Each of these brand-name voice assistants speaks when spoken to, turning on a smart speaker or other voice-activated device that can answer questions. Voice is rapidly emerging as a hands-free medium consumers use for, well, just about anything -- music, news feeds, hints on removing stains, instructions for mixing cocktails. In homes, people use voice commands to adjust interconnected lights and thermostats, and search for -- and even buy -- products and services. Think of cave dwellers huddled around a fire pit enraptured by hunting tales, or a 1940s nuclear family gathered in front of a radio for the next episode of The Lone Ranger. And until recently, forms of entertainment and media that relied solely on voice seemed to be on the decline.

Two important problems in preference elicitation are rank aggregation and label ranking. Rank aggregation consists of finding a ranking that best summarizes a collection of preferences of some agents. The latter, label ranking, aims at learning a mapping between data instances and rankings defined over a finite set of categories or labels. This problem can effectively model many real application scenarios such as recommender systems. However, even when the preferences of populations usually change over time, related literature has so far addressed both problems over non-evolving preferences. This work deals with the problems of rank aggregation and label ranking over non-stationary data streams. In this context, there is a set of $n$ items and $m$ agents which provide their votes by casting a ranking of the $n$ items. The rankings are noisy realizations of an unknown probability distribution that changes over time. Our goal is to learn, in an online manner, the current ground truth distribution of rankings. We begin by proposing an aggregation function called Forgetful Borda (FBorda) that, using a forgetting mechanism, gives more importance to recently observed preferences. We prove that FBorda is a consistent estimator of the Kemeny ranking and lower bound the number of samples needed to learn the distribution while guaranteeing a certain level of confidence. Then, we develop a $k$-nearest neighbor classifier based on the proposed FBorda aggregation algorithm for the label ranking problem and demonstrate its accuracy in several scenarios of label ranking problem over evolving preferences.

In the next 10 minutes, you'll possibly be amazed, amused, blown away, frightened, or lost in thought. As this is the beginning of a new year and we'd all rather feel joyful – let's focus on the amusing part. Here are 8 mind-boggling technology acceleration outcomes awaiting for us in the (near) future. Artificial Intelligence (AI) by definition is an artificially created ability of a digital computer or computer-controlled robot to perform tasks commonly associated with intelligent beings. AI could carry out a complete simulation of the human brain and even exceed it.

Apple is going to update its AirPods this fall, introducing new noise cancelling technology and a price point that's $60 higher than the previous version. The new model of the wireless earbuds could arrive as soon as the end of the month, and will be branded as AirPods Pro. The Pro version of the earbuds will retail for $260, while the current non-Pro version of will continue to sell for $199. According to Cnet, the addition would leave Apple selling two different noise-cancelling headphones this fall, following on the announcement of Beats Solo Pro earlier this week. The new AirPods were first discovered by Guilherme Rambo of 9to5Mac as he was looking for secrets in the code of the recent iOS 13.2 update.

"Mia" is the virtual assistant introduced by Australian digital bank Ubank in February 2019. These aren't the members of a new, all-female rock group, but names that several large banks have been giving to their automated digital assistants. So-called chatbots have become a useful cost-cutting tools for companies with large subscriber bases (think banks, insurance firms and mobile phone operators). As they replace human call-center workers, such bots will help save banks an estimated $7.3 billion in operational costs by 2023, Juniper Research predicts. But the proliferation of bots with female names raises questions about whether they might also perpetuate gender stereotypes, particularly around the notion of women in the role of assistants.

As far as the impact of AI and Machine Learning on the modern world is constantly growing and changing every industry - from Education to Robotics and Heavy machinery, there is no doubt that tomorrow will be revolutionized by these two areas of computer science. Many cutting-edge inventions have already been made so far: Personal Assistants with a high level of human language understanding as Siri and Alexa, self-driving Tesla cars, IBM's Watson (won against 2 best performers at the Jeopardy show), autonomous weapons, dancing NAO Robots (2010 World Expo) and more. Numbers talk louder then simple words, so let's take a look at some predicted statistics of AI in business for next 5 years: By 2025 the whole AI market that was only $1.6 billion 4 years ago, will be around $60 billion and the world's GDP will rise by $15 trillion before 2030 because of AI. The intensively rising number of AI startups has been noticed since last two decades - at about 14 times more, than it was, and equivalently the amount of investments in this area also grew almost 6 times. Data Scientists from Google assume that only in the next year(2020) robots will manage to imitate complicated human behaviour and emotions like flirting or making fun of somebody.

From machine learning and AI right through to securing the IoT, here are five things we learned about at this year's event, which took place in Lisbon on October 14. Have you ever thought about how many decisions machines have made today? Or how many of those decisions were based on gender, race, or background? Chances are you don't even realize just how many decisions are made by artificial intelligence instead of a human. Kriti Sharma, Founder of AI for Good, explained that algorithms are being used all the time to make decisions about who we are and what we want.

Right now you can get the Google Assistant to start listening to you with a button push, or by saying "hey Google", or by squeezing the sides of your phone – but the Pixel 4 series is being tipped to introduce a new way of activating the app. According to 9to5Google, a new'raise to talk' option is in development, where you only need to lift up your phone and start talking to use Google Assistant. The voice interaction will need to happen right after you lift the phone, apparently, and the necessary voice match processing is carried out on the device itself – so other people won't be able to get at the feature just by picking your phone up. However, it's not certain that'raise to talk' for Google Assistant will be ready in time for the Pixel 4 launch on October 15 – it might be that the functionality gets pushed out as an update at a later date. We know that an improved Google Assistant is on the way, because Google showed off some of its features – including a more intuitive way of continuing a conversation with the app – at the Google IO event back in May.

Almost everyone with a personal computer carries a piece of artificial intelligence (AI) interface in the form of Siri or Cortana. If not, you might have interacted with one on your smartphone today. These are the most common touchpoints between consumers and AI. Needless to say, that is just the tip of the iceberg. AI penetration has been impactful in B2B setups or at the back-end of many services that we use every day.
