What makes Bach sound like Bach? MusicNet is a new publicly available dataset from UW researchers that labels each note of 330 classical compositions in ways that can teach machine learning algorithms about the basic structure of music.Yngve Bakken Nilsen, flickr The composer Johann Sebastian Bach left behind an incomplete fugue upon his death, either as an unfinished work or perhaps as a puzzle for future composers to solve. A classical music dataset released Wednesday by University of Washington researchers -- which enables machine learning algorithms to learn the features of classical music from scratch -- raises the likelihood that a computer could expertly finish the job. MusicNet is the first publicly available large-scale classical music dataset with curated fine-level annotations. It's designed to allow machine learning researchers and algorithms to tackle a wide range of open challenges -- from note prediction to automated music transcription to offering listening recommendations based on the structure of a song a person likes, instead of relying on generic tags or what other customers have purchased. "At a high level, we're interested in what makes music appealing to the ears, how we can better understand composition, or the essence of what makes Bach sound like Bach. It can also help enable practical applications that remain challenging, like automatic transcription of a live performance into a written score," said Sham Kakade, a UW associate professor of computer science and engineering and of statistics.

The social media company has been embroiled in a number of content moderation controversies this year, from facing international outcry after removing an iconic Vietnam War photo due to nudity, to allowing the spread of fake news on its site. Facebook has historically relied mostly on users to report offensive posts, which are then checked by Facebook employees against company "community standards." Decisions on especially thorny content issues that might require policy changes are made by top executives at the company. Candela told reporters that Facebook increasingly was using artificial intelligence to find offensive material. It is "an algorithm that detects nudity, violence, or any of the things that are not according to our policies," he said.

You've seen it in the movies: super smart robots finally come to the conclusion that we humans are making a mess of things. Still think that's the stuff of science fiction? We're building machines that are smarter than we are, that can do our jobs for us, and that we will very soon come to depend on to maintain our technology-saturated lifestyles. With so much going on in the world of AI, we are becoming all but desensitized to the technology. So let's pause for a moment and look at the slightly creepy, but really cool advances taking place in AI today.

Though movies and TV shows would have us believe that artificial intelligence means machines rising up against us, the truth is much more benign. Indeed, many of us use AI on a regular basis: Just ask Siri for directions to a restaurant or tell Shazam to name a song. This is certainly true of Facebook too, which uses AI and machine learning for a variety of tasks such as identifying images, translating languages and, yes, ranking your News Feed. With such a vested interest in AI, Facebook is releasing a series of videos today to offer a brief introduction to what it is and how it works. "We want to tell people it's not magic," says Yann LeCun, Facebook's director of AI research.

Publishing is no longer about writing just a book. Therefore publishing is not just dependent on itself but on other mediums as well. A best selling book makes it to a Netflix show or a movie and that in turn gives the book sales another fillip. So content in its traditional form - i.e as a book is not dying anytime. In fact, the need for good content is greater than ever as players like Netflix and HBO keep on searching for the next bestselling story to be made into a tv show or a movie.

Episode 9: For the past five years, Russia's been building walls around its web and packing it with tech oligarchs, startup cities, face-finding algorithms, hacker hunters, and, of course, a few bears. The best mouse I've ever met lives in Akademgorodok, a Siberian city about an hour's drive from Novosibirsk. The mouse is not alive. It's a 2-foot statue that stands watch over a genetic engineering laboratory. Frozen in time, the mouse wears glasses and a lab coat, using a pair of knitting needles to stitch together strands of DNA.

Artificial intelligence is getting its teeth into lip reading. A project by Google's DeepMind and the University of Oxford applied deep learning to a huge data set of BBC programmes to create a lip-reading system that leaves professionals in the dust. The AI system was trained using some 5000 hours from six different TV programmes, including Newsnight, BBC Breakfast and Question Time. In total, the videos contained 118,000 sentences. First the University of Oxford and DeepMind researchers trained the AI on shows that aired between January 2010 and December 2015. Then they tested its performance on programmes broadcast between March and September 2016.

It's no secret that the new "Power Rangers" film is a departure from the original TV series, and the concept art for the movie's new Alpha 5 serves as further confirmation. Even fans who thought the updated looks for Rita, the Rangers' suits and the Zords gave them adequate mental preparation for any other redesigns probably couldn't refrain from a quick "Ay yi yi yi yi" after seeing the new Alpha. Revealed by IGN, this new take on the Power Rangers ally is more than a bit of a departure from the character's original look. In the TV series, Alpha was Zordon's panicky but devoted robotic assistant who served as the Rangers' advisor and friend. While the new Alpha retains the gold saucer-shaped helmet as well as the red body, not much else is recognizable.
