    DeepMind achieves Giant Leap in Sorting Speed

    June 13, 2023, Categories  Physics, Technology/Electronics

    Fundamentally different algorithms discovered by AlphaDev. a, A flow diagram of the variable sort 4 (VarSort4) human benchmark algorithm. In this algorithm, a sequence of unsorted numbers are input into the algorithm. If the sequence length is four, three or two numbers, then the corresponding sort 4, sort 3 or sort 2 sorting network is called that sorts the resulting sequence. The result is then returned and output by the function. b, The VarSort4 algorithm discovered by AlphaDev. This algorithm also receives sequences of length four, three or two numbers as input. In this case, if the length is two, then it calls the sort 2 sorting network and returns. If the length is three then it calls sort 3 to sort the first three numbers and returns...

    Researchers use AI to discover New Planet outside Solar System

    The exoplanet was detected using machine learning, a branch of artificial intelligence

    A University of Georgia research team has confirmed evidence of a previously unknown planet outside of our solar system, and they used machine learning tools to detect it.

    A recent study by the team showed that machine learning can correctly determine if an exoplanet is present by looking in protoplanetary disks, the gas around newly formed stars.

    The newly published findings represent a first step toward using machine learning to identify previously overlooked exoplanets.

    “We confirmed the planet using traditional techniques, but our models directed us to run those simulations and showed us exactly where the planet might be,” said Jason Terry, doctoral student in the UGA Franklin Colleg...

    AlphaFault: High schoolers give Fabled AI a Problem it Can’t Crack

    A bioinformatics boot camp for high schoolers at Skoltech turned into a venue for the latest chapter in the ongoing contest between humans and artificial intelligence in science. Having earlier resolved a key 50-year-old problem of structural bioinformatics, the breakthrough AI program AlphaFold proved inapplicable to another challenge researchers in this field are faced with.

    This finding is reported in a PLOS ONE study, whose authors refute the claims by some AlphaFold enthusiasts that DeepMind’s AI has mastered the ultimate protein physics and is the be-all and end-all of structural bioinformatics.

    Structural bioinfor...

    Artificial Intelligence discovers Secret Equation for ‘Weighing’ Galaxy Clusters

    March 28, 2023, Categories  Physics, Astronomy/Space

    Astrophysicists at the Institute for Advanced Study, the Flatiron Institute and their colleagues have leveraged artificial intelligence to uncover a better way to estimate the mass of colossal clusters of galaxies. The AI discovered that by just adding a simple term to an existing equation, scientists can produce far better mass estimates than they previously had.

    The improved estimates will enable scientists to calculate the fundamental properties of the universe more accurately, the astrophysicists reported March 17, 2023, in the Proceedings of the National Academy of Sciences.

    “It’s such a simple thing; that’s the beauty of this,” says study co-author Francisco Villaescusa-Navarro, a research scientist at the Flatiron Institute’s Center for Computational Astrophysics (CCA) in...
