After twice being denied visas, a team of Afghan girls has been permitted to travel to the U.S. for a robotics competition. The team takes a photo at Herat International Airport on Thursday. After twice being denied visas, a team of Afghan girls has been permitted to travel to the U.S. for a robotics competition. The team takes a photo at Herat International Airport on Thursday. It has been an odyssey, but finally, a team of six Afghan girls will be able to travel to the United States to compete in a robotics tournament.

The fight between Floyd Mayweather and Conor McGregor promises to be the biggest bout of 2017, though it won't be cheap to watch. Buying the fight on pay-per-view will cost nearly $100, and no tickets can be had for fewer than $500. The upcoming Aug. 26 bout has been compared to the fight between Mayweather and Manny Pacquiao on May 2, 2015. It generated a record 4.6 million buys, even though it cost $99.95 in HD. Mayweather-McGregor will also cost $99.95,

At the Institute of Cognitive Science at Osnabrück University, Germany, virtual reality has become a training ground for machine morality. Leon René Sütfeld, a Ph.D. student in cognitive science, studies human responses to danger and obstacles in traffic scenarios, using this data to train and evaluate decision-making models for algorithms. The need for ethical machines may be one of the defining issues of our time. Algorithms are created to govern critical systems in our society, from banking to medicine, but with no concept of right and wrong, machines cannot understand the repercussions of their actions. A machine has never thrown a punch in a schoolyard fight, cheated on a test or a relationship, or been rapt with the special kind of self-doubt that funds our cosmetic and pharmaceutical industries.

Amazon Echo is a hands-free speaker controlled with your voice. It features a personal assistant called Alexa, who will perform various tasks for you and control various systems. There are seven microphones within Echo, all of which feature enhanced noise cancellation and far-field voice recognition, meaning you can ask Alexa a question from any direction, even when playing music, and she should still hear you. Amazon Echo's personal assistant will respond to the wake word "Alexa". If you have more than one Echo, or Echo Dot in your home, Alexa will respond from the device closest to you.

AT THE start of this year, two straws in the wind caught the attention of those who follow the development of artificial intelligence (AI) globally. First, Qi Lu, one of the bosses of Microsoft, said in January that he would not return to the world's largest software firm after recovering from a cycling accident, but instead would become chief operating officer at Baidu, China's leading search engine. Later that month, the Association for the Advancement of Artificial Intelligence postponed its annual meeting. The planned date for the event in January conflicted with the Chinese new year. These were the latest signals that China could be a close second to America--and perhaps even ahead of it--in some areas of AI, widely considered vital to everything from digital assistants to self-driving cars.

Microsoft Corp. is setting up a new research lab focused on artificial intelligence with the goal of creating more general-purpose learning systems. The new lab, called Microsoft Research AI, will be based at the company's headquarters in Redmond, Washington, and involve more than 100 scientists from across various sub-fields of artificial intelligence research, including perception, learning, reasoning and natural language processing. The goal, said Eric Horvitz, the director of Microsoft Research Labs, is to combine these disciplines to work toward more general artificial intelligence, meaning a single system that can tackle a wide-range of tasks and problems. Such a system, for instance, might be able to both plan the best route to drive through a city and also figure out how to minimize your income tax bill, while also understanding difficult human concepts like sarcasm or gestures. This differs from so-called narrow AIs, which are just designed to perform a single task well -- for instance, recognize faces in digital photographs.

The Premier League is considering live-streaming matches online, a new report claims. Viewing figures hit a seven-year low last season, and bosses are said to be "weighing up" the idea of making games available to watch through a Netflix-style streaming service. The dip has largely been blamed on the rise of so-called "fully loaded Kodi boxes", but increasingly expensive ticket prices and TV packages, as well as changing viewing habits, are also key factors. The I.F.O. is fuelled by eight electric engines, which is able to push the flying object to an estimated top speed of about 120mph. The giant human-like robot bears a striking resemblance to the military robots starring in the movie'Avatar' and is claimed as a world first by its creators from a South Korean robotic company Waseda University's saxophonist robot WAS-5, developed by professor Atsuo Takanishi and Kaptain Rock playing one string light saber guitar perform jam session A man looks at an exhibit entitled'Mimus' a giant industrial robot which has been reprogrammed to interact with humans during a photocall at the new Design Museum in South Kensington, London Electrification Guru Dr. Wolfgang Ziebart talks about the electric Jaguar I-PACE concept SUV before it was unveiled before the Los Angeles Auto Show in Los Angeles, California, U.S The Jaguar I-PACE Concept car is the start of a new era for Jaguar.

It was a world-class stroke of good luck. An antique "typewriter" snapped up by an eagle-eyed expert in Romania for about $114 at a flea market turned out to be a rare Nazi Enigma cipher machine, CNN reports. The German Wehrmacht Enigma I sold for $51,500 to an anonymous bidder at an auction in Bucharest on Tuesday. During World War II, the German military used the machine to encrypt and decrypt sensitive messages. Depicted in the 2014 movie Imitation Game, dogged English cryptologists at Bletchley Park cracked the code, which the Germans believed unbreakable.

It is 10pm on Tuesday, and I have just become the 1,106,079th Spotify user this month to listen to an artist called Charles Bolt. The track I'm playing, Far and Beyond, is a gentle piano instrumental, not unlike the music Yann Tiersen composed for the soundtrack of whimsical French movie Amélie. This, I confess, is proving something of a problem. I have been listening to gentle piano instrumentals not unlike the music Yann Tiersen composed for the soundtrack of Amélie all day, and I suspect I reached the limits of my tolerance for it some hours back. This music long ago ceased to make me feel chilled or peaceful or any of the adjectives used in the titles of the Spotify playlists that contain it. Now I suspect it has turned me faintly hysterical.

The Word2Vec model has become a standard method for representing words as dense vectors. This is typically done as a preprocessing step, after which the learned vectors are fed into a discriminative model (typically an RNN) to generate predictions such as movie review sentiment, do machine translation, or even generate text, character by character. Previously, the bag of words model was commonly used to represent words and sentences as numerical vectors, which could then be fed into a classifier (for example Naive Bayes) to produce output predictions. Given a vocabulary of words and a document of words, a -dimensional vector would be created to represent the vector, where index denotes the number of times the th word in the vocabulary occured in the document. This model represented words as atomic units, assuming that all words were independent of each other.
