Beginners Guide to Artificial Intelligence! Deep Dive into AI
When a machine is intelligent, the Turing test is used in general. Simplified: A machine is to consider as intelligent, if its behavior (e.g. in chat-answers) is not distinguishable from a human being. A milestone in this context is the passing of the Turing Test of Google Duplex in May 2018. The further development of the Google Assistant arranged a hairdresser appointment without her counterpart noticing that she was talking to a machine on the phone. This is just the beginning.
Facebook updates Habitat environment to train 'embodied AI'
Where does your enterprise stand on the AI adoption curve? Take our AI survey to find out. In 2019, Facebook open-sourced AI Habitat, a simulator that can train AI systems embodying things like a home robot to operate in environments meant to mimic real-world settings, like apartments and offices. Today Facebook announced that it's extended the capabilities of Habitat to make it "orders of magnitude" faster than other 3D simulators available, allowing researchers to perform more complex tasks in simulation, like setting the table and stocking the fridge. Coinciding with this, Facebook collaborated with 3D space capture company Matterport to open-source what it claims is the largest dataset of indoor 3D scans to date.
The Use of Bandit Algorithms in Intelligent Interactive Recommender Systems
This can be naturally modeled constantly explore innovative ways to provide optimal online as contextual bandit problems (e.g., LinUCB [18] and Thompson user experiences for gaining competitive advantages. The great sampling [7]), where each arm corresponds to an item, pulling an needs of developing intelligent interactive recommendation systems item indicates recommending an item, and the reward is the instant are indicated, which could sequentially suggest users the most feedback from a user after the recommendation. Contextual proper items by accurately predicting their preferences, while receiving bandit algorithms have been widely applied in various interactive the up-to-date feedback to refine the recommendation results, recommender systems by achieving an optimal tradeoff between continuosly. Multi-armed bandit algorithms, which have been exploration and exploitation. Based on the preliminary studies [15, widely applied into various online systems, are quite capable of 18, 1], several practical challenges are identified in modern recommender delivering such efficient recommendation services.
Quantifying Availability and Discovery in Recommender Systems via Stochastic Reachability
Curmei, Mihaela, Dean, Sarah, Recht, Benjamin
In this work, we consider how preference models in interactive recommendation systems determine the availability of content and users' opportunities for discovery. We propose an evaluation procedure based on stochastic reachability to quantify the maximum probability of recommending a target piece of content to an user for a set of allowable strategic modifications. This framework allows us to compute an upper bound on the likelihood of recommendation with minimal assumptions about user behavior. Stochastic reachability can be used to detect biases in the availability of content and diagnose limitations in the opportunities for discovery granted to users. We show that this metric can be computed efficiently as a convex program for a variety of practical settings, and further argue that reachability is not inherently at odds with accuracy. We demonstrate evaluations of recommendation algorithms trained on large datasets of explicit and implicit ratings. Our results illustrate how preference models, selection rules, and user interventions impact reachability and how these effects can be distributed unevenly.
Echo Show 8 and Show 5 review: Not much has changed, and that's okay
I'll admit, I wasn't impressed when Amazon added a rotating base to the new Echo Show 10. Sure, the swiveling screen is useful for following you around the room during video calls, but it also felt gimmicky and unnecessary. Plus, it needs a lot of room to move around so you're losing a significant amount of counter space. That's why I'm glad the Echo Show 8 and 5 haven't repeated that design. In fact, Amazon has changed very little between this edition and the last, but trust me when I say that's a good thing. It's the Echo Show 8 that has seen the most changes, but most of those are under the hood: It now has a faster octa-core processor plus a much-improved 13-megapixel wide-angle camera (the previous model only had a 1-megapixel sensor).
'Alexa, let's read': Amazon's AI assistant can read books with your children, help them learn to read
Alexa wants to help your child learn how to read. With Amazon's new Reading Sidekick, kids can say "Alexa, let's read," to an Amazon Kids-enabled Echo device or the Amazon Kids app on a tablet and the artificial intelligence-powered assistant will take turns reading with them. An Amazon Kids subscription ($2.99 monthly) is required. Kids can choose from hundreds of physical and digital books that are supported, with more being added monthly. After asking Alexa to read with them, the AI assistant will ask how much do they want to read: a little, a lot, or taking turns.
Alexa can help your kids read stories
As good as it is to read with your kids, you might not always be there when they want to open a book. Amazon thinks it can fill in that gap, though. It just rolled out a long-teased Reading Sidekick feature that uses an Echo Kids device to help your kids read aloud on their own time. Children just have to tell Alexa "let's read" to take turns reading supported books, whether they're digital or physical. Your young ones won't always have to wait for you, in other words.
Amazon on AWS: Seamlessly integrating physical and emerging digital technologies
One area that personally fascinates me is how digital technologies are increasingly shaping the physical spaces around us, such as our homes and workplaces. Amazon Alexa is a great example of this--an on-demand AI assistant that exists in the cloud but that we can access with our voices to control the lighting in our homes, run our sprinklers, and lock our doors. This is the embodiment of our physical environment evolving due to enhancements provided by digital technologies. The natural language processing, machine learning models, speech synthesis, and all of the other complexity is performed in a digital system that sits beyond the walls of your home but is able to connect to that door lock and perform a physical action on your behalf. For an end user, the beauty of Alexa is that they don't have to know how any of this works, which parts are physical or digital; it just makes their lives better.
Amazon Echo Show 5 (2nd gen) review: The smallest Echo display gets a modest upgrade
Next, you can decide whether to allow other members of your household to view a live screen of the Echo Show's camera (more on that in a little bit) and whether to enable Amazon's Sidewalk neighborhood network (ditto). Finally, the display will also run a few free Prime trials by you before Alexa takes you on a brief tour. I've already covered the controls and button along the top edge of the Echo Show 5, but I'm going to highlight a couple of them: the mic mute button and the camera shutter. When you press mic mute, the Echo Show will both disable the microphone as well as electrically shut off the camera, while three visual indicators--a red line at the bottom of the screen, a "mute" icon in the corner of the screen, and a red light on the mic mute button itself--will let you know that Alexa can't see or hear you.
