A team of Australian researchers has designed a reliable strategy for testing physical abilities of humanoid robots. Using a blend of machine learning methods and algorithms, the research team succeeded in enabling test robots to effectively react to unknown changes in the simulated environment, improving their odds of functioning in the real world. The findings have promising implications in the broad use of humanoid robots in fields such as healthcare, education, disaster response and entertainment.
MIT researchers have developed a battery-free underwater communication system that uses near-zero power to transmit sensor data. The system could be used to monitor sea temperatures to study climate change and track marine life over long periods -- and even sample waters on distant planets. They are presenting the system at the SIGCOMM conference this week, in a paper that has won the conference's 'best paper' award.
Newly discovered properties in the compound uranium ditelluride show that it could prove highly resistant to one of the nemeses of quantum computer development -- the difficulty with making such a computer's memory storage switches, called qubits, function long enough to finish a computation before losing the delicate physical relationship that allows them to operate as a group. This relationship, called quantum coherence, is hard to maintain because of disturbances from the surrounding world.
A new paper in Advanced Photonics, an open-access journal co-published by SPIE, the international society for optics and photonics, and Chinese Laser Press (CLP), demonstrates distinct improvements to the inference and generalization performance of diffractive optical neural networks.
Robots need to know the reason why they are doing a job if they are to effectively and safely work alongside people in the near future. In simple terms, this means machines need to understand motive the way humans do, and not just perform tasks blindly, without context.
It has long been known that gold can be used to do things that philosophers have never even dreamed of. The Institute of Nuclear Physics of the Polish Academy of Sciences in Cracow has confirmed the existence of 'gold glue': bonds involving gold atoms, capable of permanently bonding protein rings. Skilfully used by an international team of scientists, the bonds have made it possible to construct molecular nanocages with a structure so far unparalleled in nature or even in mathematics.
Researchers from the University of Maryland have figured out how to reliably create questions that challenge computers and reflect the complexity of human language through a human-computer collaboration, developing a dataset of more than 1,200 questions that, while easy for people to answer, stump the best computer answering systems today. The system that learns to master these questions will have a better understanding of language than any system currently in existence.
Nothing disappoints quite like a good story with a lousy finish. So researchers at Carnegie Mellon University who work in the young field of automated storytelling don't think they're getting ahead of themselves by devising better endings.
A new study led by a Berkeley Lab physicist details how a quantum computing technique called 'quantum annealing' can be used to solve problems relevant to fundamental questions in nuclear physics about the subatomic building blocks of all matter. It could also help answer other vexing questions in science and industry, too.
Japanese researchers were able to rapidly and accurately predict the microstructure of Nickel -- Aluminum (Ni-Al) alloys that are commonly used in the design of jet engine turbine parts. Predictions of the microstructure of these alloys have so far been time-consuming and expensive. The findings have the potential to greatly advance the design of materials -- made up of a range of different alloys -- that are used to make products in several different industry sectors.
