It seems like just about everything works with Alexa in some form or another, and the Echo Wall Clock is no exception. This timekeeper is Amazon's latest attempt to make everyday products easier to use--and it kind of succeeds at doing that. When using the clock, you can set multiple timers and reminders, and, instead of using your Amazon Echo speaker to keep track of how much time is left, you can see how much time remains when you look at the analog clock. That's because the Echo Wall Clock, which retails on Amazon for $29.99, has 60 LED tick marks that light up to show you how much time is left. It takes several minutes to get the Echo Wall Clock up and running, and you'll need an Echo speaker nearby to do so.

Amazon's first attempt at a set of true wireless earbuds gets a lot right, with Bose active noise reduction technology and hands-free Alexa. At £119.99, the Echo Buds undercut rivals, some of which cost more than twice as much. Their design is generic: large, kidney-shaped with a glossy touch panel on the outside and a standard silicone eartip on the inside. The eartip supports the earbud with the majority of the rest of the body sitting outside the ear. But the earbuds are large and heavy at 7.6g each, meaning they sit proud of your ear.

In 2019, smart speaker ownership in the U.S. surpassed 76 million, according to CIRP (Consumer Intelligence Research Partners), up from 66 million at the end of 2018. As voice-assistant technologies continue to advance in smartphones, smart speakers, and in vehicles, more consumers and businesses are exploring the benefits of using this technology to make tasks simpler. Tech giants like Amazon, Apple, Google, and Microsoft are all chomping at the bit, hoping customers will turn to their voice assistants for increasingly complex tasks. CIRP's research suggests Amazon is the current leader in smart speakers, with about 70% of the installed base being Amazon Echo devices, 25% being made up of Google Home devices, and 5% being made up of Apple HomePods. This remains relatively unchanged from the firm's previous year's research, with the exception of slight percentage growth from both Google and Apple in 2019 compared to 2018.

As Valentine's Day approaches and the aroma of love turns even devout singletons into frenzied love-seekers, many will invariably turn to dating apps for help. But caving in and venturing into the murky world of Hinge, Tinder and Bumble is a poisoned chalice, doomed to fail even if it works, a new study reveals. Academics have found people who have success in the fickle world of virtual swiping perceive themselves to be desirable as a result of their conquests. This sense of self-desirability, it has been proved, makes a person more likely to cheat when they eventually settle down into a serious relationship. Dr Cassandra Alexopoulos of the University of Massachusetts led the research and quizzed 395 participants on their dating app use.

The "Millionaire Matchmaker" star recently appeared on Us Weekly's "Hot Hollywood" podcast, where she claimed she's seen the 47-year-old actor on the elite dating app, Raya, on multiple occasions.

Artificial Intelligence (AI) is one of the wonders of the modern world, which isn't going to cease to amaze the most intelligent of human beings. Like other fields, the field of education is also gaining the maximum amount of benefits out of the promises of the AI-powered technology. The said transformation is not about science, technology, engineering, and mathematics, but is also relevant to the field of education as a whole. The whole industry of academia sees a transformation because of AI-powered tools and technologies. This article aims to spread a comprehensive level of awareness on the subject of the assistance of AI in the field of education.

The AI industry has been growing rapidly over the past few years, to such an extent that some now class it as an industry which has gone from "emerging" to one that has fully "emerged." As we enter 2020, it seems like the perfect opportunity to assess the industry as a whole. It is easy to forget just how quickly technology has advanced over the last 10 years. For instance, we take fingerprint and facial recognition for granted now as we do with so many other features when using our devices every day. However, at the turn of the last decade, social media was still in its infancy and many products, such as Amazon's Alexa, were still years away from being released.

Contextual bandit algorithms are applied in a wide range of domains, from advertising to recommender systems, from clinical trials to education. In many of these domains, malicious agents may have incentives to attack the bandit algorithm to induce it to perform a desired behavior. For instance, an unscrupulous ad publisher may try to increase their own revenue at the expense of the advertisers; a seller may want to increase the exposure of their products, or thwart a competitor's advertising campaign. In this paper, we study several attack scenarios and show that a malicious agent can force a linear contextual bandit algorithm to pull any desired arm $T - o(T)$ times over a horizon of $T$ steps, while applying adversarial modifications to either rewards or contexts that only grow logarithmically as $O(\log T)$. We also investigate the case when a malicious agent is interested in affecting the behavior of the bandit algorithm in a single context (e.g., a specific user). We first provide sufficient conditions for the feasibility of the attack and we then propose an efficient algorithm to perform the attack. We validate our theoretical results on experiments performed on both synthetic and real-world datasets.
