What Military Drones Can Teach Self-Driving Cars
Self-driving cars often struggle with situations that are commonplace for human drivers. When confronted with construction zones, school buses, power outages, or misbehaving pedestrians, these vehicles often behave unpredictably, leading to crashes or freezing events, causing significant disruption to local traffic and possibly blocking first responders from doing their jobs. Because self-driving cars cannot successfully … Devamını oku
Perseverance Smashes Autonomous Driving Record on Mars
This article is part of our exclusive IEEE Journal Watch series in partnership with IEEE Xplore. In past missions to Mars, like with the Curiosity and Opportunity rovers, the robots relied mostly on human instructions from millions of miles away in order to safely navigate the Martian landscape. The Perseverance rover, on the other hand, … Devamını oku

A simple hand photo may be the key to detecting a serious disease
Researchers at Kobe University have developed an AI system that can detect acromegaly, a rare hormone disorder, by analyzing photos of the back of the hand and a clenched fist. The disease often develops slowly and can take years to diagnose, even though untreated cases may shorten life expectancy.
Scientists build a “periodic table” for AI
Choosing the right method for multimodal AI—systems that combine text, images, and more—has long been trial and error. Emory physicists created a unifying mathematical framework that shows many AI techniques rely on the same core idea: compress data while preserving what’s most predictive. Their “control knob” approach helps researchers design better algorithms, use less data, … Devamını oku
ChatGPT as a therapist? New study reveals serious ethical risks
As millions turn to ChatGPT and other AI chatbots for therapy-style advice, new research from Brown University raises a serious red flag: even when instructed to act like trained therapists, these systems routinely break core ethical standards of mental health care. In side-by-side evaluations with peer counselors and licensed psychologists, researchers uncovered 15 distinct ethical … Devamını oku
