This paper proposes a strategy to assess the robustness of different machine learning models that involve natural language processing (NLP). The overall approach relies upon a Search and Semantically Replace strategy that consists of two steps: (1) Search, which identifies important parts in the text; (2) Semantically Replace, which finds replacements for the important parts, and constrains the replaced tokens with semantically similar words. We introduce different types of Search and Semantically Replace methods designed specifically for particular types of machine learning models. We also investigate the effectiveness of this strategy and provide a general framework to assess a variety of machine learning models. Finally, an empirical comparison is provided of robustness performance among three different model types, each with a different text representation.

More than 70 advocacy groups have called on the Department of Homeland Security to stop using Clearview AI's facial recognition software. In a letter addressed to DHS Secretary Alejandro Mayorkas and Susan Rice, the director of the White House's Domestic Policy Council, the American Civil Liberties Union, Electronic Frontier Foundation, OpenMedia and other organizations argue "the use of Clearview AI by federal immigration authorities has not been subject to sufficient oversight or transparency." The letter points to a recent BuzzFeed News report that found employees from 1,803 government bodies, including police departments and public schools, have been using the software without many of their bosses knowing about it. The company has given out free trials to individual employees at those organizations hoping that they'll advocate for their agency to sign up for it. Besides the lack of oversight, the letter points to issues like racial bias in facial recognition software and the fact Clearview built its database by scraping websites like Facebook, Twitter and YouTube.

A small robotic helicopter named Ingenuity made space exploration history on Monday when it lifted off the surface of Mars and hovered in the wispy air of the red planet. It was the first machine from Earth ever to fly like an airplane or a helicopter on another world. The achievement extends NASA's long, exceptional record of firsts on Mars. "We together flew at Mars," MiMi Aung, the project manager for Ingenuity, said to her team during the celebration. "And we together now have this Wright brothers moment."

Federal safety regulators have sent a team to investigate the fatal crash of a Tesla electric car in a Houston suburb in which no one was behind the wheel. The National Highway Traffic Safety Administration (NHTSA) said on Monday it had sent a special crash investigation team to Spring, Texas. Investigators are "100% sure" no one was driving the 2019 Tesla Model S on Saturday night when it ran off a road, hit a tree and burst into flames, killing two men inside, Constable Mark Herman of Harris county precinct four said. One man was found in the front passenger seat and the other was in the back seat. KHOU-TV reported that the car was a 2019 Tesla Model S, and the men were aged 59 and 69.

DARPA's Ocean of Things (OoT) program aims to achieve maritime situational awareness over large ocean areas through deploying thousands of small, low-cost floats that form a distributed sensor network. Each smart float will have a suite of commercially available sensors to collect environmental and activity data; the later function involves automatically detecting, tracking and identifying nearby ships and – potentially – close aircraft traffic. The floats use edge processing with detection algorithms and then transmit the semi-processed data periodically via the Iridium satellite constellation to a cloud network for on-shore storage. AI machine learning then combs through this sparse data in real time to uncover hidden insights. The floats are environmentally friendly, have a life of around a year and in buys of 50,000 have a unit cost of about US$500 each.

The U.S. National Security Commission on Artificial Intelligence released its final report recently, listing China as a strategic competitor to the United States in this field. The report describes China as a U.S. peer in many areas and an AI leader in some areas. This new technology allows machines to exhibit characteristics associated with human learning and problem-solving, and can be applied to areas such as facial and speech recognition, natural language processing, and automated reasoning. While China has made technological strides in the AI field, the authors of the report view these developments as a threat. As recorded in the report, potential threatening applications can be made in a number of areas. First, AI boosts the threat imposed by potential cyberattacks coming from China.

As technology becomes a more intimate part of our everyday lives, artificial intelligence is driving progress and helping solve some of society's greatest challenges. BI Norwegian Business School is researching the impact of technology and artificial intelligence on sustainability, gender equality, health and wellbeing, justice, social responsibility, and responsible investment and education. Matilda Dorotic, an associate professor in marketing at the business school, has been involved in extensive research on the impact of technology and big data on diverse aspects of well-being, civil-mindedness, and smart cities--she's recently been invited by the European Commission to talk about the societal issues of implementing artificial intelligence and its far-reaching impact on citizens. It's something we all need to pay more attention to as, according to Matilda "citizens know so little about the ways in which artificial intelligence is fundamentally changing their everyday lives". According to the WHO, cancer is the second leading cause of death worldwide and is responsible for around 10 million deaths per year.

Very early this morning, NASA flew a small drone helicopter that its latest rover had toted to Mars, marking humankind's first controlled and powered flight on another planet. Ingenuity stuck the landing--and space engineers are stoked. Ingenuity ascended about one meter per second, until it rose three meters--about 10 feet above Mars. The helicopter hung as evenly as its state-of-the-art electronics could allow, and then landed where it had been 40 seconds before. Then, Ingenuity pinged its Earth-bound engineers a message they've sought for almost a decade: Mission accomplished.

By now, most people who run small and midsize businesses know that they ought to take advantage of artificial intelligence to make their companies competitive in the digital age. But many don't know how to go about it. To meet this demand, Northeastern, which invested $50 million in a new artificial intelligence research institute last year, will lead a new Massachusetts program, AI Jump Start, to connect small business owners in the state with academic faculty experts to learn how machine learning can grow their companies. The initiative is aimed at a broad range of small and midsize enterprises in defense, manufacturing, health, and other industries whose leaders would like to incorporate artificial intelligence but aren't quite sure where to turn. It's open also to companies that want to upgrade data-driven computing to glean new insights into customers, suppliers, and competitors.

When it comes to maintaining safety online, there are endless things that cross your mind. You need to keep everything secured as a single breach can lead to blunders. Now when it comes to handling your customers' safety and security online, businessmen rely on big data and artificial intelligence blindly. Big data is not a new technology when it comes to advancements in the industry. The latest evolutions help the customers enjoy online safety so that your privacy is not hindered and your clients can rely on you blindly.
