Some 45 million moviegoers were mesmerized by the special effects of "The Wizard of Oz" when it hit theaters in 1939. The magical scenes in Emerald City were the first to film actors in front of a green screen that later would be replaced with footage of fantastical scenes recorded at a different time and place. https://techxplore.com/news/2023-07-netflix-magenta-approach-green-screen.html Computer Sciences Mon, 10 Jul 2023 12:30:01 EDT news608210848 Setting its sights on evolving graphics processing units in a growing universe of generative AI, Intel announced the release of several papers outlining efforts it is pursuing in what observers say is a multibillion-dollar opportunity in coming years for the semiconductor chip giant. https://techxplore.com/news/2023-07-intel-high-rendering-graphics-low-power-gpus.html Computer Sciences Mon, 10 Jul 2023 10:30:01 EDT news608203501 Reservoir computing is a promising computational framework based on recurrent neural networks (RNNs), which essentially maps input data onto a high-dimensional computational space, keeping some parameters of artificial neural networks (ANNs) fixed while updating others.

The famed astronomer took on this problem when asked how to stack cannonballs so as to take up the least amount of space. Kepler concluded that the best configuration is a so-called face-centered cubic lattice—an approach commonly used in grocery stores for displaying oranges: Every cannonball should rest in the cavity left by the four cannonballs (lined up in a tight, two-by-two square) lying directly below it. This was merely a conjecture, however, that was not proven until almost 400 years later by a University of Michigan mathematician. https://techxplore.com/news/2023-07-method-dense-placement-rigid.html Computer Sciences Thu, 06 Jul 2023 14:24:01 EDT news607872234 New research from the University of Montana and its partners suggests artificial intelligence can match the top 1% of human thinkers on a standard test for creativity. https://techxplore.com/news/2023-07-ai-creative.html Computer Sciences Wed, 05 Jul 2023 15:40:02 EDT news607790397 In a new study, researchers from Université libre de Bruxelles demonstrate the potential of blockchain technology, known from cryptocurrencies such as Bitcoin and Ethereum, to secure the coordination of robot swarms.
