The sudden onset of deleterious and oscillatory dynamics (often called instabilities) is a known challenge in many fluid, plasma, and aerospace systems. These dynamics are difficult to address because they are nonlinear, chaotic, and are often too fast for active control schemes. In this work, we develop an alternative active controls system using an iterative, trajectory-optimization and parameter-tuning approach based on Iterative Learning Control (ILC), Time-Lagged Phase Portraits (TLPP) and Gaussian Process Regression (GPR). The novelty of this approach is that it can control a system's dynamics despite the controller being much slower than the dynamics. We demonstrate this controller on the Lorenz system of equations where it iteratively adjusts (tunes) the system's input parameters to successfully reproduce a desired oscillatory trajectory or state. Additionally, we investigate the system's dynamical sensitivity to its control parameters, identify continuous and bounded regions of desired dynamical trajectories, and demonstrate that the controller is robust to missing information and uncontrollable parameters as long as certain requirements are met. The controller presented in this work provides a framework for low-speed control for a variety of fast, nonlinear systems that may aid in instability suppression and mitigation.

One of the most appealing aspects of games set in the Star Wars universe is that you get to concoct scenes and stories we would never see in the movies. Whether you're playing Knights of the Old Republic, Jedi: Fallen Order or the old Star Wars role-playing board game designed by Greg Costikyan in the 1990s, there will be individual moments unrepeatable on the big screen. I know this, because I just won a round of the new trading card game Star Wars Unlimited thanks to a heroic C-3PO wielding Luke Skywalker's lightsaber. On a basic level, Star Wars Unlimited works like most modern trading card games, such as Yu-Gi-Oh! You and an opponent each have a deck of cards, most of which feature a single character or vehicle, with a number for health and another number for power/damage.

Many practical problems involve estimating low dimensional statistical quantities with high-dimensional models and datasets. Several approaches address these estimation tasks based on the theory of influence functions, such as debiased/double ML or targeted minimum loss estimation. This paper introduces \textit{Monte Carlo Efficient Influence Functions} (MC-EIF), a fully automated technique for approximating efficient influence functions that integrates seamlessly with existing differentiable probabilistic programming systems. MC-EIF automates efficient statistical estimation for a broad class of models and target functionals that would previously require rigorous custom analysis. We prove that MC-EIF is consistent, and that estimators using MC-EIF achieve optimal $\sqrt{N}$ convergence rates. We show empirically that estimators using MC-EIF are at parity with estimators using analytic EIFs. Finally, we demonstrate a novel capstone example using MC-EIF for optimal portfolio selection.

The study of energetics necessarily involves numerous scientific domains, spanning shock physics and detonation science, fluid dynamics, material science, thermodynamics, and chemical synthesis. The plethora of sub-disciplines of math, physics, chemistry, and engineering pose a challenge to practitioners who would wish to amass an expertise of energetics. Furthermore, maintaining awareness of advancements in energetics research is complicated by the exponential rate at which new research is published across scientific disciplines, including energetics. Thus, the development of automated and intelligent approaches for extracting knowledge from papers, reports, textbooks, and patents related to energetics could aid researchers and accelerate progress in energetics science. Natural Language Processing (NLP) is a sub-field of linguistics, computer science, and Machine Learning (ML) involving the interactions between computers and human (natural) languages. NLP techniques are used to analyze and generate human language, allowing computers to read, interpret, and understand text and speech. In the context of energetics research, NLP can be used to analyze large volumes of textual data, such as scientific papers, technical reports, and patents, in order to extract relevant information about the concepts that underlie and explain energetics phenomenon. Furthermore, NLP can enable natural language understanding that could be further applied to text mining journal articles and performing numerous natural language tasks such as classification, summarization, and recommendation. Overall, the use of NLP in energetics research has the potential to enhance our understanding of energetic materials and phenomenon, and assist in the development novel propellants, explosives, and pyrotechnics.

Enterprise data cloud company Cloudera's new study, "Limitless: The Positive Power of AI," released in March, is based on two online surveys conducted by Sapio Research in August 2021. For the first, 10,880 knowledge workers working in companies with 1,000 employees were surveyed in 16 countries including France (1,000 respondents), and for the second 2,213 business decision-makers, in the same countries and organization profile (150 French respondents). The study examines their changing attitudes towards AI, machine learning (ML) and data analytics. The research results show that workers are not afraid of AI replacing them. An explosion in the amount of data now available to companies has made AI/ML a common thread in many jobs and a powerful ally.

The DARPA Lifelong Learning Machines (L2M) program seeks to yield advances in artificial intelligence (AI) systems so that they are capable of learning (and improving) continuously, leveraging data on one task to improve performance on another, and doing so in a computationally sustainable way. Performers on this program developed systems capable of performing a diverse range of functions, including autonomous driving, real-time strategy, and drone simulation. These systems featured a diverse range of characteristics (e.g., task structure, lifetime duration), and an immediate challenge faced by the program's testing and evaluation team was measuring system performance across these different settings. This document, developed in close collaboration with DARPA and the program performers, outlines a formalism for constructing and characterizing the performance of agents performing lifelong learning scenarios. In Section 2, we introduce the general form of a lifelong learning scenario.

Fire Tablets and Echo speakers are some of the cheapest personal tech devices around. They're built to be affordable, and some of them are especially cheap for Prime Day. Kindles are a different story. They're more expensive and go on sale less often. We've compiled every decent Prime Day deal on the Amazon-branded devices we've tested (and like!).

Ted Sergott, EVP, Product Development at PRO Unlimited, is responsible for all aspects of PRO's Vendor Management System, Wand. In just a few months, the coronavirus pandemic has changed the candidate sourcing and talent landscape. According to a Gallup poll, 70% of the workforce was always or sometimes working remotely in April 2020. Workers and organizations have had to adjust to this "new normal," which offers both challenges and opportunities. For savvy organizations, one such opportunity is the ability to source contingent job positions in previously untapped locations, which can open up possibilities to lower costs, reduce fill times, and increase talent levels and diversity.

Imagine some day in the future you are sitting at your computer and suddenly it starts playing soothing music to help alleviate your stress levels. Or after a long morning, it advises you to take a break as you are starting to look tired. Although such ideas will either sound like a great approach to health and wellbeing, or rather creepy, depending on your point of view, much of the technology to transform such notions into reality already exists. For example, neuromarketers, who study the brain's responses to both marketing and advertising, have for some time been using facial coding software via webcams to read consumers' expressions to understand their emotional reactions. So it is not a huge leap to think of these systems being reapplied in the workplace to boost employee engagement, which remains a key preoccupation of many leaders.
