Last-Iterate Complexity of SGD for Convex and Smooth Stochastic Problems
Most results on Stochastic Gradient Descent (SGD) in the convex and smooth setting are presented under the form of bounds on the ergodic function value gap. It is an open question whether bounds can be derived directly on the last iterate of SGD in this context. Recent advances suggest that it should be possible. For instance, it can be achieved by making the additional, yet unverifiable, assumption that the variance of the stochastic gradients is uniformly bounded. In this paper, we show that …

Stochastic Integration on Stochastic Sets of Interval Type and Applications to Mathematical Finance
In the existing works, stochastic sets $\mathbb{B}$ of interval type, along with $\mathbb{B}$-stochastic processes, were introduced within the framework of stochastic analysis. In this paper, we undertake the construction of $\mathbb{B}$-stochastic integration by exploring three novel types of $\mathbb{B}$-stochastic integrals: Stieltjes integrals of $\mathbb{B}$-predictable processes with respect to $\mathbb{B}$-adapted processes with finite variation, stochastic integrals of $\mathbb{B}$-pred…

“Obama’s Prophetic Voice Has Never Been More Needed
Dare we hope for audacity?
As various leaders call for resistance against Trump’s march to dictatorship, one prophetic voice has been missing in action. Barack Obama, before he was president, was a professor of constitutional law. He understands the stakes better than anyone. He also knows how to give a powerful and inspiring speech….”

It'll probably not be fully mounted in the rack for a while (just either laying on top of the rack or on top of some other switches) but at least I can finally stop using my CCR2004 for LAN duties.

China wants foreign businesses to invest more in the country -- but recent actions taken against foreign executives are sending a chill.
⭐️Chinese authorities have blocked a U.S.-based Wells Fargo banker from returning home,
⭐️and separately sentenced a Japanese executive to more than three years’ imprisonment for espionage.
Though few details of the cases have been made known, they are a reminder of China’s expansive security apparatus
and what to some executives, bu…

Efficient Online Mirror Descent Stochastic Approximation for Multi-Stage Stochastic Programming
We study the unconstrained and the minimax saddle point variants of the convex multi-stage stochastic programming problem, where consecutive decisions are coupled through the objective functions, rather than through the constraints. Based on the analysis of deterministic mirror descent algorithms with inexact gradients, we introduce the idea of \textit{stochastic conditional gradient oracles}, a multi-stage analog of the stochastic gradient oracles used in (classical) stochastic programming. We…
