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.

Deep learning has seen tremendous progress over the past few years. This is largely due to the emergence of deep learning frameworks such as PyTorch and TensorFlow, which have greatly simplified even the most sophisticated research.

With smartphones having become the devices we use the most, the next wave of innovation is going to center on how we can leverage these rapid advances in deep learning to enhance our smartphone experiences. AI-powered mobile applications will become (and already are) smart enough to understand us and help us perform tasks via visual perception, language understanding, and voice recognition, even when not connected to the internet.

In a previous article, I discussed the possibilities of computer vision-based deep learning with both RNNs and CNNs.

Generally, ML engineers will specialize in one model architecture and let the other slide.

My point and purpose for writing this post is the following: learning both allows to tackle a wider range of use-cases.

Linear regression is an algorithm that finds a linear relationship between a dependent variable and one or more independent variables. The dependent variable is also called label and independent variables are called features as well.

Linear regression is one of the most foundational algorithms for statistical and machine learning analysis.

PyTorch is an open source machine learning framework introduced by Facebook in 2016. PyTorch is based on the Torch library, and it’s a Python-based framework as well. Apart from its Python interface, PyTorch also has a C++ front end.
