Federated recommendation systems can provide good performance without collecting users' private data, making them attractive. However, they are susceptible to low-cost poisoning attacks that can degrade their performance. In this paper, we develop a novel federated recommendation technique that is robust against the poisoning attack where Byzantine clients prevail. We argue that the key to Byzantine detection is monitoring of gradients of the model parameters of clients. We then propose a robust learning strategy where instead of using model parameters, the central server computes and utilizes the gradients to filter out Byzantine clients. Theoretically, we justify our robust learning strategy by our proposed definition of Byzantine resilience. Empirically, we confirm the efficacy of our robust learning strategy employing four datasets in a federated recommendation system.

Amazon is known to discount an Echo device every now and then, but now? The internet retailer is running a sale for many of its smart speakers, and in some cases they're steep bargains. The drops are sharp enough that they may be just what you need to get started on a smart home, or to finish a setup that might have been too costly before. The best deal may be for an Echo Studio (pictured above) bundled with a Philips Hue bulb -- you can buy it for $170, or $60 off. It clearly has the best sound quality of the Echo lineup, and it supports both high-resolution audio as well as home theater integration.

Whenever you look into any tech review or read articles on tech sites, they always make you believe that we're living among robots already and that AI (artificial intelligence) is already everywhere. It actually does already exist and you are interacting with AI. Do you sometimes ask Siri or Alexa something? What about that recommended movie on Netflix you've watched (btw. Hello and welcome back to another blog post, this time we'll figure out what AI is and what types of AI exist.

Google's announcement of its acquisition of Fitbit was taken to be a good sign for Google's not-so-exciting Wear OS and the absence of any hardware from the Mountain View-based tech giant. Now, it seems like that Fitbit hardware will also soon grace Google's ubiquitous Assistant. According to new evidence uncovered by 9To5Google within the Fitbit Android application, suggests that Google Assistant will soon be making its way to Fitbit devices. The code implementation is very similar to that of Amazon Alexa on the Fitbit Versa 2. With Alexa on the Versa 2, users could make use of the microphone to talk to their watch to control smart home devices or ask for information like the weather. Interestingly, according to a report by Wired UK, Fitbit had earlier reached out to Google about making the Assistant available on the Fitbit Versa 2. But according to the report, Google was "less willing than Amazon to make this happen". At the moment it's not clear whether the Google Assistant will be made available on the Fitbit Versa 2 or an upcoming Fitbit device.

Artificial Intelligence And Machine Learning Are More Important Than You Might Think For Mobile ... [ ] Devices AI is a common buzz word these days, but most consumers probably aren't aware how it's interwoven in their everyday lives. Some of us in the analyst and tech press communities may also scoff at how often the term is used for some technologies that hardly resemble true artificial intelligence. That said, there are a few platforms, beyond just powerful data centers, that are a natural for AI processing and the NNs (Neural Networks) that drive them. One of those is AI inferencing (using the AI to infer information, versus training an NN) at the edge, and in your pocket, with a smartphone. As you might imagine, smartphone platforms from Android to Apple vary greatly, but there are common workloads like speech-to-text translation, and recommender engines (like Google Assistant and Siri), that make heavy use of common AI NN models, and they do so on-device for speed and latency advantages.

The topic of artificial intelligence has become indispensable in today's world. More and more companies are developing innovative solutions that want to simplify people's lives with the help of machine learning, big data and digital assistants. Some players are particularly active here and invest considerable sums in AI and Co. We would like to introduce these to you below. When you think of artificial intelligence, you often imagine human-like robots that perfect human-machine interaction.

If you're one of the 60 million or so Americans who own a smart speaker – yes, that's about 1 in 4 adults – you already know the basics of these trendy hands-free gadgets. Enable the speaker with its "wake word" – such as saying "Alexa" for an Amazon Echo device ($29-up) – and then ask a question to receive an immediate answer in a friendly, human-sounding voice. The device can do things as simple as acting as a timer to delivering directions, traffic, recipes, music and podcasts, so it's easy to appreciate the value of an always-on virtual assistant. And hey, it's also cool to simply ask one to turn on the lights or turn down the temperature, and it just, well, works – if you have connected compatible devices, that is. Apple Notes:5 incredibly useful things you didn't know it could do You might be home a lot more and leaning on these smart speakers during the coronavirus pandemic, so here we examine a few lesser-known things you can do with your Alexa-enabled speaker.

Best Buy is making it easier than usual to outfit your home with smart displays. It's running a sale on Amazon's second-generation, 10-inch Echo Show that offers two units for the price of one, or $230. This could give you an easy way to video chat with distant family, a recipe guide in the kitchen or a bedside video viewer. The display quality of the second-gen model is merely average, but that big screen still makes it ideal for catching up on shows or checking information from afar. And more importantly, this Echo Show has surprisingly good sound quality -- in some ways, this is a quality Echo speaker that just happens to have a display.

"God made man because he loves stories." Elie Wiesel's phrase, taken from an ancient Hassidic parable, couldn't be more evocative. Nor could it be more capable of underlining that stories are intrinsically associated with the human condition. They accompany man's existence from the very beginning and are – perhaps – the best that humanity has to offer. The association between man and narrative dimension has deep roots.

The best soundbars achieve an almost perfect balance of aesthetics and performance. They eliminate the visual eyesore of speakers, amplifiers, and wires while delivering sonic performances that are vastly superior to any modern TV's sub-par audio. Relatively few reach that goal, leaving you to choose between an industrial design that will look attractive beneath your TV, and the type of audio presentation that will get your pulse pounding. Definitive Technology, a venerable name in high-end home theater and audiophile circles, comes very close to balancing those scales with its Studio Slim system, consisting of a svelte soundbar in a beautiful enclosure paried with a thundering wireless subwoofer and offered at price that won't take your breath away. It's not a smart speaker in and of itself, but you can control it using Google Assistant, and it also supports Google's Chromecast audio-streaming technology as well as Wi-Fi and Bluetooth.
