The kernel of a domain is the (convex) set of locations from which you can see all other locations in the domain. It is the intersections of all half-planes tangent to the shape. en.wikipedia.org/wiki/Star-shap…

The co-area formula relates the total variation to the perimeters of the level set. Can be extended to (possibly) discontinuous functions of bounded total variation. en.wikipedia.org/wiki/Coarea_fo…

The heat equation can be applied to diffuse probability densities (in particular, maintains positivity and unit mass). Its solution is obtained as the convolution of the initial condition with a Gaussian. en.wikipedia.org/wiki/Heat_equa…

The binomial law is a sum of Bernoulli 0/1 random variables. After rescaling, converge to a Gaussian for a large number of variables (a particular case of the central limit theorem). en.wikipedia.org/wiki/Binomial_…

The convex hull is the smallest enclosing convex set. It is also the intersection of all half-spaces containing the points, and the set of all possible convex combinations. en.wikipedia.org/wiki/Convex_hu…

Florida Gov. Ron DeSantis (R) signed a bill into law Monday barring the state’s colleges and universities from spending money on diversity, equity and inclusion programs, and limiting how race can be discussed in many courses. “If you look at the way this has actually been

Beginner or Advanced R User? 🤔 ➡️ This cheat sheet is gold. It summarizes all the best practices R developers should apply. If some of it isn’t familiar, the first module of my productive-r-workflow.com project explains exactly this! Thanks so much Jacob Scott 🙏 What's missing?

Flow Matching aims to learn a "flow" that transforms a simple source distribution (e.g. Gaussian) to an arbitrarily complex target distribution. This video shows the evolution of the marginal probability path as a source distribution is transformed to a target distribution.
