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.
6 Python Projects You Can Finish in a Weekend
Learning Python can be difficult. You might spend a lot of time watching videos and reading books; however, if you can't put all the concepts learned into practice, that time will be wasted. This is why you should get your hands dirty with Python projects. A project will help you bring together everything you've learned, stay motivated, build a portfolio and come up with ways of approaching problems and solving them with code. In this article, I listed some projects that helped me level up my Python code and hopefully will help you too.
Framework for A Personalized Intelligent Assistant to Elderly People for Activities of Daily Living
Thakur, Nirmalya, Han, Chia Y.
The increasing population of elderly people is associated with the need to meet their increasing requirements and to provide solutions that can improve their quality of life in a smart home. In addition to fear and anxiety towards interfacing with systems; cognitive disabilities, weakened memory, disorganized behavior and even physical limitations are some of the problems that elderly people tend to face with increasing age. The essence of providing technology-based solutions to address these needs of elderly people and to create smart and assisted living spaces for the elderly; lies in developing systems that can adapt by addressing their diversity and can augment their performances in the context of their day to day goals. Therefore, this work proposes a framework for development of a Personalized Intelligent Assistant to help elderly people perform Activities of Daily Living (ADLs) in a smart and connected Internet of Things (IoT) based environment. This Personalized Intelligent Assistant can analyze different tasks performed by the user and recommend activities by considering their daily routine, current affective state and the underlining user experience. To uphold the efficacy of this proposed framework, it has been tested on a couple of datasets for modelling an average user and a specific user respectively. The results presented show that the model achieves a performance accuracy of 73.12% when modelling a specific user, which is considerably higher than its performance while modelling an average user, this upholds the relevance for development and implementation of this proposed framework.
