The probing-class demo board is (I think) finished and awaiting final design review.
Anyone else want to throw a few eyes on it before it goes out to JLC?

Mysterious strikes targeting multiple Ecuadorian fishing boats near the Galšpagos Islands this year were carried out as part of a covert CIA program.
According to the WaPo, citing a source with knowledge,
“the strikes were part of a ‘covert action’ program, a type of secret operation overseas that is approved by the president but where the role of the U.S. government is not publicly acknowledged.”
With the Pentagon denying any knowledge of or involvement with the strikes on …

Abstract: In this article we consider bridging between two mixture probability measures. In particular, given access to a Markov kernel between two component distributions, we provide a general mechanism to generate samples from one mixture to the other. Associated to a given reference and extended state space, we prove entropic optimality of this approach. In order to use this idea one needs to know the underlying mixtures and the Markov kernel, which is seldom available, and so we consider the case of Gaussian mixtures and Schr\"odinger Bridges. We prove a general $2-$Wasserstein continuity bound between the exact bridge and one that is approximated, based on $\epsilon-$covariance inflation, and these rely on a novel continuity analysis of perturbed Riccati maps. We apply our results in the context of bridging mixtures of Gaussians, single Gaussians and empirical estimators of the Gaussian parameters and the Monge map. For mixtures of Gaussians, when the parameters are estimated using the Expectation-Maxmization algorithm, the upper-bound on the $2-$Wasserstein distance between the true and approximated bridges is, under assumptions and with probability at least $1-10N^{-1}$, $\mathcal{O}\big(\big[\big(\tfrac{d\log N}{N}\big)^{1/2}\left\{1 \big(\tfrac{d\log N}{N}\right)^{1/2}(\epsilon^{-2} 1)\big\} \epsilon^2\big]\big) $
and for the other two cases, in expectation, $\mathcal{O}\left(d\left\{\tfrac{1 \epsilon^{-2}}{1 N} \epsilon^2\right\}\right)$, where $d,N\in\mathbb{N}$ is the dimension of the Gaussian and the number of empirical samples respectively. We also investigate our bounds numerically.

Amazon found a way to not be held accountable for any terrible thing they've done to you.
Making sure that a judge or a jury of your peers won't enter into it seems like a ploy by a company about to really screw us
