Heterogeneous network embedding (HNE) is a challenging task due to the diverse node types and/or diverse relationships between nodes. Existing HNE methods are typically unsupervised. To maximize the profit of utilizing the rare and valuable supervised information in HNEs, we develop a novel Active Heterogeneous Network Embedding (ActiveHNE) framework, which includes two components: Discriminative Heterogeneous Network Embedding (DHNE) and Active Query in Heterogeneous Networks (AQHN). In DHNE, we introduce a novel semi-supervised heterogeneous network embedding method based on graph convolutional neural network. In AQHN, we first introduce three active selection strategies based on uncertainty and representativeness, and then derive a batch selection method that assembles these strategies using a multi-armed bandit mechanism. ActiveHNE aims at improving the performance of HNE by feeding the most valuable supervision obtained by AQHN into DHNE. Experiments on public datasets demonstrate the effectiveness of ActiveHNE and its advantage on reducing the query cost.

Virgin's internet service appears to have stopped working, with people unable to get online. The company's mobile data service appears to have broken for at least some users, who are unable to make calls or get online. The issues started around lunchtime, according to the website Down Detector. They were reported across the country, it said. While the Virgin Media Twitter account has been hit by a huge number of complaints, it has yet to respond to the problems publicly.

An Elon Musk-backed startup looking to connect human brains to computers has raised most of its $51 million funding target. According to a report by Bloomberg, Neuralink has raised $39 million of its planned $51 million funding round as per a filing with the Securities and Exchange Commission (SEC). Prior funding rounds date back two years when the company raised $27 million after aiming for as much as $100 million. While it's unclear what progress Neuralink has made in its technology, if any, the filings come less than a month after the SpaceX and Tesla CEO foreshadowed the startup's endeavors in an ambiguous tweet. In a response on Twitter, Musk said Neuralink technology is'coming soon.' Elon Musk believes humans must link up with machines in order to fight the inevitable onslaught of artificial intelligence.

South Korea is developing robots that mimic wildlife adapted for all environments on Earth for military warfare. The nature inspired technology, known as biomimetics, will form part of the country's future weapons systems and help its soldiers in battles. Robot designs inspired by birds, snakes and marine species aim to cover both surveillance and combat via sea, land and sky. It is an attempt to catch up with neighbouring countries such as China and Russia who have made huge advances in the application of the technology, said a defence agency personnel. South Korea is developing a range of robots that mimic wildlife adapted for all environments on Earth for military warfare.

Liz O'Sullivan says she struggled for months as she learned more about the military project her in which her employer, Clarifai, was participating. Liz O'Sullivan says she struggled for months as she learned more about the military project her in which her employer, Clarifai, was participating. On the night of Jan. 16, Liz O'Sullivan sent a letter she'd been working on for weeks. It was directed at her boss, Matt Zeiler, the founder and CEO of Clarifai, a tech company. "The moment before I hit send and then afterwards, my heart, I could just feel it racing," she says.

A technician works in a lab at GeseDNA Technology in Beijing. To counter China, the U.S. plans to impose new export restrictions on "emerging and foundational technology" that researchers say could affect the way they share genetic materials with international labs.

It takes just 3.7 seconds of audio to clone a voice. This impressive--and a bit alarming--feat was announced by Chinese tech giant Baidu. A year ago, the company's voice cloning tool called Deep Voice required 30 minutes of audio to do the same. This illustrates just how fast the technology to create artificial voices is accelerating. In just a short time, the capabilities of AI voice generation have expanded and become more realistic which makes it easier for the technology to be misused.

No matter the domain, data-intensive apps share one requirement in common: a reliable file system that ensures data is available to them on demand. Pure Storage, NetApp, VAST Data, IBM Spectrum Scale, and Dell EMC provide this, as does San Jose, California-based company WekaIO. WekaIO's high-velocity Matrix platform takes advantage of flash storage, off-the-shelf components, and sophisticated software techniques to deliver enormous speedups at exabyte scale. In fact, the company claims Matrix is the fastest parallel file system on the market for AI and technical compute workloads, as measured by independent SPEC SFS 2014 benchmark tests. To lay the groundwork for future growth in AI and analytics, life sciences, manufacturing, media and entertainment, and financial services, WekaIO has closed a $31.7 million series C financing round led by Hewlett Packard Enterprise (HPE), with participation from a host of storage and computing industry giants including Mellanox, Nvidia, Seagate, Western Digital Capital, and Qualcomm.

Artificial intelligence can help to bring together the twin megatrends of digitalization and decarbonisation. There has been a lot of talk about how artificial intelligence (AI) will affect various aspects of our lives, but little has been said to date about how the technology can help to make the world more sustainable. A new report from the consultancy PwC, commissioned by software giant Microsoft, looks at how the twin, powerfully disruptive megatrends of digitization and decarbonisation could come together in future and it concludes that AI could make a significant dent in global greenhouse gas (GHG) emissions. PwC defines AI as "a collective term for technologies that can sense their environment, think, learn, and take action in response to what they're sensing and their objectives". Applications can range from automation of routine tasks to augmenting human decision-making and beyond to automation and discovery – huge amounts of data to spot, and act on patterns, which are beyond our current capabilities.

Artificial Intelligence is on the cusp of becoming the biggest technology of the information age, says Horacio Rozanski, president and CEO of Booz Allen Hamilton. However, we need to bake human judgement into it before it is too late, he writes in this opinion piece. The exponential pace of technological advancement has made it more challenging than ever before to address its unintended consequences. We have seen it with digital innovation, especially social media, and we are only just beginning to contemplate it with artificial intelligence, which holds the promise of being the most transformational technology of the information era. The unanticipated consequences of digital innovation have been well documented.
