A drone camera films a herd of caribou as they migrate in Western Canada. The footage offers a unique look at the behavior of individuals within the herd. Flying cameras are giving biologists an all-encompassing view of migration that reveals how social interactions motivate the animals' every move. Ecologists Andrew Berdahl, a Santa Fe Institute fellow, Colin Torney of the University of Glasgow, and colleagues flew drones to capture footage of Dolphin and Union caribou, a Canadian herd, as the animals crossed from Victoria Island to the Canadian mainland in the last stage of their fall migration. Scientists have long pondered the dynamics of animal migrations, but they've had limited ways to study them.

LONDON, UK – Think back to your last year in customer interactions. How many customer complaints did you process? Out of those, how many people complained about contact centre wait times? Now, ask yourself: how many of those customers were angry, sad, or dissatisfied about the level of service they received? Satisfying customers, it seems, is a neverending challenge.

You may have seen this striking chair designed by Autodesk's generative CAD software: It began with a primitive description of a chair: a platform of certain dimensions held above the ground by a certain height, able to carry a certain amount of weight. From there, a computer tested billions of possible configurations, evaluating each one for strength, stability, and material usage. As it worked, the software developed what's known in machine learning as a "gradient"--a map that relates how outcomes change with respect to objectives as you vary inputs. In this case, the inputs are bits of matter added to or subtracted from any part of the chair, and the outcome is a combination of strength, stability, and material usage. As the computer varied the design of the chair, arbitrarily at first, it began to identify the most promising avenues of design and spent its efforts in those directions. "Gradient descent"--this process of informed search through an almost infinite field of possibilities--is one of the foundations of artificial intelligence, and the ability to perform gradient descent operations has that has advanced rapidly in the last five years, thanks to both algorithmic advances and cheaper, more powerful computing.

The mere mention of artificial intelligence (AI) often conjures up images of ultraintelligent robots that process millions of gigabytes of data, before spitting out insights that would have taken humans months of laborious work. But a US-based start-up believes that humans still need to be at the centre of it all. San Francisco-based Unanimous AI has developed artificial intelligence technology based on swarm intelligence – known as the collective behaviour often displayed when groups of people or animals amplify intelligence by working together as a group. The company blends human decision-making processes with AI algorithms to determine the best solution in a question posed to a group of human participants, referred to as a swarm. The swarm is tasked with collectively finding the best answer to the question posed to them, while Unanimous AI's algorithms assess everything from the amount of time it takes for a participant to come to a decision and even the level of conviction they have in their choice.

Healthcare has undergone a transformation over the past several years, shifting from paper-based records systems to electronic records, as well as incorporating digital health monitoring devices and other advanced patient screening systems. These advances have led to an explosion of data, which can best be manipulated and analyzed by artificial intelligence (AI) technology. In healthcare, according to a new report from Tractica, AI is largely being implemented as a tool to more efficiently and accurately review data, and uncover patterns in the data that can be used to improve analyses, uncover inefficiencies, and streamline care, from both a clinical and an operational perspective. The market intelligence firm finds that the overarching driver in these AI implementations is to provide better care for patients, while reducing costs and administrative headaches and bottlenecks. Tractica forecasts that global software revenue from 21 key healthcare AI use cases will grow from $165 million in 2017 to $5.6 billion annually by 2025.

It took six weeks but "Black Panther" has finally been unseated as the top film at the box office. The monsters vs. robots science-fiction sequel "Pacific Rim: Uprising" dethroned "Black Panther" with an estimated $28 million.

A copy of'The Observer' shows an advertisement paid by Facebook in London, March 25, 2018. Facebook Chief Executive Mark Zuckerberg apologized for a "breach of trust" involving misused data from millions of Facebook users. The ads also appeared in The New York Times, Washington Post and Wall Street Journal. SAN FRANCISCO -- As Facebook continues to buffet winds of criticism, its founder took out full page ads in U.S. and British newspapers Sunday to apologize to consumers for not properly securing their personal data. "This was a breach of trust, and I'm sorry we didn't do more at the time," Mark Zuckerberg said in the signed ad, which was published in The New York Times, The Wall Street Journal, The Washington Post and six British papers.

Tech giant Microsoft will host'AI for All' summit in Bengaluru on March 28 to showcase use cases of artificial intelligence across sectors. The event will feature discussions around the benefits of artificial intelligence (AI), and how this can be used to amplify human ingenuity, a Microsoft India spokesperson told PTI. "This is our first summit of its kind in the country. While we had an AI event last year for developers, this one is for a broader audience," the spokesperson added. Participation is expected from industry representatives spanning across verticals like healthcare, auto and IT and IT-enabled services, among others. The event will be addressed by global and Indian Microsoft executives, including Peggy Johnson (Executive Vice President, Business Development), Anant Maheshwari (President, Microsoft India) and Anil Bhansali, Managing Director at Microsoft India (R&D).
