Visualizing Algorithms

Visualizing Algorithms
The power of the unaided mind is highly overrated… The real powers come from devising external aids that enhance cognitive abilities. —Donald Norman Algorithms are a fascinating use case for visualization. To visualize an algorithm, we don’t merely fit data to a chart; there is no primary dataset. But algorithms are also a reminder that visualization is more than a tool for finding patterns in data. #Sampling Before I can explain the first algorithm, I first need to explain the problem it addresses. Light — electromagnetic radiation — the light emanating from this screen, traveling through the air, focused by your lens and projected onto the retina — is a continuous signal. This reduction process is called sampling, and it is essential to vision. Sampling is made difficult by competing goals. Unfortunately, creating a Poisson-disc distribution is hard. You can see from these dots that best-candidate sampling produces a pleasing random distribution. Here’s how it works: Now here’s the code: Related:  Modélisationprogramming

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.

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 :

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

Modéliser plus pour simuler moins À l’occasion du colloque « Modélisation : succès et limites », le chercheur Frédéric Alexandre nous éclaire sur les développements actuels de la simulation et de la modélisation. Frédéric Alexandre, vous êtes chercheur au Laboratoire bordelais de recherche en informatique (LaBRI1) et intervenant du colloque « Modélisation : succès et limites » qui se tient le 6 décembre 2016. Qu’entend-on au juste aujourd'hui par modélisation et simulation ? Visualisation issue de la simulation numérique des impacts de gouttelettes sur une surface liquide. En quoi cette démarche de modélisation-simulation a-t-elle bouleversé la façon de faire de la recherche dans certaines disciplines ? Ces quinze dernières années, les progrès des algorithmes ont autant contribué à l'accélération des calculs que la puissance des processeurs. On nous annonce depuis longtemps la fin de la loi de Moore relative à l'accroissement régulier de la puissance des ordinateurs.

Other Installation Methods · The Rust Programming Language Which installer should you use? Rust runs on many platforms, and there are many ways to install Rust. If you want to install Rust in the most straightforward, recommended way, then follow the instructions on the main installation page. That page describes installation via rustup, a tool that manages multiple Rust toolchains in a consistent way across all platforms Rust supports. Why might one not want to install using those instructions? Offline installation. rustup downloads components from the internet on demand. Rust’s platform support is defined in three tiers, which correspond closely with the installation methods available: in general, the Rust project provides binary builds for all tier 1 and tier 2 platforms, and they are all installable via rustup. Other ways to install rustup The way to install rustup differs by platform: On Unix, run curl -sSf | sh in your shell. curl -sSf | sh -s -- --help Standalone installers
