Machine learning teaches computers to do what comes naturally to humans: learn from experience. Machine learning algorithms use computational methods to "learn" information directly from data without relying on a predetermined equation as a model. The algorithms adaptively improve their performance as the number of samples available for learning increases. Machine learning uses two types of techniques: supervised learning, which trains a model on known input and output data so that it can predict future outputs, and unsupervised learning, which finds hidden patterns or intrinsic structures in input data. The aim of supervised machine learning is to build a model that makes predictions based on evidence in the presence of uncertainty.

Police in southeast China have reportedly arrested a fugitive spotted in a crowd of 50,000 people attending a pop concert thanks to some eerily accurate facial recognition technology. According to local reports, the man was arrested while attending a show by Hong Kong singer Jacky Cheung in the Nanchang, Jiangxi province. The man's full name hasn't been released but he is described in reports by his family name, Ao. "Ao was suspected to be involved in an economic crime and was listed on a national online system," police officer Li Jin is quoted as saying. "He was very shocked and had a blank face when we caught him." Ao had reportedly thought that he was safe to attend the crowded event because he considered that there was minimal chance that he would be identified in such a large group of people.

In internet era, users grant Internet companies permission on collecting their personal data for connecting with creditable users and content out of convenience. For example, the magazine publishes articles on Facebook because Facebook allows users to subscribe their article. At the same time, the publisher can manage their subscribers' relationship with messenger system. The recommendation system helped to rank users and their content published. All the free services are sponsored from advertisements, which pay the cost of internet space and traffic.

IMAGE: With new, artificial intelligence approach, scientists discovered metallic glass 200 times faster than with an Edisonian approach. But once in a while, under just the right conditions, you get something entirely new: a futuristic alloy called metallic glass. The amorphous material's atoms are arranged every which way, much like the atoms of the glass in a window. Its glassy nature makes it stronger and lighter than today's best steel, and it stands up better to corrosion and wear. Although metallic glass shows a lot of promise as a protective coating and alternative to steel, only a few thousand of the millions of possible combinations of ingredients have been evaluated over the past 50 years, and only a handful developed to the point that they may become useful.

The UAE's smart monitoring, alert and control systems are being showcased at the Gartner Symposium ITxpo in Dubai. "This symposium is an extremely insightful key event in the UAE and the region. Tayara takes care of all commercial ICT engagements. "We are building solutions or POCs (Proof of Concept) for our partners. We are showcasing the Smart Dubai platform, the Dubai Pulse, which is an end-to-end integrated platform that supports infrastructure services, computing, data hosting and storage for the government all the way up to blockchain and artificial intelligence (AI). Real utilisation of data sets is available in the city to empower senior management to take insightful rather than legacy decisions."

These and many other fascinating findings are from the recently released Centrify and Dow Jones Customer Intelligence study, CEO Disconnect is Weakening Cybersecurity (31 pp, PDF, opt-in). One of the most valuable findings from the study is how CEOs can reduce the risk of a security breach meltdown by rethinking their core cyber defense strategy by maturing their identity and access management strategies. However, 62% of CEOs have the impression that multi-factor authentication is difficult to manage. Thus, their primary security concern is primarily driven by how to avoid delivering poor user experiences. In this context, machine learning can assist in strengthening the foundation of a multi-factor authentication platform to increase effectiveness while streamlining user experiences.

The Lincoln Journal Star reports that a crashed drone attached with bags of marijuana and tobacco was found at the Lincoln Correctional Center two months ago. The Justice Department reported last year an increasing number of attempts to use drones to smuggle contraband into federal prisons over the past five years.

The problem: The animation, which looked pretty real, was fake. The teen March for Our Lives activist never put her hands on the Constitution--the animation was a doctored version of her shredding a shooting range target. Welcome to the troubling world of "deep fakes." Earlier this year, Reddit took down a number of forums devoted to creating bogus videos, often pornographic, featuring one person's face swapped in for another. Open source artificial intelligence software makes the process radically simpler and more efficient than traditional video editing tools.

THE PLANNED boycott of the Korea Advanced Institute of Science and Technology (KAIST) over its research into military robots has been cancelled after the lab agreed to step back from the brink of madness. The state-run lab known as Research Centre for the Convergence of National Defence and Artificial Intelligence (RCCNDAI, presumably) was working in partnership with defence company Hanwa, a company which develops so-called'cluster munitions' which are banned in over 100 countries and a completely autonomous sentry robot called SGR-A1 - echoes of ED-209 anyone? Toby Walsh, Scientia Professor of Artificial Intelligence at the University of New South Wales in Sydney, who initiated the action, praised KAIST for the rapid response. "I was very pleased that the president of KAIST has agreed not to develop lethal autonomous weapons, and to follow international norms by ensuring meaningful human control of any AI-based weapon that will be developed," he said. "I applaud KAIST for doing the right thing, and I'll be happy to work with KAIST in the future. "It goes to show the power of the scientific community when we choose to speak out - our action was an overnight success," he added. "We initially sought assurances in private from the university more than month ago about the goals of their new lab.
