    Albert Einstein once said, “You have to learn the rules of the game, and then you have to play better than anyone else.” That could well be the motto at DeepMind, as a new report reveals it has developed a program that can master complex games without even knowing the rules.

    DeepMind, a subsidiary of Alphabet, has previously made groundbreaking strides using reinforcement learning to teach programs to master the Chinese boardgame Go and the Japanese strategy game Shogi, as well as chess and challenging Atari video games. In all those instances, computers were given the rules of the game.

    But Nature reported today that DeepMind’s MuZero has accomplished the same feats—and in some instances, beat the earlier programs—without first learning the rul...

    1. (a) Cross-sectional diagram of the photosensitive capacitor employed as a retinomorphic sensor. Au is gold, Perovskite is methylammonium lead iodide (MAPbI3), SiO2 is silicon dioxide, and Si++ is highly doped (conducting) silicon. (b) Circuit diagram of the measurement setup. (c) Optical power density (P
    P) incident on the sensor as a function of time. (d) Experimentally measured VR
    R as a function of time.

    Researchers at Oregon State University are making key advances with a new type of optical sensor that more closely mimics the human eye’s ability to perceive changes in its visual field.

    The sensor is a major breakthrough for fields such as image recognition, robotics and artificial intelligence...

    AI used to show how Hydrogen becomes a Metal inside Giant Planets

    September 11, 2020, Categories  Uncategorized

    Bingqing Cheng et al. ‘Evidence for supercritical behaviour of high-pressure liquid hydrogen.’ Nature (2020). DOI: 10.1038/s41586-020-2677-y.

    Dense metallic hydrogen – a phase of hydrogen which behaves like an electrical conductor – makes up the interior of giant planets, but it is difficult to study and poorly understood. By combining artificial intelligence and quantum mechanics, researchers have found how hydrogen becomes a metal under the extreme pressure conditions of these planets.

    The researchers, from the University of Cambridge, IBM Research and EPFL, used machine learning to mimic the interactions between hydrogen atoms in order to overcome the size and timescale limitations of even the most powerful supercomputers...

    Drones can now Scan Terrain and Excavations without Human Intervention

    March 12, 2020, Categories  Physics, Technology/Electronics

    Measuring and documenting gravel and limestone quarries, cliff faces and similar natural and man-made formations is often done using drones that photograph the area. New research may make the pilots superfluous. (NB: The vertical rod on top of the drone carries a wind detector for test purposes, and it is not present on the final version of the drone.)

    Drone pilots may become superfluous in the future. New research from Aarhus University has allowed artificial intelligence to take over control of drones scanning and measuring terrain.

    A research project at Aarhus University (AU) in collaboration with the Technical University of Denmark (DTU) aims to make measuring and documenting gravel and limestone quarries much faster, cheaper and easier in the future.
