L'agriculture croît dans les mathématiques Réduction des pesticides et engrais, prédiction des récoltes, adaptation au changement climatique... Les défis posés à l’agriculture sont multiples et les mathématiciens ont des solutions à apporter. Focus sur leurs travaux à l'occasion du Salon de l'agriculture qui se tient à la Porte de Versailles jusqu'au 3 mars. Peut-on mettre l’agriculture en équations ? Simulation de la croissance de plantes (betterave, Arabidopsis, blé, riz, maïs, tournesol, chrysanthème, concombre, tomate, poivron, caféier, pin) par le logiciel Digiplante du laboratoire de mathématiques et informatique de CentraleSupélec. Prédire la récolte grâce aux modèles Les semenciers qui mettent au point de nouvelles variétés tirent aussi un vrai bénéfice de ces modélisations, qui leur permettent d’optimiser leurs essais : sur cent essais d’une nouvelle variété réalisés en différents endroits de la planète, 20 seront effectivement conduits en conditions de culture, et le reste sera effectué par simulation.
Adidas and Stella McCartney launch new line to promote eco-friendly fashion - Climate Action Programme Adidas has revealed a new clothing line with Stella McCartney which aims to focus on the importance of protecting nature. In keeping with Adidas’s pledge to increase sustainability, the new AW18 line will include eco-friendly fabrics such as recycled polyester, organic cotton, and recycled ocean plastic. Stella McCartney said: “More than half of our apparel and a third of our footwear in AW18 are made with eco-innovative and recycled materials.” The line is designed to allow female athletes to exercise in any weather conditions. The clothing pieces will feature nature-inspired prints which act as a reminder to look after the world we live in. In addition, last week, Ms McCartney unveiled the new sustainably designed ‘Loop Sneakers’ on her Instagram page, which are also recyclable. Ming Xi, supermodel and global ambassador of Adidas by Stella McCartney, revealed “I am really inspired by the brands ambition to make a difference and its devotion to sustainability.”
Strawberry Perl for Windows Deep Learning Is Going to Teach Us All the Lesson of Our Lives: Jobs Are for Machines — Basic income Deep Learning Is Going to Teach Us All the Lesson of Our Lives: Jobs Are for Machines (An alternate version of this article was originally published in the Boston Globe) On December 2nd, 1942, a team of scientists led by Enrico Fermi came back from lunch and watched as humanity created the first self-sustaining nuclear reaction inside a pile of bricks and wood underneath a football field at the University of Chicago. Known to history as Chicago Pile-1, it was celebrated in silence with a single bottle of Chianti, for those who were there understood exactly what it meant for humankind, without any need for words. Now, something new has occurred that, again, quietly changed the world forever. The language is a new class of machine learning known as deep learning, and the “whispered word” was a computer’s use of it to seemingly out of nowhere defeat three-time European Go champion Fan Hui, not once but five times in a row without defeat. What actually ended up happening when they faced off?
Maimosine met le monde en modèles De l’exercice physique à la surchauffe des microprocesseurs, les mathématiciens de Maimosine, centre de modélisation et de simulation numérique, aident les chercheurs et industriels du bassin grenoblois à mieux comprendre certains phénomènes complexes. Le point commun entre un coureur en plein effort, une pièce qui vibre dans un moteur, de la glace de mer en train de se fragmenter ou des microprocesseurs qui surchauffent ? Ce sont tous des sujets d’étude pour les mathématiciens de la Maison de la modélisation et de la simulation, nanosciences et environnement (Maimosine). Créée à Grenoble en 2010 et juchée sur les hauteurs d’une tour dominant le campus universitaire, elle constitue un refuge pour les chercheurs et entreprises de la région lorsqu’un phénomène complexe leur échappe. « Modéliser, c’est mettre en équations un phénomène, le simplifier. Optimiser l’effort physique V. Un des camps de l'expédition Damodar au Népal. Localiser un phénomène de vibration Le but ? À lire aussi :
Vegan Designer Stella McCartney Edges Out Chanel and Louis Vuitton as Kindest Luxury Fashion Brand Vegan fashion brand Stella McCartney has been ranked number one in empathy, generosity, and kindness on the New York-based Luxury Institute’s annual “Emotionally Intelligent Brand Index.” McCartney, daughter of former Beatle Sir Paul McCartney and the late musician and entrepreneur Linda McCartney, edged out leading luxury brands including Chanel and Louis Vuitton in earning the top spot in those categories. The Luxury Institute’s ranking looks at how a brand relates to its customers, employees, and society at large, including its impact on the environment. Millennial Market “Today affluent consumers across all generations, but especially Millennials, think of brands as organic, living entities comprised of the purpose, values and behaviors of the people who lead them and who represent them at the front lines, across any channel,” says Milton Pedraza, CEO of the Luxury Institute. “A brand, today, is known well beyond its products.

Install Rust - Rust Programming Language Getting started If you're just getting started with Rust and would like a more detailed walk-through, see our getting started page. Windows considerations On Windows, Rust additionally requires the C++ build tools for Visual Studio 2013 or later. The easiest way to acquire the build tools is by installing Microsoft Visual C++ Build Tools 2019 which provides just the Visual C++ build tools. For further information about configuring Rust on Windows see the Windows-specific rustup documentation. Toolchain management with rustup Rust is installed and managed by the rustup tool. If you've installed rustup in the past, you can update your installation by running rustup update. For more information see the rustup documentation. Configuring the PATH environment variable In the Rust development environment, all tools are installed to the ~/.cargo/bin %USERPROFILE%\.cargo\bin directory, and this is where you will find the Rust toolchain, including rustc, cargo, and rustup.
Researchers find that large language models struggle with math Join Transform 2021 this July 12-16. Register for the AI event of the year. Mathematics is the foundation of countless sciences, allowing us to model things like planetary orbits, atomic motion, signal frequencies, protein folding, and more. Moreover, it’s a valuable testbed for the ability to problem solve, because it requires problem solvers to analyze a challenge, pick out good methods, and chain them together to produce an answer. It’s revealing, then, that as sophisticated as machine learning models are today, even state-of-the-art models struggle to answer the bulk of math problems correctly. A new study published by researchers at the University of California, Berkeley finds that large language models including OpenAI’s GPT-3 can only complete 2.9% to 6.9% of problems from a dataset of over 12,500. Prior research has demonstrated the usefulness of AI that has a firm grasp of mathematical concepts. Image Credit: MATH VentureBeat
