We study the problem of adaptive control in partially observable linear dynamical systems. We propose a novel algorithm, adaptive control online learning algorithm (AdaptOn), which efficiently explores the environment, estimates the system dynamics episodically and exploits these estimates to design effective controllers to minimize the cumulative costs. Through interaction with the environment, AdaptOn deploys online convex optimization to optimize the controller while simultaneously learning the system dynamics to improve the accuracy of controller updates. We show that when the cost functions are strongly convex, after $T$ times step of agent-environment interaction, AdaptOn achieves regret upper bound of $\text{polylog}\left(T\right)$. To the best of our knowledge, AdaptOn is the first algorithm which achieves $\text{polylog}\left(T\right)$ regret in adaptive control of unknown partially observable linear dynamical systems which includes linear quadratic Gaussian (LQG) control.

COVID-19, the disease caused by the SARS-CoV-2 virus, has been declared a pandemic by the World Health Organization, with over 294,000 cases as of March 22, 2020 (WHO, 2020). In this review, we present an overview of recent studies using Machine Learning and, more broadly, Artificial Intelligence, to tackle many aspects of the COVID-19 crisis at different scales including molecular, medical and epidemiological applications. We finish with a discussion of promising future directions of research and the tools and resources needed to facilitate AI research. Executive Summary - There is a broad range of potential applications of AI covering medical and societal challenges created by the COVID-19 pandemic; however, few of them are currently mature enough to show operational impact.

AI tools and services are being used or offered by companies around the world to help fight the coronavirus pandemic. In a best-case scenario, whereby the virus transmission is massively mitigated, researchers from Imperial College London predict "there would still be in the order of 250,000 deaths in GB, and 1.1–1.2 million in the US" resulting from the coronavirus. Imperial College London's analysis landed in Washington over the weekend and it's said to be the reason behind the US stepping up its response. British PM Johnson warned that further measures in the UK will likely be introduced in the coming days and a coronavirus bill for emergency powers is making its way to the House of Commons. Much like in wartime, technologies and social experiments that under normal circumstances would take years or decades to be tested and implemented will be rushed into use in days or weeks.

As the Defense Advanced Research Projects Agency (DARPA) continues exploring emerging technologies for the Department of Defense, it's considering the implementation of artificial intelligence (AI) to tackle electric grid cybersecurity and get ahead of 5G deployment. "In the area of cyber operations, we have a program RADICS [Rapid Attack Detection, Isolation and Characterization Systems], which is designed to help recover critical portions of the power grid in the event of a full blackout caused by malware," Scherlis explained. The program partners with power companies, the National Guard, the Department of Homeland Security, and the Department of Energy to enable a "black start" recovery, a restart to the electric grid without external power, in the event of a cyberattack. Scherlis mentioned the program in context of AI, but the program is generally building new tech to accelerate recovery through improved situational awareness, network isolation, and the ability to adapt to changing cyber situations. "The idea of this program is how can we understand what is the state of affairs in the grid and incrementally restore service, purge the malware, and bring service back to the most critical assets and then stage that out beyond. They've done a number of field trials," Scherlis added.

The pandemic outbreak of novel coronavirus has taken the world by storm. It has created a huge stir across the socio-economic landscape of various countries. Out of 195, the reports say, COVID-19 has infected 192 nations across the globe. While the death toll is rising in other countries like Italy, China is recovering from Wuhan-origin virus with no new domestic cases registered recently, since the outbreak. But how is China recovering while others are getting deep into the unhealthy mess?

It's hard keeping your kids entertained during the coronavirus quarantine, but here are some ways parents figured out how to make it fun. Purchases you make through our links may earn us a commission. Our colleague Mike Snider from the USA TODAY Money team is here to share some news about how you can access Minecraft content for free. Microsoft wants to help students keep flexing their mental muscles even if they aren't in the classroom, with many schools closed during the coronavirus crisis. So kids and parents can explore some free "Minecraft" challenges, made available for free today through June 30 in the Minecraft Marketplace, found within the game played by more than 90 million each month.

The Spanish government is planning to test 80,000 people a day for coronavirus with the roll-out of robot testers. Technology will be used to speed up testing of people in Spain, one of the countries hardest hit by the Covid-19 outbreak, with more than 200 deaths so far. According to Bloomberg, Spanish authorities now plan to increase daily testing from about 20,000 a day to 80,000, by using four robots to apply artificial intelligence (AI) to testing. Speaking at a conference on Saturday 21 March, Raquel Yotti, head of Madrid's health institute, said: "A plan to automate tests through robots has already been designed and Spain has committed to buying four robots that will allow us to execute 80,000 tests per day." Because of the ease that coronavirus spreads from person to person, testing has been identified as one of the best ways to control the disease.

According to him, there are various test kits that get individuals the results of whether or not they have the virus in just 20 seconds, noting that "it is a 96% accuracy rate too." Although Mr Appiah Mensah has faced various backlash from customers following the Menzgold saga, he has noted that the coronavirus menace is a national problem thus taking to his Instagram page to share some tips about how best he believes other countries in the world, especially, how Ghana can deal with the virus to get the needed healing. He said, "The procurement of the AI system developed by a Chinese tech Baidu, which uses cameras equipped computer vision and infrared sensors to do temperature predictions of masses in public places that are indispensable like, Government Ministries and Agencies, transport terminals, Courts market places and so. The AI system is capable of screening up to 200 people per minute and detects their temperature within a range of 0.5 degrees Celsius."

When Darktrace launched in 2013, the world of cybersecurity was an entirely different landscape. "Today, we are used to hearing about artificial intelligence. Six years ago, the idea that you simply couldn't keep all the bad guys out and that companies needed an AI-powered digital immune system to defend against attacks was radical," Poppy Gustafsson, co-CEO of Darktrace, tells Growth Quarters. Fast-forward several years and Darktrace has become of the leading players in the cybersecurity space, in part due to Gustafsson going against the worst advice she ever received: Being told not to do something in a certain way because it went against convention. Darktrace's proprietary technology has of course played a part too.

In 2019, former German Defense Minister Karl-Theodor zu Guttenberg took on a senior leadership position in the artificial intelligence (AI) company Augustus Intelligence. Guttenberg previously urged Europe to take the lead in AI. We have alluded for quite some time to the possibility of Guttenberg leading a united Europe. His gained experience in the United States may further qualify him to lead Europe's digital transformation and more. Augustus Intelligence has recently been involved in a legal dispute with two fired managers, former sales director Marco Pacelli and consultant Ed Crump.
