It is no secret that much of the wisdom of the world lies in unstructured data, that is the kind that is not necessarily quantifiable and tidy. So it is in cybersecurity, and now IBM is putting Watson to work to make that knowledge more accessible. Towards that end, IBM Security has announced a new year-long research project through which it will collaborate with eight universities to help train its Watson artificial-intelligence system to tackle cybercrime. Knowledge about threats is often hidden in unstructured sources such as blogs, research reports and documentation, said Kevin Skapinetz, director of strategy for IBM Security. "Let's say tomorrow there's an article about a new type of malware, then a bunch of follow-up blogs," Skapinetz explained.

IBM Security announced Watson for Cyber Security on Tuesday, a cloud-based version of the company's cognitive technology that will focus on learning the language of cybersecurity. The project is working to improve security analysts' capabilities by automating the "connections between data, emerging threats and remediation strategies." IBM will collaborate with eight universities starting this fall to expand the collection of security data IBM has trained Watson with. With its Watson cybersecurity effort, IBM is working to automate threat intelligence, allowing a machine to make connections in data that humans are sometimes unable to find. As an added bonus, if the project proves successful, businesses could integrate Watson's cybersecurity into their security platforms, helping to bridge the cybersecurity skills gap. "Even if the industry was able to fill the estimated 1.5 million open cybersecurity jobs by 2020, we'd still have a skills crisis in security," said Marc van Zadelhoff, General Manager, IBM Security.

That represents a strategic error. The U.S. can and should sell more drones as a way of complementing its foreign policy objectives. After all, some of the top threats to U.S. national security are the very nonstate actors that countries in the Middle East and Africa are buying drones in order to fight. The question is a quasi-legal one. In accordance with the Missile Technology Control Regime, a voluntary arrangement established in the late 1980s and now followed by 34 countries, the United States subjects the sale of military drones and other Category 1 items to "a strong presumption of denial" when determining whether to export to a particular country.

A SpaceX capsule is headed back to Earth with precious science samples from NASA's one-year spaceman. The Dragon left the International Space Station on Wednesday morning, bound for an afternoon splashdown in the Pacific. The station's big robot arm set the Dragon free over Australia. The capsule had been at the station since April 10, dropping off supplies as well as an experimental, inflatable room that will pop open in two weeks. Nearly 4,000 pounds of items are packed into the Dragon, including blood and urine samples from astronaut Scott Kelly's one-year mission.

I'll introduce the Hierarchical Risk Parity (HRP) approach. HRP portfolios address three major concerns of quadratic optimizers in general and Markowitz's CLA in particular: instability, concentration and under-performance. HRP applies modern mathematics (graph theory and machine learning techniques) to build a diversified portfolio based on the information contained in the covariance matrix. However, unlike quadratic optimizers, HRP does not require the invertibility of the covariance matrix. In fact, HRP can compute a portfolio on an ill-degenerated or even a singular covariance matrix, an impossible feat for quadratic optimizers.

The White House is doing a lot more thinking about the arrival of automated decision-making -- super-intelligent or otherwise. No one in government is yet screaming "Skynet," but in two actions this week the concerns about our artificial intelligence future were sketched out. The big risks of A.I. are well-known (a robot takeover), but the more immediate worries are about the subtle, or not-so-subtle, decisions made by badly coded and designed algorithms. President Barack Obama's administration released a report this week that examines the problem associated with poorly designed systems that, increasingly, are being used in automated decision making. Algorithmic systems can affect employment, education, access to credit -- anything that relies on computer-assisted decisions.

Nasa has announced that it has found evidence of flowing water on Mars. Scientists have long speculated that Recurring Slope Lineae -- or dark patches -- on Mars were made up of briny water but the new findings prove that those patches are caused by liquid water, which it has established by finding hydrated salts. Several hundred camped outside the London store in Covent Garden. The 6s will have new features like a vastly improved camera and a pressure-sensitive "3D Touch" display

Kudos to the Mr Robot production team, who are finding new ways to make us feel very excited about what's going to happen in season two. But yesterday, a new'command' input appeared on the site: fivenine. It refers to the date (9th May, or 5/9 in US date format). Type in'fivenine', press enter, and see how Mr Robot just raised its marketing game. Yes, that is President Barack Obama talking about an "attack" that will "affect our economy in ways that are extraordinarily significant". You can go to the video directly using this link.

TORONTO – A dating website is pledging to match Americans who can't live with a Donald Trump presidency to Canadians looking for love, facilitating the pledge often made by U.S. voters to move to Canada if the real estate billionaire is elected. "Maple Match makes it easy for Americans to find the ideal Canadian partner to save them from the unfathomable horror of a Trump presidency," the Maple Match website reads, before offering a waiting list for interested singles. Trump's bombastic campaign to lead the Republican Party to the November presidential election has alarmed some Americans, both liberals and those in his own party, and the pledge by some to move to Canada if he is elected has gathered steam. In February, the island of Cape Breton on Canada's Atlantic coast marketed itself as a tranquil refuge for Americans seeking to escape should Trump capture the White House. The Maple Match website allows users to add their name to a wait list matching dismayed U.S. voters with interested single Canadians, adding "We'll let you know the next steps soon!" Officials with Maple Match did not immediately respond to a request for comment, but Chief Executive Joe Goldman told the Canadian Broadcasting Corp. that more than 10,000 singles and about 2,500 Canadians had signed up for the website's waiting list as of Tuesday morning.

Imagine workers who don't pay taxes, with no IRS worries. Or who don't get paid for overtime. Now, imagine a robot on the job. "Robotics will be a revolution for our economy and in the way we think and act," said Randy Bateman, an economist who is the CEO and president of Balcones Investment Research. Bateman, appearing recently on a futuristic panel discussion titled "Will a Robot Take Your Job?" at the libertarian Cato Institute in Washington, expects the robotics industry to spearhead the next great transformative stage of our workforce.
