A lot of people have been doing light therapy during the winter to keep their mood up while the Sun is hiding. There was even an episode of Broad City about it. Well, Llana could have used the Luminette 2 light therapy glasses, because they let you get some much-needed light while you're on the go instead of dashing into a room for light therapy every time your mood goes down. These are for the person who has issues with seasonal depression who doesn't have a lot of time. There are so many different headphone options out there that it's hard to know which ones to get, so we'll save you some time.

In Yana Welinder's house, her son will say "Papa' to either her or her husband. But her child, who just turned 1, does have a name for another prominent figure in the household: "Aga." Or, as the rest of us know her, Alexa -- Amazon's voice assistant. Welinder's son can't summon the assistant from the Echo speaker in their San Francisco home on his own. But he knows what he's trying to do.

Displays for the echo dot and echo are seen inside the Amazon Books store in the Time Warner Center at Columbus Circle in New York City, New York, U.S., May 25, 2017. The smart speaker is the newest home consumer electronics product category. And this year, the technology is more advanced with features like built-in displays. Fox News spoke with DealNews, a comparison shopping website, for recommendations on the best deals for smart speakers, based on a voice-controlled intelligent personal assistant such as Amazon's Alexa. Here are five of the best deals for this holiday shopping season.

Just as the Amazon Echo appears poised to maintain its dominance of the voice-activated connected intelligence device category, it's now ready to make another leap in that space by adding a screen to the mix. Pre-orders for the $299 Echo Show began less than a week ago, but it already is a top-selling electronics device (on Amazon, naturally). Promising consumers "everything you love about Alexa," Amazon says "now she can show you things: Watch video flash briefings and YouTube, see music lyrics, security cameras, photos, weather forecasts, to-do and shopping lists, and more. The influence of voice-activation and connected intelligence is already threatening to up-end traditional advertising and even calls into question the value of a website, as Birchbox CEO Katia Beauchamp has opined. Does Amazon Echo Show's video and touchscreen device further alter expectations among consumers and brands?

The first sale we've seen on the upgraded model of the Echo.The 2nd Generation Amazon Echo is our pick in our guide to the best Alexa-compatible smart-home devices for Amazon Echo. We wrote, "An Amazon Echo offers a convenient interface for your smart home and provides functionality that an app on your phone can't. If you already have some Alexa-compatible devices or one of the three major smart-home hubs (SmartThings, Wink, or Insteon), adding an Echo can make accessing those devices more interesting and convenient."

Amazon Echo and Google Home--and other devices that have Alexa and Google Assistant built in--are some of the most promising new technologies to come along in years. And they're genuinely useful to have around, whether it's to settle a bet or help out with a recipe. But it can also feel a little creepy to have a speaker in your house that's always listening. What exactly is it doing with that info? While their microphones are always on, Google Home and Alexa don't actually do anything with your voice until you say their "wake word," which is usually just'OK Google' or'Alexa'.

While we don't celebrate Thanksgiving, we're now fully onboard with the sale frenzy that accompanies it (even if we don't like to admit it to ourselves). If you're in the market for a new piece of tech but don't fancy wading out onto the High Street, we've got you covered. As always, if you spot anything that we might have missed, drop us a note in the comments below and we'll add it to our list as soon as possible. Some will be daily deals, so move quickly. They are targeted at Brits mind you, so we're avoiding anything that forces you to pay in dollars (you can find that here), Euros or any other (probably stronger) currency.

The Amazon Echo Show takes the Alexa voice assistant and squeezes it into a cross between a digital photo frame, small TV and smart speaker for something that's more than just an interesting novelty. The Echo Show is effectively what you get if you took an Alexa-integrated Fire tablet, put a powerful speaker on the bottom and framed it with glossy black plastic. The result is a rather monolithic look. For such a small thing it looks fairly imposing, and has split opinion of visitors to my house 50:50 on whether it's attractive, but placed in a corner or on a shelf, it can easily blend in with the surroundings. In fact, when it's not actively doing something, the Echo Show can operate like a smart, internet-connected version of those digital photo frames that quickly went out of fashion.

We study platforms in the sharing economy and discuss the need for incentivizing users to explore options that otherwise would not be chosen. For instance, rental platforms such as Airbnb typically rely on customer reviews to provide users with relevant information about different options. Yet, often a large fraction of options does not have any reviews available. Such options are frequently neglected as viable choices, and in turn are unlikely to be evaluated, creating a vicious cycle. Platforms can engage users to deviate from their preferred choice by offering monetary incentives for choosing a different option instead. To efficiently learn the optimal incentives to offer, we consider structural information in user preferences and introduce a novel algorithm - Coordinated Online Learning (CoOL) - for learning with structural information modeled as convex constraints. We provide formal guarantees on the performance of our algorithm and test the viability of our approach in a user study with data of apartments on Airbnb. Our findings suggest that our approach is well-suited to learn appropriate incentives and increase exploration on the investigated platform.

We talk about artificial intelligence (AI), robots, and machine learning as if they're coming soon, or are just some tech pipe dream. In fact, a special report from Bank of America, Merrill Lynch predicts the global market for AI and robots will be just under $153 billion by 2020, and some industries will experience up to a 30% productivity increase through the use of those technologies alone. That can either terrify you if you've seen too many sci-fi films, or excite you if you consider the upside and benefits it could yield. The reality probably lies somewhere in the middle. There will be disruption – there will be jobs and perhaps even whole industries that see massive displacement from robots and other "intelligent" machines. And that says nothing of the inherent risk associated with creating something capable of logical thinking without emotion. The robots may not rise up and exterminate humanity any time soon, but the development of true AI is closer than you think.
