« A comprehensive description, with code samples, of what happen when -ffast-math is enabled with GCC. »

« Even wonder why NumPy is so fast ? It is because it uses an optimized BLAS (Basic Linear Algebra Subprograms). Starting with a naive implementation, and optimizing step by step, this article gives insight about how we could achieve similar performances with plain C++. »

« From Wikipedia: "Images of the Mandelbrot set exhibit an elaborate and infinitely complicated boundary that reveals progressively ever-finer recursive detail at increasing magnifications; mathematically, one would say that the boundary of the Mandelbrot set is a fractal curve. The "style" of this recursive detail depends on the region of the set boundary being examined." This purely in-browser application (with JavaScript Web Workers) let you explore this mesmerizing fractal. You can zoom in any region many times. For an optimum experience you could read the instructions. »

« Based on AlphaZero, Alpha Tensor as quoted from the article is "the first artificial intelligence (AI) system for discovering novel, efficient, and provably correct algorithms for fundamental tasks such as matrix multiplication". Deepmind published its discoveries last week in Nature. »

« Kalman filters are algorithms used intensively in various domain, such as navigation, guidance and control. It was, for example, incorporated in Apollo navigation computer. Understanding Kalman filters is not obvious, though, as it could be seen in Wikipedia's definition. This article tries to explain the 'simple' Kalman Filter in the context of autonomous vehicle's navigation and gives some practical insights. It points also to two other well detailed articles about Extended Kalman Filters and Unscented Kalman Filters. »

« Monday was the 'Pi Day' (3/14), and NASA celebrated this event with its ninth Pi Day Challenge. Illustrated answers are also now available on the same link. »

« If you are interested in 3D and have a little background in C++, this online book and tutorial is for you. »

« L'Université des Grisons en Suisse a battu le record, précédemment détenu par Google, de calcul du nombre Pi avec 62 800 milliards de décimales après la virgule, et tout ça en un peu plus de 108 jours. »

« Ce livre, en cours de rédaction, se propose de fournir les outils mathématiques indispensables pour aborder les techniques courantes d'apprentissage machine (machine learning). »

« Ce week end sur la Place Saint-Sulpice à Paris se tiendra le Salon Culture et Jeux Mathématiques 2016. Le thème du salon sera l'impact socio-économique des mathématiques dans notre vie quotidienne. De nombreux stands sont prévus selon votre âge (à partir de 5 ans) et vos centres d'intérêts (des stands d’animation de culture et de jeux mathématiques, des Conférences-rencontres et débats scienfifiques, des spectacles). »
