To kick things off with this tutorial on how to build you own recommender systems in Python, we’ll learn how to make an e-commerce item recommender system with a technique called content-based filtering.

Unfortunately, as of the day of this post’s publication, Wikipedia defines recommender systems too narrowly, as “a subclass of information filtering systems that seeks to predict the ‘rating’ or ‘preference’ that a user would give to an item”. Recommender systems are much more than this definition.

Face Effects allow you to make alterations to faces in Lens Studio. Face effects can be used to make subtle changes on the face, exaggerated changes such as bulging of the face, and you can even add art and art objects to the face. These face effects include eye color, face stretch, face liquify, and more. Let’s look at these face effects in more depth.

Recently, Google released the first stable version of the androidx.biometric library, which allows developers to use the BiometricsPrompt to bring a standardized experience for fingerprint authentication and potentially fewer bugs when the developers implement it from scratch.

In API 28, the FingerprintManager was deprecated and BiometricPrompt came into the picture. It shows a system-provided dialog upon starting the authentication, unlike the FingerprintManager class where the developer had to design the UI for the fingerprint dialog, manage its state, add custom error handling, use 3rd party libraries which can handle fingerprint authentication for you, and more—in other words, a lot

Augmented reality (AR) and artificial intelligence (AI) are two of the most promising technologies available to mobile app developers. Huge hype cycles and rapidly evolving tools, though, have blurred the lines between the two, making it difficult to tell where AI ends and AR begins. This post aims to disambiguate AR and AI. It covers how AR and AI work together, the current state of SDKs and APIs for each, and some practical ways to combine them to build incredible mobile experiences.

In this project, we’ll use the react-native-maps and react-native-background-geolocation package, a group of React Native map components for iOS + Android that we’ll use to configure a React Native location tracking application.

Here, we’ll focus on building the tracking app project for iOS. The library ships with platform native code that needs to be compiled together with React Native. This requires you to configure your build tools.

Artificial intelligence (AI) is a buzzword you see pretty much everywhere around you, even when you’re not looking. It has completely dominated tech media, newsrooms, and is even credited with the success of many modern applications.

But does it really work, or is it just hype? Truth is, it does. While there might be some hype around its capabilities, AI has been demonstrated both in research and industry to work really well for a variety of tasks and use cases.

With the immense growth of videos on the internet, it’s become really difficult to efficiently search amongst millions of them. When searching for an event query, users are often bewildered by the vast quantity of videos returned by search engines like Google. Exploring such results can be time-consuming and can also degrade the user experience.

Hence, we’ll be discussing ways to automate this process with machine learning-based video summarization techniques.
