Advances in Collaborative Filtering and Ranking

arXiv.org Machine Learning

In this dissertation, we cover some recent advances in collaborative filtering and ranking. In chapter 1, we give a brief introduction of the history and the current landscape of collaborative filtering and ranking; chapter 2 we first talk about pointwise collaborative filtering problem with graph information, and how our proposed new method can encode very deep graph information which helps four existing graph collaborative filtering algorithms; chapter 3 is on the pairwise approach for collaborative ranking and how we speed up the algorithm to near-linear time complexity; chapter 4 is on the new listwise approach for collaborative ranking and how the listwise approach is a better choice of loss for both explicit and implicit feedback over pointwise and pairwise loss; chapter 5 is about the new regularization technique Stochastic Shared Embeddings (SSE) we proposed for embedding layers and how it is both theoretically sound and empirically effectively for 6 different tasks across recommendation and natural language processing; chapter 6 is how we introduce personalization for the state-of-the-art sequential recommendation model with the help of SSE, which plays an important role in preventing our personalized model from overfitting to the training data; chapter 7, we summarize what we have achieved so far and predict what the future directions can be; chapter 8 is the appendix to all the chapters.

#artificialintelligence

The "The Business Use of Artificial Intelligence" training has been added to ResearchAndMarkets.com's offering. Your competitors are using AI to analyze sales, what do you do? Organizations today are applying artificial intelligence capabilities to a wide variety of uses especially in operations such as for process enablement. Each organization is focusing on performance improvements using AI. This explosion of interest in AI poses a challenge to managers to effectively make sense of and use AI effectively.


Robotic Revolution and different kinds of Robot? - Fukatsoft Blog

#artificialintelligence

Sci-fi movies have created an impact on our minds that using robots in our life is a very bad idea. From The Terminator to The Matrix, almost every Hollywood movie shows that robots took control over humanity. Even RUR, the 1920s Karel Capek play introduced the term "robot,". Despite the cinematic warnings robots have moved from fiction stories to an important piece of modern world arsenal. Now the developed world is also debating on the point to use develop killer robots and machine to save human life. In 1960, a company started building something that meets the guidelines of making a robot, that's when SRI International in Silicon Valley developed first truly perceptive and mobile robot known as SHAKY.


Deep learning won't detect fake news, but it will give fact-checkers a boost

#artificialintelligence

This article is part of our reviews of AI research papers, a series of posts that explore the latest findings in artificial intelligence. Fighting fake news has become a growing problem in the past few years, and one that begs for a solution involving artificial intelligence. Verifying the near-infinite amount of content being generated on news websites, video streaming services, blogs, social media, etc. is virtually impossible There has been a push to use machine learning in the moderation of online content, but those efforts have only had modest success in finding spam and removing adult content, and to a much lesser extent detecting hate speech. Fighting fake news is a much more complicated challenge. But they have limited reach.



Only AI can save us from a world of fakes (a world AI is also creating)

#artificialintelligence

The truth is out there. When I was a kid, my brother and I made a UFO out of paper plates, tin foil and marbles. Then we got on the roof with our spaceship dangling from a fishing line and, using our mom's plastic 110 camera, captured incontrovertible proof that we are not alone in the universe. But when everything went digital, creation and distribution both got easier, faster and more broadly distributed. And artificial intelligence (AI) will take it to a whole new level, enabling anyone to create perfect fakes of difficult-to-fake media, like video and audio.


109 Years of Short Film, 4K Resolution with Artificial Intelligence - Somag News

#artificialintelligence

A short film created by the employees of a Swedish company in 1911 was reconsidered by YouTuber named Denis Shiryaev. YouTuber succeeded in turning the short film into 4K 60 fps video with the artificial intelligence work applied to the short film in question. Artificial intelligence technologies are among the most popular initiatives of recent times. Artificial intelligence technologies, which can be used for both good and bad purposes, give life to tens of sectors again. As such, artificial intelligence technologies are closely followed by technology enthusiasts .


Musician uses computer algorithm to compose every melody that's possible in key of C

Daily Mail - Science & tech

A lawyer and hobbyist musician collaborated with a computer programmer to generate every possible 12-note melody in the key of C. The final compilation includes 68.7 billion melodic combinations, which the pair uploaded to the Internet Archive through a Create Commons Zero license, meaning they reserve no rights of ownership to any of them. A lawyer and hobbyist musician partnered with a programmer to create a computer algorithm to generate every 12-note melody possible in the key of C, leading to more than 68.7 billion combinations The project was originally started in 2019 when Damien Riehl, a lawyer and hobbyist musician, and programmer Noah Rubin were having drinks after a cybersecurity event. During the day's presentations Riehl had gotten the idea that it might be possible to'brute force' different combinations of musical notes in the same way that computer hackers brute force different letter and number combinations to crack passwords. At the time, a jury had just ruled against Katie Perry in a lawsuit brough by Flame, a rapper who claimed her chart topper'Dark Horse' had copied a musical fragment from his 2009 song'Joyful Noise.' The team was inspired by computer hackers how use a'brute force' combination technique to crack other people's passwords, and thought a similar approach might be useful for arranging notes into melodic structures Riehl and Rubin originally hoped to have an algorithm come up with every melodic combination of notes possible in western music, using the 88 notes of a standard piano as their starting point.


It's not you, it's them: Google, Alexa and Siri may answer even if you haven't called

USATODAY - Tech Top Stories

One in every four adults in America now owns a voice-activated smart speaker. While we love the convenience of talking to a gadget to play music, make calls, and such, most of us get a little creeped out when they "wake up" when they're not supposed to. I often trigger Siri when saying "seriously," or "Suli" – the name of my parents' dog. My friend Bill Keeshan says his Alexa connected device "gets triggered by my daughter saying'actually.'" All too familiar anecdotes aside, researchers at Northeastern University and the Imperial College of London spent the last six months streaming 125 hours of popular Netflix TV shows to a handful of voice-activated smart speakers.


Incredible footage of 1911 New York City is colorized by artificial intelligence in high resolution

Daily Mail - Science & tech

The 1911 video entitled'A Trip Through New York City' has been brought back to life more than a hundred years later by artificial intelligence. Shot by a Swedish film production company, the black and white footage has be restored with neural networks to create a colorized, sharper version of the black and white movie. The eight-minute clip transports viewers back in time to the Statue of Liberty, Battery Park, the New York Harbor and the famous Flatiron Building on Fifth Avenue. YouTuber Denis Shiryaev posted the new video on his site which is now in 4K quality at 60 frames per second. This'upscaled' footage was created using neural network-powered algorithms such as Topaz Labs' Gigapixel AI and DAIN.
