In deep learning, one of the most widely-used technologies is TensorFlow, an end-to-end open-source platform for building models. It has a vast, flexible ecosystem of tools, libraries, and community resources. With the power of TensorFlow, researchers and developers can develop and deploy ML-powered applications.

In this tutorial, we’re going to work with TensorFlow.js, TensorFlow’s JavaScript library. We’ll use this library to learn to perform object detection—and specifically, detect instances of people—using our device’s webcam. The idea is fairly simple. We launch the camera in observation mode. Then, when it detects a human, it starts to record the movement of the person until the person is no longer in the view of the camera.

For this tutorial, you need a basic knowledge of React Native and some familiarity with Expo. You’ll also need the Expo client installed on your mobile device or a compatible simulator installed on your computer Instructions on how to do this can be found here.

We’ve seen a bunch of great use cases for on-device ML, but sometimes it’s easy for us to get a bit lost in the weeds. For many mobile developers, the idea of machine learning can sound scary—math, a steep learning curve, and questions about the need for machine learning features in the first place.

Mobile apps are made of screens that can vary in number depending on the app you’re developing. Handling user navigation can be tricky to learn and implement in mobile apps, but with dedicated open source libraries like react-navigation, the process becomes a lot easier.

React Navigation is a common library among React Native developers. It’s built with JavaScript, and you can create React components and apply any navigation pattern. On the device, it’ll provide a natural look and feel.

Nowadays, one issue that flies under the radar for Android developers is app security. Although the Android OS possesses a layer of security that’s sufficient most of the time, it can be enhanced by adding an extra layer of security using some advanced mechanisms and features.

Today’s article is going to cover some of these best practices and mechanisms to better secure your apps.

Generative adversarial networks (GANs) are among the more significant advancements in deep learning in recent years. Previously, we used machine learning and deep learning techniques with a considerable amount of data to build a model to understand data by classifying them. But now, with GANs, we use an algorithm that generates data for us.

Two of the most commonly used and efficient generative models are Variational Autoencoders (VAE) and Generative Adversarial Networks (GAN).

At some point, you might have asked yourself, What are the origins of parameters for artificial neural networks? What is the purpose of the weight? What if no bias is used?

In this tutorial, we set out to answer those questions by working from the most simple artificial neural network (ANN), to something much more complex. Let’s start by building a machine learning model with no parameters—which is Y=X.

In the landscape of new technologies that are capable of revolutionizing our daily lives, few are as tantalizing as facial recognition technologies. With all the recent controversy around Clearview AI, people are paying more and more attention to the technology, and they’re also eager to understand the how the tech works, and it’s limitations. This article won’t cover this ethical issue, but I’ll try my hand at explaining some facial recognition and detection techniques.

In a recent blog post, Facebook announced React Native version 0.62, and one of the top features of this release was a default integration of Flipper.

Flipper is an open source mobile debugging platform backed by Facebook. It is widely used by Android & iOS developers. Flipper’s simple and intuitive interface helps developers to visualise, inspect & control apps. It aims to be the number one companion for mobile app development.
