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.

One of the simplest algorithms for sampling from a probability distribution is Random Walk Metropolis-Hastings. It proposes new samples by taking Gaussian-distributed steps, accepting or rejecting them to maintain the target distribution. I call this pdf the "fidget spinner".

A basic strategy for drawing from a random distribution is to first generate uniformly-distributed points, then "warp" these points so they're spread out according to the target distribution. For example, the Box-Muller transform takes uniform points to normally-distributed ones

One common trick in MCMC methods is called 'burn-in'. It allows you to produce better samples by letting the chain first converge to the target distribution, discarding the first few samples which may be out of distribution.

Langevin Monte Carlo allows you to draw samples from a probability distribution using its log gradient ∇ log p(x). By performing a sort of gradient ascent with noise you can navigate around the distribution. Langevin MC is heavily related to modern diffusion models.

It’s really simple: capitalism is the uneven distribution of wealth; socialism is the even distribution of poverty. Always, no exceptions. Why do so many people still believe in a socialist utopia?

Hamiltonian Monte Carlo frames sampling from a probability distribution as a physics problem. By endowing "particles" with momentum and simulating their energy and motion through Hamilton's equations you can efficiently explore a distribution.

This is a fun interactive article explaining the intuition behind Gaussian Processes. Gaussian Processes allow you to construct a distribution over functions with a continuous domain. They are incredibly useful for applications like Bayesian regression.

In aeronautics, a spoiler (sometimes called a lift spoiler) is a device which intentionally reduces the lift component of an airfoil in a controlled way. Most often, spoilers are plates on the top surface of a wing that can be extended upward into the airflow to spoil the streamline flow. By so doing, the spoiler creates a controlled stall over the portion of the wing behind it, greatly reducing the lift of that wing section. Spoilers differ from airbrakes in that airbrakes are designed to increase drag without disrupting the lift distribution across the wing span, while spoilers disrupt the lift distribution as well as increasing drag.

A source at one of the Gaza distribution sites tells me that Hamas set up a roadblock to prevent Gazans from getting aid. They broke through it and were shouting “thank you America” upon reaching the site.

Horrible: This video shows thousands of Palestinians running after an Israeli tank, as its withdrawal signals the start of U.S. aid distribution following a one-hour security sweep. The soldier who released the footage compared the scene to “The Walking Dead.”

Instead of pointing lookAt to a position, I tried driving it along a line. The control over distribution is kind of nice.

THE BITCOIN MANIPULATION PHASE IS OVER. DISTRIBUTION IS NEXT. Accumulate quietly. Shake out retail. Then distribute. Accumulation: complete. Manipulation: complete. Distribution: $105K–$220K target. $77K is the line between phases. Hold it: distribution begins. Final leg up. Lose it: manipulation wasn't finished. They always need your coins before the move. Most people give them up right here.

Our analysis of Israel’s so-called ‘humanitarian bubbles’ indicates that this new system of aid distribution is simply an extension of the existing architecture of spatial control. The routes established for civilian access to these aid distribution centres (in blue) are continuous with Israeli military raid routes (in red), forming a militarised network designed to facilitate forced displacement and population control.

EXCLUSIVE: Video of Gazans shouting "Thank you, America!" at a Gaza Humanitarian Foundation (GHF) distribution center today. My source tells me some Gazans said this was the first time they’ve received humanitarian aid without having to pay for it.

Gazans rush for aid at an American-run food distribution center. No aid for months, and when bits of aid are allowed in, its a show for Israelis to enjoy, or an opportunity for Israeli target practice.
