Collaborative Filtering under Model Uncertainty
Schmidt, Robin M., Hahn, Moritz
In their work, Dean, Rich, and Recht create a model to research recourse and availability of items in a recommender system. We used the definition of predictive multiplicity by Marx, Pin Calmon, and Ustun to examine different variations of this model, using different values for two model parameters. Pairwise comparison of their models show, that most of these models produce very similar results in terms of discrepancy and ambiguity for the availability and only in some cases the availability sets differ significantly.
Counterfactual Evaluation of Slate Recommendations with Sequential Reward Interactions
McInerney, James, Brost, Brian, Chandar, Praveen, Mehrotra, Rishabh, Carterette, Ben
Users of music streaming, video streaming, news recommendation, Offline evaluation is challenging because the deployed recommender and e-commerce services often engage with content in a sequential decides which items the user sees, introducing significant manner. Providing and evaluating good sequences of recommendations exposure bias in logged data [7, 16, 22]. Various methods have been is therefore a central problem for these services. Prior proposed to mitigate bias using counterfactual evaluation. In this reweighting-based counterfactual evaluation methods either suffer paper, we use terminology from the multi-armed bandit framework from high variance or make strong independence assumptions to discuss these methods: the recommender performs an action about rewards. We propose a new counterfactual estimator that allows by showing an item depending on the observed context (e.g., user for sequential interactions in the rewards with lower variance covariates, item covariates, time of day, day of the week) and then in an asymptotically unbiased manner. Our method uses graphical observes a reward through the user response (e.g., a stream, a purchase, assumptions about the causal relationships of the slate to reweight or length of consumption) [14]. The recommender follows the rewards in the logging policy in a way that approximates the a policy distribution over actions by drawing items stochastically expected sum of rewards under the target policy. Extensive experiments conditioned on the context. in simulation and on a live recommender system show that The basic idea of counterfactual evaluation is to estimate how a our approach outperforms existing methods in terms of bias and new policy would have performed if it had been deployed instead data efficiency for the sequential track recommendations problem. of the deployed policy.
3 Things to Consider When Setting Up Artificial Intelligence Team
Artificial intelligence (AI) is obviously a developing power in the technology business. Artificial intelligence is becoming the dominant center point at conferences and indicating potential over a wide variety of industries, including retail and manufacturing. New products are being incorporated with virtual assistants, while chatbots are responding to client inquiries on everything from your online office provider's website to your web hosting service provider's support page. In the interim, organizations, for example, Google, Microsoft, and Salesforce are incorporating AI as an intelligence layer over their whole tech stack. Indeed, AI is definitely having its moment. For organizations, practical AI applications can demonstrate in a wide range of ways relying upon your organizational needs and the business intelligence (BI) insights gained from the data you gather.
Google Assistant Snapshot offering YouTube Music playlists - 9to5Google
The Assistant feed has been available since March and continues to add new capabilities. This true Assistant successor to the original Google Now is now offering more Snapshot audio suggestions, including YouTube Music, and sports results. Back in June, Assistant Snapshot picked up a "Start listening for a fresh morning" card. This was solely aimed at offering "Podcasts for you." That card is now called "Perk up with fresh audio picks" to offer "News, podcasts, and music."
This week's best deals: Amazon Echo devices, iPad mini and more
If you aren't set to go back to school (either physically or remotely), a number of this week's sales can help. Amazon discounted a bunch of its Echo and Fire TV devices and you can get Apple's latest iPad mini for $50 off. A few TCL 8-series Roku TVs are half off, too, and you can stock up on some digital Nintendo Switch games in the company's latest eShop sale. These are the best deals from this week that you can still buy today. It's a good time to grab an Echo or Fire TV device now that Amazon has discounted most of them in its latest back-to-school sale.
Facebook is training robot assistants to hear as well as see
The algorithms build on FAIR's work in January of this year, when an agent was trained in Habitat to navigate unfamiliar environments without a map. Using just a depth-sensing camera, GPS, and compass data, it learned to enter a space much as a human would, and find the shortest possible path to its destination without wrong turns, backtracking, or exploration. The first of these new algorithms can now build a map of the space at the same time, allowing it to remember the environment and navigate through it faster if it returns. The second improves the agent's ability to map the space without needing to visit every part of it. Having been trained on enough virtual environments, it is able to anticipate certain features in a new one; it can know, for example, that there is likely to be empty floor space behind a kitchen island without navigating to the other side to look.
How Netflix uses AI for content creation and recommendation
That as a mind-set gets people narrowed. Netflix's core competency in data science enables the personalization of the streaming experience based on user behavior. Netflix classifies and tags content to get a nuanced view of consumer preferences. Netflix has developed over 1,000 tag types that classify content by genre, time period, plot conclusiveness, mood, etc. These tags help to define micro-genres, which, by 2014, had already reached 76,897.
Enbrighten Zigbee Plug-In Smart Dimmer review: Its hefty size is offset by its ability to control two lamps at once
Most smart-home owners dim lamps by screwing in smart bulbs, but plugging your lamps into a smart plug that supports dimming is an even easier solution. Plug-in smart dimmers aren't as ubiquitous as simple on/off smart plugs, but every major electrical manufacturer has one. This Enbrighten model from Jasco is based on Zigbee technology and so depends on a smart home hub that supports the same. That can be a Samsung SmartThings, a Hubitat Elevation, an Amazon Echo Plus, or a second-generation Echo Show, among others. As with its in-wall dimmer, however, the Enbrighten plug-in dimmer is not formally certified to work with SmartThings.
3 Huge Ways Companies Are Delighting Customers With Artificial-Intelligence-Driven Services
We know that the range of AI-loaded smart products is constantly expanding. But what's less obvious is how AI is also transforming the world of services – enabling service-based businesses to improve their offering, and even develop entirely new services and revenue streams that are underpinned by AI. Just as in product-based businesses, AI has become a driving factor for success in the service sector. Here are three ways businesses are delivering a better service through AI. AI provides incredible opportunities to get to know your customers – what they like and don't like, what they actually do (as opposed to what they say they do), how they engage with your service, what factors would encourage them to engage more deeply, and do on.
