Data preprocessing is an umbrella term that covers an array of operations data scientists will use to get their data into a form more appropriate for what they want to do with it. For example, before performing sentiment analysis of twitter data, you may want to strip out any html tags, white spaces, expand abbreviations and split the tweets into lists of the words they contain. When analyzing spatial data you may scale it so that it is unit-independent, that is, so that your algorithm doesn't care whether the original measurements were in miles or centimeters. However, preprocessing data does not occur in a vacuum. This is just to say that preprocessing is a means to an end and there are no hard and fast rules: there are standard practices, as we shall see, and you can develop an intuition for what will work but, in the end, preprocessing is generally part of a results-oriented pipeline and its performance needs to be judged in context.

Gaussian processes (GPs) provide a principled, practical, probabilistic approach to learning in kernel machines. GPs have received increased attention in the machine-learning community over the past decade, and this book provides a long-needed systematic and unified treatment of theoretical and practical aspects of GPs in machine learning. The treatment is comprehensive and self-contained, targeted at researchers and students in machine learning and applied statistics.The book deals with the supervised-learning problem for both regression and classification, and includes detailed algorithms. A wide variety of covariance (kernel) functions are presented and their properties discussed. Model selection is discussed both from a Bayesian and a classical perspective.

Machine translation (MT) systems such as Google Translate have become part of our daily life. But how do they work? In this talk, I'll explain how these systems are built. In the first part of my talk, I'll present a general overview of the field and the key ideas driving modern MT systems. In the second part, I'll dig deeper into the statistical techniques used to estimate translation models from data, and discuss some of the current hot topics in the field."

Bay Labs Inc. launched out of stealth mode today to use deep learning to help medical professionals in developing countries interpret ultrasounds so they can better treat heart disease. The company also announced a seed round of 2.5 million led by Khosla Ventures. Deep learning experts Yann LeCun, who serves as the director of AI Research at Facebook, and Nicolas Pinto and Jack Culpepper also invested. Bay Labs founder Charles Cadieu said ultrasound imaging presented the perfect problem to be solved with deep learning because it takes years of training to learn how to read ultrasound imaging. As ultrasound devices become cheaper and cheaper, they are increasingly available but especially in developing or rural areas, there may not be people trained to properly use the device or read the images.

Emerging technology makes possible use and management of group storytelling using artificial intelligence. By recognizing objects, and learning and reacting to speech patterns, artificial intelligence (AI) allows digital devices to assist us in our daily lives. In the near future, AI has the potential to significantly impact industry and business. Along with manufacturing and retail, both the energy and healthcare sectors are investing heavily in AI, in preparation for reaping the many benefits of this once unimaginable technology. As AI studies usage patterns, retailers and service providers will be able to learn about customers' use of their products and their preferences for new products. Medical clinics will diagnose health problems or read X-rays via smartphone.

The Friday afternoon information dump, a grand custom noticed by politicians and capitalists alike, is often presupposed to disguise unhealthy information. So it was a little bit bizarre that Elon Musk, founder of electrical automotive maker Tesla, and Sam Altman, president of famed tech incubator Y Combinator, unveiled their new synthetic intelligence firm on the tail finish of a weeklong AI convention in Montreal this previous December. However there was a cause they revealed OpenAI at that late hour. It wasn't that nobody was wanting. It was that everybody was trying. When a few of Silicon Valley's strongest firms caught wind of the venture, they started providing great quantities of cash to OpenAI's freshly assembled cadre of synthetic intelligence researchers, intent on maintaining these huge thinkers for themselves. The last-minute gives--some made on the convention itself--have been massive sufficient to power Musk and Altman to delay the announcement of the brand new startup.

BRUSSELS--Getty Images Inc., the world's largest photo agency, said Wednesday it has lodged an official complaint with the European Union's antitrust watchdog over Alphabet Inc.'s Google, accusing the U.S. technology giant of abusing its dominance in search to display copied images without compensation. The fresh complaint comes after the European Commission filed a new set of formal charges against Google last week for abusing its dominance with its Android mobile operating system to protect its search engine.

One of the advantages of running search workshops is that it forces me to keep up to date with changes and new developments. For many people, weird search results are something that they have to cope with but do not necessarily have time to investigate. They are providing information and support to other people, and once one project is over another takes its place. There is very little time to look into why the search engine - often Google - is behaving bizarrely. For me, keeping abreast of what the search engine companies are doing is a large chunk of my job and what I discover is sometimes disconcerting and worrying.
