Recommender system is a promising approach to boost sales to the next level by suggesting the right products to the right customers. This course starts by showing you the main solutions of recommender systems in the industry and the hypotheses behind the main solutions. You'll then learn how to build collaborative filtering models with fastai, and exercise the trained model on test datasets. As you advance, you'll visualize latent features, interpret weights and biases, and check what similar users/Items are from the model's perspective. Furthermore, you'll build a hybrid recommender system with popularity and association rule, and evaluate the recommendations with selected criteria.

As of this week, Tinder users will be able to run criminal background checks on their potential dates. The feature – launched in partnership with Garbo, a background check provider that aims to make public safety information more accessible – is intended to make Tinder users feel safer. But experts who specialize in sexual violence and surveillance have said the move is misguided, and risks amplifying the biases inherent in the criminal justice system. Background checks are blunt tools that gloss over some fundamental nuances, including that most people accused of sexual violence do not interact with the criminal justice system, said Albert Fox Cahn, the founder of the Surveillance Technology Oversight Project. Only 310 of 1,000 sexual assaults are reported to police, according to the anti-sexual violence organization Rainn.

The new $130 Echo Show 8 takes the top rank as the greatest Alexa smart display, with the Echo Show 10 being more novelty than necessity (that revolving screen doesn't support the $250 price tag). The second iteration of Amazon's mid-sized smart speaker with a display, which was released this month, combines some of the greatest features from the Show 10 (13-megapixel camera, digital zoom, and security camera functions) and compresses them into a more manageable size. The Echo Show 8 has a small enough footprint to sit on a bedside table or a kitchen counter. The Show 8 (available in Charcoal and Glacier White) offers the most bang (and screen size) for your buck, with a virtually identical design to its predecessor (same display, same speakers), but with a bit more behind the hood, including a new octo-core processing and a beefed-up camera. You can still watch shows, listen to music, control your smart home, send out announcements to your family, and check in on friends and family, but you can now zoom with a 13-megapixel camera.

The AI industry has major growth ahead, analysts say. The global artificial intelligence industry is expected to grow to $554 billion in total revenue by 2024, according to market research firm IDC. That amounts to some serious growth for an industry that generated revenue of $51.5 billion in 2021, according to market researcher Gartner. Virtually every industry is being disrupted by AI, automation and robotics. Whether it be machine learning, smart applications and appliances, digital assistants or autonomous vehicles, companies that aren't investing in AI products and services risk becoming obsolete.

Apple has quietly confirmed that the much-anticipated rollout of its iOS 15.4 update is coming sometime next week. It also includes 37 new emoji, including a pregnant man, a motorcycle tyre, a slide, a disco ball, a troll with a club, coral, kidney beans and a low battery. There's also a new'gender neutral' voice for its smart assistant Siri, called Quinn, recorded by a member of the LGBTQ community. Apple's confirmation follows the unveiling of new products on Tuesday, including the third generation phone in its'budget' iPhone SE line, starting at £419 ($429). Since the start of the pandemic, getting Face ID to automatically recognise our face to unlock our iPhones has been a bugbear as we've had masks over our faces.

Americans welcomed voice assistants into their homes on claims that Siri, Alexa and Google Assistant would be like quasi-human helpers, seamlessly managing our appointments, grocery lists and music libraries. From 2019 to 2021, the use of voice assistants among online adults in the United States rose to 30 percent from 21 percent, according to data from market research firm Forrester. Of the options, Siri is the most popular -- 34 percent of us have interacted with Apple's voice assistant in the last year.

In 2022, businesses will be using artificial intelligence (AI) in more innovative ways than ever before. Some of the most popular ways that AI will be used in businesses include: Chatbots will be used to communicate with customers. AI will be used to analyze data and make decisions. Robotics will be used to automate tasks. AI will be used to create new products and services. Virtual assistants will be used to manage tasks. AI will be used to improve customer service. Predictive analytics will be used to make decisions. It allows users to interact with digital objects using their smartphones. While mixed reality combines real world elements with virtual ones. These vehicles can drive on highways and through city streets without assistance from a driver or any human behind the wheel. They also protect organizations against malicious attacks. By 2030, this number is projected to grow to 3.1 billion. These people generate more than 70 percent of all greenhouse gas emissions and over 80 percent of global water usage.
