Word embeddings are a powerful approach for unsupervised analysis of language. Recently, Rudolph et al. (2016) developed exponential family embeddings, which cast word embeddings in a probabilistic framework. Here, we develop dynamic embeddings, building on exponential family embeddings to capture how the meanings of words change over time. We use dynamic embeddings to analyze three large collections of historical texts: the U.S. Senate speeches from 1858 to 2009, the history of computer science ACM abstracts from 1951 to 2014, and machine learning papers on the Arxiv from 2007 to 2015. We find dynamic embeddings provide better fits than classical embeddings and capture interesting patterns about how language changes.

Algorithmic decision making systems are ubiquitous across a wide variety of online as well as offline services. These systems rely on complex learning methods and vast amounts of data to optimize the service functionality, satisfaction of the end user and profitability. However, there is a growing concern that these automated decisions can lead, even in the absence of intent, to a lack of fairness, i.e., their outcomes can disproportionately hurt (or, benefit) particular groups of people sharing one or more sensitive attributes (e.g., race, sex). In this paper, we introduce a flexible mechanism to design fair classifiers by leveraging a novel intuitive measure of decision boundary (un)fairness. We instantiate this mechanism with two well-known classifiers, logistic regression and support vector machines, and show on real-world data that our mechanism allows for a fine-grained control on the degree of fairness, often at a small cost in terms of accuracy. A Python implementation of our mechanism is available at fate-computing.mpi-sws.org

United States Representative Jason Chaffetz (R-UT) suggested in a Congressional hearing on the use of facial recognition technology by law enforcement officials Wednesday that facial recognition software should be used to identify "people that are here illegally," according to Gizmodo. The Representative who previously drew criticism for saying that Americans who can't afford healthcare should just give up their iPhones, is the chairman of the House Committee on Oversight and Government Reform. Chaffetz's comment on the facial recognition software was in reference to the FBI's use of databases that have more than 400 million American's faces. Representative Chaffetz argued Wednesday that the databases are a privacy concern that could spread to the limiting of certain citizen's rights. He also suggested that if the databases were smaller, or limited "to known criminals, wanted criminals, people that are here illegally, maybe those are the types of things that we should be focused on, as opposed to everybody," they would be more useful because it would be easier for the software to accurately identify people.

Deep learning has been used to transform artificial intelligence (AI) development, whether it is from beating players in games like Go or poker to improving self-driving AI. But perhaps the most important changes for most of us is how AI advances and machine learning are affecting healthcare. In January, a medical startup won FDA approval for an AI-assisted cardiac imaging system called Arterys, and AI is playing vital roles in other health fields such as fighting cancer and aging. NVIDIA boasts that with deep learning, "AI can help doctors make faster, more accurate diagnoses. It can predict the risk of a disease in time to prevent it."

Canada's Liberal government is picking six industrial sectors, led by clean technology, to foster innovation and jobs in an economy that's has been relying on commodities to drive growth. Support will be focused on clean tech, digital, advanced manufacturing, bio-sciences and clean resources, according to Prime Minister Justin Trudeau's second budget released in Ottawa on Wednesday. As part of the effort, the government will consolidate its corporate support programs into one fund and contribute C$400 million ($299 million) in additional venture-capital funding through the country's development bank. "We need to focus on our strengths - areas where we can lead globally and create good jobs for Canadians," Finance Minister Bill Morneau said in his budget speech to lawmakers, according to prepared remarks. Innovation, along with infrastructure, is at the center of Trudeau's efforts to develop a growth agenda that could help bolster support for a deficit-spending plan that will see the country's debt rise C$143 billion over six years.

China has now overtaken Japan for having more robots than anywhere else in the world. The Chinese government is concerned about an ageing population and the rising cost of human labour making Chinese products less competitive. It is giving over $100 Billion in subsidies for companies to replace more human workers with robots. It's hoped that the workers that will no longer work in the factories will move to the growing service sector, in part to help look after the ageing population. Countries In the west have already lost large numbers of manufacturing jobs to china but we shouldn't get too smug about our white-collar jobs in high tech, administration, clerical and production being safe from A.I. systems in the future.

Reacting to concerns about the mass collection of photographs in police databases, U.S. lawmakers plan to introduce legislation to limit the use of facial recognition technology by the FBI and other law enforcement organizations. The FBI and police departments across the country can search a group of databases containing more than 400 million photographs, many of them from the drivers' licenses of people who have never committed a crime. The photos of more than half of U.S adults are contained in a series of FBI and state databases, according to one study released in October. Law enforcement agencies don't need a court-ordered warrant to search the database, members of the House of Representataties Oversight and Government Reform Committee noted during a hearing Wednesday. Yet, the facial recognition system spits out false positive results about 15 percent of the time, with inaccuracies higher when police search for African-Americans and other racial minorities, critics said.

The work of Soviet Director Anatoliy Petrov, Polygon is set on a remote island. A military crew is finishing preparations for a weapon testing range, cutting down palm trees, leveling sand, ejecting natives from their homes. As they work, a soldier notes the next closest island is five kilometers away, and the island is far removed from major shipping lanes and airways. The weapon in question then looms into view -- a gigantic tank. A Professor dressed in white also appears, and as he places a proud hand on the tank's armor plating, the scene flashes back to a younger version of the character, beaming as his son runs to him from the family house.

In the last few months alone, astronomers have alerted the world to several'close shaves' as asteroids of varying sizes whizzed past Earth. While the objects have all flown by at a safe distance, there are still hundreds of thousands that have yet to be identified, causing many people to wonder, 'what if?' Using data from NASA observations of near-Earth objects, a new study has revealed the terrifying scenarios that would take place if a massive space-rock were to slam into a major US city – causing millions of deaths, and injuries for hundreds of miles around. In February, a 328-foot wide object dubbed 2013FK safely passed by Earth, and is set to come around again in 2021. If an asteroid the size of 2013FK were to slam into New York City, there would be more than 2.5 million casualties, according to the study Researchers analyzed more than 36,000 close approaches from NASA's near-Earth object (NEO) database to find out the largest – and closest – to pass by in recent times. The InsuranceQuotes team used an impact calculator to determine the energy of the NEOs, and then converted this into megatons of TNT.

Microsoft has built a special customised version of Windows 10 for the Chinese government. The operating system is available to consumers in China, but the country's government hasn't been overly keen on Windows. It placed a ban on Windows 8 for government use in the aftermath of Edward Snowden's NSA spying revelations, and partnered with Canonical in 2013 in an ultimately doomed effort to create a Windows alternative called Kylin.
