CRAN Task View: Optimization and Mathematical Programming
This CRAN Task View contains a list of packages that offer facilities for solving optimization problems. Although every regression model in statistics solves an optimization problem, they are not part of this view. If you are looking for regression methods, the following views will also contain useful starting points: MachineLearning, Econometrics, Robust Packages are categorized according to the following sections. See also the “Related Links” and “Other Resources” sections at the end.

Mathematical models reveal a 'hidden order' in dryland vegetation worldwide
If you've ever traveled through drylands, you may have noticed striking vegetation patterns—stripes, spots, or rings—scattered across otherwise barren landscapes. From "tiger bush" in West Africa to the enigmatic "fairy circles" of Namibia, these patterns have long inspired wonder and scientific curiosity.

Nossa, que alívio, jš não estava aguentando. Estava desde o ano passado sem fazer nenhum toot! 😀

Wie jedes Mathematiky bestätigen kann, ist Normal einfach die Richtung, die von der jeweiligen Ebene, um die es geht, zu allen Seiten gleich weit entfernt ist. Wir nennen das auch orthogonal.
Normal ist folglich maximal anders.

Median2Median: Zero-shot Suppression of Structured Noise in Images
Image denoising is a fundamental problem in computer vision and medical imaging. However, real-world images are often degraded by structured noise with strong anisotropic correlations that existing methods struggle to remove. Most data-driven approaches rely on large datasets with high-quality labels and still suffer from limited generalizability, whereas existing zero-shot methods avoid this limitation but remain effective only for independent and identically distributed (i.i.d.) noise. To add…

Comment des partenaires de Pierre-Edouard Stérin mettent le milliardaire à distance : « Il est devenu radioactif »
Les engagements politiques à l’extrême droite de l’entrepreneur et de son numéro deux, François Durvye, conseiller du Rassemblement national, commencent à ternir l’image du groupe, en proie à des difficultés financières.

Si on ne change rien, 79 % des glaciers mondiaux auront disparu d'ici 2100, mettant en péril l'approvisionnement en eau de 2 milliards de personnes et provoquant une élévation spectaculaire du niveau des mers.
