Robust LSSVM (R-LSSVM) overcomes the first partly via nonconvex truncated loss function, but the current algorithms for R-LSSVM with the dense solution are faced with the second drawback and are inefficient for training large-scale problems. In this paper, we interpret the robustness of R-LSSVM from a re-weighted viewpoint and give a primal R-LSSVM by the representer theorem. The new model may have sparse solution if the corresponding kernel matrix has low rank. Then approximating the kernel matrix by a low-rank matrix and smoothing the loss function by entropy penalty function, we propose a convergent sparse R-LSSVM (SR-LSSVM) algorithm to achieve the sparse solution of primal R-LSSVM, which overcomes two drawbacks of LSSVM simultaneously. The proposed algorithm has lower complexity than the existing algorithms and is very efficient for training large-scale problems. Many experimental results illustrate that SR-LSSVM can achieve better or comparable performance with less training time than related algorithms, especially for training large scale problems.

Introduction Least squares support vector machine (LSSVM) was introduced by Suykens[1] and has been a powerful learning technique for classification and regression. It has been successfully used in many real world pattern recognition problems, such as disease diagnosis[2], fault detection[3], image classification [4], partial differential equations solving[5] and visual tracking[6]. LSSVM tries to minimize least squares errors on the training samples.

FUKUSHIMA – Tokyo Electric Power Company Holdings Inc. said Monday that it will use a robot cleaner to remove sediment inside reactor 2 at its disaster-stricken Fukushima No. 1 nuclear power plant. The move is designed to make a full-fledged investigation into the reactor by another robot with cameras and dosimeters easier. The robot cleaner, to be placed in the reactor on Tuesday, will jet high-pressure water to remove sediment in the way of the investigative robot. The sediment may contain melted nuclear fuel in addition to corrosive coating materials. The robot cleaner will blow away sediment with water at pressures of some 7.5 megapascals and remove remaining fragments with a device similar in shape to a snowplow.

The number of startups entering the healthcare AI space has increased in recent years, with over 50 companies raising their first equity rounds since January 2015. Deals to healthcare-focused AI startups went up from less than 20 in 2012 to nearly 70 in 2016. Last year also saw two new unicorns emerge in the space: China-based iCarbonX and oncology-focused Flatiron Health. "By 2025, AI systems could be involved in everything from population health management, to digital avatars capable of answering specific patient queries." We identified over 100 companies that are applying machine learning algorithms and predictive analytics to reduce drug discovery times, provide virtual assistance to patients, and diagnose ailments by processing medical images, among other things.

A sex doll company is set to release a robotic sex assistant that can form emotional bonds with its users. Each life-like silicon'RealDoll' is created with a flexible skeleton and requires about 80 hours of work from start to finish, and even has customized genitalia and interchangeable faces. But now the manufacturers of the RealDoll are looking to add another layer of realism to their sex companions, releasing the AI sex assistant system over the course of this year and next year, with the first'robotic head systems' set to be released by the end of the year. Unfinished silicone RealDoll sex dolls hang from chains at the Abyss Creations factory in San Marcos, California. RealDolls are created using Hollywood special effects technology and have orifices made of a special soft grade of silicone for people who want to'enhance their sex lives', according to Abyss Creations The company is set to release their sex assistant app, the Harmony AI app, in April this year and a virtual reality sex system next year.

Babak Hodjat believes humans are too emotional for the stock market. So he's started one of the first hedge funds run completely by artificial intelligence. "Humans have bias and sensitivities, conscious and unconscious," says Hodjat, a computer scientist who helped lay the groundwork for Apple's Siri. "It's well documented we humans make mistakes. For me, it's scarier to be relying on those human-based intuitions and justifications than relying on purely what the data and statistics are telling you."

A warning went out to millions of parents today that schoolchildren could be sending nude selfies after being groomed by paedophiles through a teenage dating app. The children are being lured into sending sexual, 'inappropriate' images of themselves through the Mylol website and mobile dating app. It's feared'pervert' adults are tricking teenagers into sending naked images of themselves. A warning went out to millions of parents today that schoolchildren could be sending nude selfies after being groomed by paedophiles through teenage dating app Mylol. The dating app and site has been labelled as'Tinder for teens' by concerned parents Mylol is a site described as the'number one teen dating site in the US, Australia, UK and Canada.'

As Samsung's unveiling of its make or break Galaxy S8 approaches, the firm's official cases for the handset appear to have leaked online. The leather cases, complete with a Samsung logo, show the S8 will have a fingerprint sensor on the rear - backing previous claims it will have no home button but an'infinity screen' on the front. It also reveals the firm may have added a button just for its new Siri-killer smart AI, called Bixby. The leather cases, complete with a Samsung logo, show the S8 will have a fingerprint sensor on the rear - fitting with previous claims it will have no home button but an'infinity screen' on the front. Bixby could be used for a wide variety of functions in a similar way to Apple's Siri.

A couple of years ago, I spent the summer in Portland, Oregon, losing things. I normally live on the East Coast, but that year, unable to face another sweltering August, I decided to temporarily decamp to the West. This turned out to be strangely easy. I'd lived in Portland for a while after college, and some acquaintances there needed a house sitter. Another friend was away for the summer and happy to loan me her pickup truck. Someone on Craigslist sold me a bike for next to nothing. In very short order, and with very little effort, everything fell into place. And then, mystifyingly, everything fell out of place. My first day in town, I left the keys to the truck on the counter of a coffee shop. The next day, I left the keys to the house in the front door. A few days after that, warming up in the midday sun at an outdoor café, I took off the long-sleeved shirt I'd been wearing, only to leave it hanging over the back of the chair when I headed home. When I returned to claim it, I discovered that I'd left my wallet behind as well. Prior to that summer, I should note, I had lost a wallet exactly once in my adult life: at gunpoint. Yet later that afternoon I stopped by a sporting-goods store to buy a lock for my new bike and left my wallet sitting next to the cash register.

A cable designed to drag space junk out of orbit has failed to deploy from a Japanese spacecraft. More than half a million pieces of debris are currently whizzing around our planet, including abandoned satellites and fragments of old spacecraft. They pose a danger to working satellites and new space vehicles. Scientists are working on a range of clean-up solutions, including cables, nets, harpoons, sails and robotic arms. All are designed to capture pieces of space junk and tug them down into Earth's atmosphere where they will burn up and disintegrate.

Writing in the Economist newspaper on 8 October 2016, US President Barack Obama called out artificial intelligence (AI) as one of several areas where'in recent years we have seen incredible technological advances'.2 Long a backroom area of computer science, AI has captured the popular imagination over the last two years as the range and impact of practical AI applications have expanded at a dizzying pace: a quick search on ft.com for'artificial intelligence and robotics' returned 4 stories from September and October 2014, 16 for the same period in 2015 and 54 in 2016. AI is one of several areas of digital innovation that are all both developing increasingly rapidly and interacting with each other in ways whose consequences are challenging to foresee. A useful portmanteau for these changes is the'fourth industrial revolution'. After steam, electricity and computing, this is the term coined3 by Davos founder Klaus Schwab for the deep digital transformation now upon us.
