Your online order arrives damaged, so you request a refund. What often follows is an artificial intelligence workflow involving multiple AI models: One model checks your request against company policy, another analyzes the image you uploaded, and yet another drafts a response.Your online order arrives damaged, so you request a refund.

Young people in low- and middle-income countries appear generally more optimistic about how AI can enhance their work prospects and social lives than their Western peers, according to our new survey of people in 10 countries in Africa and South Asia.Young people in low- and middle-income countries appear generally more optimistic about how AI can enhance their work prospects and social lives than their Western peers, according to our new survey of people in 10 countries in Africa and South Asia.Machine learning & AI[#item_full_content]
Artificial intelligence (AI) can identify people by the way they walk. The technology focuses on how a person’s joints move, rather than on body shape alone, and could improve long-distance identity verification for security and law enforcement.Artificial intelligence (AI) can identify people by the way they walk.

Walking robots, such as quadruped robotic dogs, must be able to move safely through rough, often changing environments. Today, there are two main ways to program these walking, or legged, robots. The first is called model predictive control. This technique optimizes the robot’s behavior but relies on accurate dynamics models, which are challenging to achieve in real-world settings and often require simplifying assumptions. The second is model-free reinforcement learning, which allows the robot to learn reliable but fixed behaviors, making them difficult to adapt after training.Walking robots, such as quadruped robotic dogs, must be able to move safely through rough, often changing environments.

Recent technological advances have opened valuable possibilities for supporting people with motor impairments or who are recovering from injuries to the brain, spinal cord or nerves. Millions of people worldwide currently experience difficulty moving their hands or other parts of their body. Some of these motor impairments are associated with progressive neurodegenerative diseases, such as amyotrophic lateral sclerosis (ALS), while others are the result of neurological damage caused by an injury or a stroke.Recent technological advances have opened valuable possibilities for supporting people with motor impairments or who are recovering from injuries to the brain, spinal cord or nerves.

Soft grippers, which are built from flexible materials that can bend and deform, are attracting a lot of attention from robotics researchers worldwide. Unlike conventional robots made from rigid metal or plastic, soft grippers can grasp items more gently while naturally adapting to different shapes. This makes them uniquely suitable for delicate tasks such as handling fruit, baked goods, lab samples and medical supplies.Soft grippers, which are built from flexible materials that can bend and deform, are attracting a lot of attention from robotics researchers worldwide.

More and more people are turning to AI when they feel stressed or worried. Researchers at Leiden University studied how and why people use chatbots for emotional support. Their conclusion: AI meets a real need, but also raises serious concerns.More and more people are turning to AI when they feel stressed or worried.

An AI flaw that can be found today in one model could be quietly replicated across dozens of products and services built on the same underlying technology. Until now, the AI community has lacked a formal pathway to report those flaws, alert affected vendors and coordinate a response. Researchers at Carnegie Mellon University’s Software Engineering Institute (SEI), alongside collaborators from academia and industry, helped build one. Flaw Reporting for AI (FLARE-AI) is a new open-source platform that lets anyone report an AI vulnerability and route it to developers, vendors and government agencies equipped to act.An AI flaw that can be found today in one model could be quietly replicated across dozens of products and services built on the same underlying technology.
