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:  programming

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?

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. Toolchain management with rustup Rust is installed and managed by the rustup tool. Rust has a 6-week rapid release process and supports a great number of platforms, so there are many builds of Rust available at any time. rustup manages these builds in a consistent way on every platform that Rust supports, enabling installation of Rust from the beta and nightly release channels as well as support for additional cross-compilation targets. 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

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

DeepMind AI One-Ups Mathematicians at a Calculation Crucial to Computing DeepMind has done it again. After solving a fundamental challenge in biology—predicting protein structure—and untangling the mathematics of knot theory, it’s taken aim at a fundamental computing process embedded inside thousands of everyday applications. From parsing images to modeling weather or even probing the inner workings of artificial neural networks, the AI could theoretically speed up calculations across a range of fields, increasing efficiency while cutting energy use and costs. But more impressive is how they did it. “Algorithms have been used throughout the world’s civilizations to perform fundamental operations for thousands of years,” wrote co-authors Drs. AlphaTensor blazes a trail to a new world where AI designs programs that outperform anything humans engineer, while simultaneously improving its own machine “brain.” Enter the Matrix Multiplication The problem AlphaTensor confronts is matrix multiplication. But what if there are even more efficient methods?
