The Amazon Echo can seem like your best friend--until it betrays you. That's because this device is different from anything else in your house. Alexa, the voice assistant that powers Echo and more, is always listening, sending what you say after using a "wake" word to Amazon's servers. Of course, Echo isn't the only voice-assistant speaker on the market, but it sits in millions of homes, and Alexa is headed to devices from companies like Ford, Dish, Samsung, and Whirlpool.

Machine learning has long powered many products we interact with daily - from "intelligent" assistants like Apple's Siri and Google Now, to recommendation engines like Amazon's that suggest new products to buy, to the ad ranking systems used by Google and Facebook. More recently, machine learning has entered the public consciousness because of advances in "deep learning" - these include AlphaGo's defeat of Go grandmaster Lee Sedol and impressive new products around image recognition and machine translation. In this series, we give an introduction to some powerful but generally applicable techniques in machine learning. These include deep learning but also more traditional methods that are often all the modern business needs. After reading the articles in the series, you should have the knowledge necessary to embark on concrete machine learning experiments in a variety of areas on your own.

Elliptic Labs says it can use the speakers and mics on smart home assistants to detect a person's presence.

One of the great horrors of Windows 10 is that Microsoft forces you to use Bing and Microsoft Edge with Cortana. When you search with Cortana, any web searches are automatically sent to Bing and displayed in the Edge browser, no matter what your default browser is. Before April 2016 you could use any browser you wanted, although Cortana still insisted on Bing for search. But then Microsoft put a stop to browser choice, and Cortana-loving Edge haters have been recoiling ever since, until now. Norway-based developer Daniel Aleksandersen recently created a program called EdgeDeflector that puts a stop to Cortana's shenanigans.

If you've been waiting for Google to bring its smart Home speaker to the UK, you may only have to hang on a little bit longer. A Google spokesperson confirmed to Engadget today that the contoured cylinder will make its journey across the Atlantic in the second quarter of this year, giving the Amazon Echo some much-needed competition in the process. Details are scarce right now but Rick Osterloh, Google's SVP of Hardware, told BBC reporter Rory Cellan-Jones that he believes the Home's "AI skills and vast data" will give it the edge over its rival. The Echo has been on sale in the UK since September 2016 and has already gained support from various local apps and services, which may put it slightly ahead of Google's offering at launch. As for release date and price, Google will provide more information in the near future.

Mobile World Congress 2017 -- Telef--nica has taken a bold leap into the age of artificial intelligence with its launch today of a new digital assistant called Aura, which appears to be the product of a two-year research initiative at the Spanish telco that has been a closely guarded secret. Unveiled in Barcelona on the cusp of this year's Mobile World Congress, Aura sounds and works much like Apple Inc. (Nasdaq: AAPL)'s Siri or Amazon.com Inc. (Nasdaq: AMZN)'s Alexa, allowing customers to check on details of their Telef--nica service -- and ask for problems to be resolved or new features to be provided -- using a voice interface on a mobile device. Judging by the demonstration at Telef--nica's offices in Barcelona, Aura works at least as effectively as the digital assistants developed by the web giants but differs in one important respect: It stores and can act upon all of the information about a particular user that is relevant to his or her relationship with the operator. In fact, Telef--nica balks at the "digital assistant" label, preferring to think of Aura as a "cognitive intelligence" system than a neat bit of voice-recognition software.

The most basic and well known application of NLP is Microsoft Word spell checking. Text analysis, also known as sentiment analytics is a key use of NLP. Businesses are most concerned with comprehending how their customers feel emotionally and use that data for betterment of their service. Email filters are another important application of NLP. By analyzing the emails that flow through the servers, email providers can calculate the likelihood that an email is spam based its content by using Bayesian or Naive based spam filtering.

Universities will get £17m to help them develop pioneering robotics and AI as part of the plans to support the'booming' sector, which is behind smartphone voice and touch recognition technology and digital assistants such as the iPhone's Siri. AI also forms the bedrock of video games and music and film recommendations services, as well as improving online customer services, and is used in fraud detection tools used by banks. Among the projects supported with the money from the Engineering and Physical Sciences Research Council (EPSRC) is a move by the University of Manchester to develop autonomous robots for hazardous environments such as nuclear facilities. Researchers at Imperial College London will use some of the funds to try and make advances in the field of surgical micro-robotics. A major review of AI will also be carried out by Professor Dame Wendy Hall, Regius Professor of Computer Science at the University of Southampton, and BenevolentTech chief executive Jerome Pesenti.

On February 9, 2017, two technology market leaders made announcements: SAP unveiled its next-generation intelligent ERP system, and Nvidia announced that demand for artificial intelligence (AI) applications was driving demand for its graphics platform. On the face of it, these announcements were business as usual – routine sound bites that proliferate in the tech news landscape. Look a bit deeper, though, and you realize that this day marked a profound shift in both the way businesses use technology and the implications for the rest of us. For decades, developing a computer that could think has been the Holy Grail of technology. And while we have made tremendous progress in our ability to process vast amount of data, the "thinking" part has remained mostly elusive. We are still stuck between two diametrically opposed visions of AI – on one side, it's the smart but deeply dystopian world of HAL ("2001: A Space Odyssey") and on the other, it's a simpler world of devices like Alexa or Siri playing songs or ordering items for us.

Sony Corp. and Line Corp., Japan's most popular messaging service, are considering joining forces to develop devices powered by artificial intelligence. The companies are exploring opportunities around digital personal assistant technology to co-create a new communication experience, Sony said in a statement at the Mobile World Congress in Barcelona, Spain, on Monday. Sony unveiled concept earphones powered by Xperia Agent, a virtual butler that responds to voice commands and head gestures. While Sony's Xperia smartphones are an also-ran in a market dominated by Apple Inc. and Samsung Electronics Co., Chief Executive Officer Kazuo Hirai has resisted pressure to shutter the mobile business. He argues it will serve as a springboard into the nascent market for wearable and interconnected devices known as the Internet of Things.
