Machine learning happens a lot like erosion. Data is hurled at a mathematical model like grains of sand skittering across a rocky landscape. Some of those grains simply sail along with little or no impact. But some of them make their mark: testing, hardening, and ultimately reshaping the landscape according to inherent patterns and fluctuations […]
A team of scientists at the Max Planck Institute for Intelligent Systems and the University of California, Irvine constructed a robot leg that, like its natural model, is very energy efficient. BirdBot benefits from a foot-leg coupling through a network of muscles and tendons that extends across multiple joints. In this way, BirdBot needs fewer […]
A new risk analysis, published today in the journal Nature Machine Intelligence, warns that the future use of artificial intelligence in agriculture comes with substantial potential risks for farms, farmers and food security that are poorly understood and under-appreciated. “The idea of intelligent machines running farms is not science fiction. Large companies are already pioneering the next […]
Xu and colleagues report on laboratory tests in which they employed an array of commercially available solar cells to develop an optimal lens-free system for high-speed optical detection underwater in the Optica Publishing Group journal Optics Letters. Photodiodes, which have traditionally been utilized as detectors in wireless optical communication, have a much smaller detecting area […]
A University of Bristol team has created a new driving system for flapping-wing autonomous robots, which uses an electromechanical zipping mechanism that eliminates the need for conventional motors and gears. This new advance, published today in the journal Science Robotics, could pave the way for smaller, lighter and more effective micro flying robots for environmental monitoring, […]
Researchers have developed a new technique, called MonoCon, that improves the ability of artificial intelligence (AI) programs to identify three-dimensional (3D) objects, and how those objects relate to each other in space, using two-dimensional (2D) images. For example, the work would help the AI used in autonomous vehicles navigate in relation to other vehicles using […]
Warnings have emerged about the unreliability of the metrics used to detect whether an audio perturbation designed to fool AI models can be perceived by humans Researchers at the UPV/EHU-University of the Basque Country show that the distortion metrics used to detect intentional perturbations in audio signals are not a reliable measure of human perception, […]
Two Ruhr-Universität Bochum (RUB) researchers have proposed a novel theory of consciousness.They’ve been studying the nature of consciousness for a long time, as well as how and where consciousness is generated in the brain and if animals have consciousness.Consciousness, according to the new notion, is a state that is linked to sophisticated cognitive functions, rather […]
“You’ll see robotic hands do a power grasp and a precision grasp and then kind of imply that they can do everything in between,” said Wilson Ruotolo, PhD ’21, a former graduate student in the Biomimetics and Dextrous Manipulation Lab at Stanford University. “What we wanted to address is how to create manipulators that are […]
