Rio de Janeiro's police force, like the rest of the city's public services, is broke. In the headquarters of the bomb-disposal unit, supplies of everything from soap to explosives are running out as the city struggles to pay its debts amid Brazil's deep recession. But, poor as it is, Rio's bomb squad is one of the most technologically advanced in South America. In the cramped storeroom of its base in northern Rio, a state-of-the-art robot takes pride of place. "The robot is a fundamental piece of equipment--it's vital to our day-to-day work," says the bomb squad's boss, Marcelo Corrêa.

Boosting as gradient descent algorithms is one popular method in machine learning. In this paper a novel Boosting-type algorithm is proposed based on restricted gradient descent with structural sparsity control whose underlying dynamics are governed by differential inclusions. In particular, we present an iterative regularization path with structural sparsity where the parameter is sparse under some linear transforms, based on variable splitting and the Linearized Bregman Iteration. Hence it is called \emph{Split LBI}. Despite its simplicity, Split LBI outperforms the popular generalized Lasso in both theory and experiments. A theory of path consistency is presented that equipped with a proper early stopping, Split LBI may achieve model selection consistency under a family of Irrepresentable Conditions which can be weaker than the necessary and sufficient condition for generalized Lasso. Furthermore, some $\ell_2$ error bounds are also given at the minimax optimal rates. The utility and benefit of the algorithm are illustrated by several applications including image denoising, partial order ranking of sport teams, and world university grouping with crowdsourced ranking data.

The meaning of "work" is changing, and with life expectancies growing, the gig economy taking hold and artificial intelligence taking plenty of people's jobs, millennials will have careers that are worlds away from those of their forebears, says Dr. Linda Sharkey, global managing director of the consulting firm Achieveblue Inc. Sharkey is the author of "The Future-Proof Workplace: Six Strategies to Accelerate Talent Development, Reshape Your Culture and Succeed with Purpose," co-written with Morag Barnett, the chief executive of the business management consultancy SkyeTeam. She talked to International Business Times about the prospects for 21st-century careers, the falling value of a four-year degree and the idea that a robot might be conducting this sort of question-and-answer article in the not-so-far-away future. This interview has been edited and condensed for clarity. One issue you touch on in your book is your expectation that retirement will cease to be a 21st century phenomenon, and that today's young workers are more likely to take sabbaticals than end their careers by their late sixties. Is this something you think will be born of choice -- a desire to work longer -- or a consequence of the unsustainability of Social Security as generations live longer and have fewer children?

Equipped with a state-of-the-art thermal camera, the drone crisscrossed the field, scanning it for cool, soggy patches where a gopher may have chewed through the buried drip irrigation line and caused a leak. In the drought-prone West, where every drop of water counts, California farmers are in a constant search for ways to efficiently use the increasingly scarce resource. Cannon Michael is putting drone technology to work on his fields at Bowles Farming near Los Banos, 120 miles southeast of San Francisco. About 2,100 companies and individuals have federal permission to fly drones for farming, according to the drone industry's Association for Unmanned Vehicle Systems International. Federal regulators planned to relax the rules Monday on commercial drones, a move that could spur even greater use of such aircraft on farms. Michael is descended from Henry Miller, a renowned cattle rancher, farmer and Western landowner who helped transform semi-arid central California into fertile farmland 150 years ago by building irrigation canals, some still flowing today.

China, the most populous country in the world, has close to one billion people that speak Mandarin. Spanish is spoken by a less than half that number, primarily in Mexico, Spain and the countries in South America. English follows close behind, with Hindi in India and Arabic in the Middle East making up the top five. Or so you would think. The most common language in the world is actually not human at all.

Click on the blue word above the attention of the medical profession, every day there are material! When it comes to Dr. Siddartha (Siddhartha Mukherjee), perhaps a lot of people are unfamiliar with his name. But a lot of people are familiar with his two book, "the king of all diseases: cancer," and "genes: Intimate History.". The former allows Dr. Mukherjee to get a non fiction Pulitzer prize, while the latter was recommended as the best book of 2016 by Mr. Bill Gate. Recently, Dr. Mukherjee in "New York guest" (The New Yorker) published a long article, the unique perspective of a doctor, artificial intelligence survey in recent years the impact for medicine. The seven story is he in this long article record, outlines the future doctors and artificial intelligence, harmonious coexistence. The author Dr. Mukherjee is a doctor, but also a good writer. One night in November 2016, a 54 year old woman in New York, Bronx (Bronx) was sent to the emergency room at the Columbia University (Columbia University) medical center because of a severe headache. She told the emergency room doctor that his vision was blurred and his left hand was numb. The doctor arranged for CT. A few months later, on January, one of the 4 radiologists huddled in front of a computer on the third floor of the hospital, the room was dark and windowless, with only the screen light, which seemed to be filtered by the sea. She's training them to read CT. "Once the brain shows death and gray, it's easy to diagnose a stroke," Dr. Lignelli-Dipple said. The key is to diagnose a stroke before most nerve cells die." A stroke is usually caused by a blockage or bleeding of the blood vessel. The radiologist has about 45 minutes of window time so that the doctor can intervene in time to dissolve the clot. "Imagine you're in the emergency room right now," continued Dr. Lignelli-Dipple. "Every minute, a part of the brain dies.

Every few months it seems another study warns that a big slice of the workforce is about to lose their jobs because of artificial intelligence. Four years ago, an Oxford University study predicted 47% of jobs could be automated by 2033. Even the near-term outlook has been quite negative: A 2016 report by the Organization for Economic Cooperation and Development (OECD) said 9% of jobs in the 21 countries that make up its membership could be automated. And in January 2017, McKinsey's research arm estimated AI-driven job losses at 5%. My own firm released a survey recently of 835 large companies (with an average revenue of $20 billion) that predicts a net job loss of between 4% and 7% in key business functions by the year 2020 due to AI. Yet our research also found that, in the shorter term, these fears may be overblown.

In late February, the UN-Secretary General held a press conference, highlighting the risk of starvation in East Africa and the necessity to raise funds to address the emergency situations in Somalia and South Sudan. Drought has been back in these countries and their neighbours since 2016, leading to a huge current food crisis. While governments are trying to handle the situation, how could technology innovations help prevent starvation and improve agriculture management in the future? We met with Laurent Rivière, a French 30 years-old entrepreneur, who shared with us his view on the subject with a combination of engineer pragmatism and changemaker idealism . Founder and CEO at Sunbirds for two years, he explained to us how his "bird of the sun," his solar drone, is addressing the agriculture challenges of the 21st century.

If you enjoy navigating distant galaxies, leading intergalactic alliances and fighting space pirates, you might want to take on another challenge: discovering real planets. The space-based online game EVE Online, which bills itself as "the world's largest living work of science fiction", is delving into science fact by asking players to help search for planets outside our solar system. Details of the citizen science challenge, which is part of an initiative called Project Discovery, emerged at the game's annual Fanfest event in Reykjavik, Iceland, last week. A mini-game launching later this year within the EVE universe will present players with data from the now defunct COROT space observatory, which launched in 2006. They will be looking at luminosity curves, representing the change in a star's brightness as a planet passes in front of it.

Every day, millions of people make buying decisions based on search – products to buy, restaurants in the neighborhood, and tons of other choices. According to the Nielsen Report "Global Trust in Advertising" however, while consumers rely on online opinions or price comparisons, more often than not, it's word-of-mouth recommendations that are the most effective. The most credible advertising comes straight from the people we know and trust, and over 83% of respondents completely or somewhat trust the suggestions of friends and family. So when we make a final decision to buy, it's reasonable to assume that we ask a spouse, relatives or close friends for advice. After all, they are the ones who know us, our tastes, preferences, sense of fashion, etc.
