially in text-based interactions where cues like tone and facial expressions are absent. To overcome this, researchers trained their AI using a combination of text, audio, and emotional content from popular sitcoms like Friends and The Big Bang Theory.
The AI, trained on annotated data from these shows, demonstrated an impressive ability to detect sarcasm in unlabelled exchanges from the sitcoms, achieving an accuracy rate of nearly 75%. Further enhancements are underway, including incorporating visual cues like eyebrow movements and smirks, to improve accuracy even more.
Beyond enhancing interactions with AI assistants, this technology holds potential for detecting negative language and identifying instances of abuse or hate speech. However, as AI becomes more adept at understanding sarcasm, questions arise about its potential to wield sarcasm itself.
Coler muses about the implications of machines responding with sarcasm, raising concerns about clarity in communication. Nonetheless, advancements in AI-driven sarcasm detection offer promising prospects for improving human-machine interactions and bridging the gap between artificial and human intelligence.

AI, bias and experiments: how Women in News is tackling tech’s inbuilt stereotypes

Issues surrounding bias in AI are deeply rooted in the accuracy, trustworthiness, and quality of data, which, if overlooked, can significantly skew outcomes. Lyndsey Jones, an AI author and transformation coach, delves into these concerns, offering valuable insights for newsrooms on monitoring and reviewing data.
Madhumita Murgia, an AI journalist and the first artificial intelligence editor of the Financial Times, sheds light on how women, migrants, precarious workers, and minority groups are disproportionately affected by the technical limitations of Generative AI. Murgia emphasizes the lack of representation of these groups in the development process of AI technologies, highlighting the need for inclusive participation.
WAN-IFRA Women In News workshops on the Age of AI in the newsroom have brought bias effects to the forefront. Through the Digital ABCs training program, media professionals are equipped with skills to navigate the digital landscape and drive organizational change.
A newly launched module focuses on AI, with over 100 participants in eastern Europe taking part, now extended to journalists in parts of Africa, the Middle East, and Southeast Asia. Instances of bias surfaced during the training, such as generating offensive avatars and misinterpretation of accents in AI tools.
Google CEO Sundar Pichai’s acknowledgment of biased AI tools reflects ongoing concerns in the industry. Timnet Gebru’s dismissal from Google for highlighting biases further underscores the need for vigilance in addressing these issues.
Diverse teams in WIN’s Age of AI program are experimenting with various tools like fact-checking and enhancing staff skill sets in AI usage. Projects under consideration for further EU funding include a video lab for content amplification and an AI avatar for journalist safety.
Media companies must ensure diverse staff collaboration when testing AI tools. Quotas for women in AI research and cross-border partnerships may be necessary for smaller media groups to compete effectively.
Journalists can take steps to improve content quality by examining storytelling practices and ensuring diversity in sources and representation. Consistency of data collection across departments and assessing biases in data sets are crucial for ethical AI usage in journalism. Ultimately, AI tools should be used to enhance journalism’s quality and integrity, rather than generating clickbait or misinformation.
