Images add another dimension to a mobile app. User-generated images amplify that.
If you’re building a React Native app, how do you give your users the ability to upload images? React Native has polyfills for many web APIs — to do image uploading we’ll be using the fetch API.
Before we can actually start uploading images, we’ll to create two projects:
In a previous tutorial, I introduced the Kivy Python framework as a tool to run NumPy (Numerical Python) on Android. As a brief refresher, Kivy is a cross-platform framework for building natural user interfaces (NUIs). It’s very simple to learn and then use iteratively. The same code, unchanged, can run on Linux, Windows, Mac, iOS, and Android.

Have you ever wanted to make your own augmented reality app, but don’t know where to start? Or, are you just interested in AR technology more broadly?
In this series, we’ll demonstrate how to use Unity’s game engine to make a small AR app that can demonstrate important principles of the technology. To do so, we’ll dive deep in to Unity’s AR Foundation framework.

React Native, when used with Expo as a toolchain, eases the common pain points in managing iOS and Android applications. After saying that, I realized that there’s a delight in using this ever-growing open source mobile application framework.
Expo has gained a lot of credibility as a framework that provides collective solutions for building React Native applications by lowering the time and effort of developers using it. They’re continuing to enhance it from time to time to keep up with the latest changes in React Native community. That said, Expo SDK33 is a blast.

Have you always wanted to make a game but don’t know where to start? Or are you just interested in game technology?
In this article series, we’ll demonstrate how to use Unreal Engine 4 to make a side-scroller game and package it for Android. This game will have various elements like collecting pickups/coins, a health system, and also enemy AI. If you’ve played Mario in past then you’ll love it. We’ll try to build our game along those lines only— even if you don’t have any prior programming experience.

Filter methods select features from a dataset independently for any machine learning algorithm. These methods rely only on the characteristics of these variables, so features are filtered out of the data before learning begins.
These methods are powerful and simple and help to quickly remove features— and they are generally the first step in any feature selection pipeline.

Hello readers! I will be discussing some cool stuff here, today. So, just wear some black goggles and follow along.
Of the modern world’s technological advancements, I’d argue that, most elegant of them all, are the strides we’ve made in allowing computers to have the power of human-like perception.
Yes, This brilliant idea of training a computer so that it learns like a human, behaves like a human, acts like a human, always seemed distant. But now, through advancements in neural networks and computational power, the dream is real.
This article is all about variable discretization, which is the process of transforming a continuous variable into a discrete one. It essentially creates a set of contiguous intervals that span the variable’s value range.
Binning is another name for discretization, where the bin is an alternative name for the interval.
There are multiple approaches to achieve this discretization. In this guide, we’ll explore the following methods:

This article is the final part of our series covering techniques for feature selection in machine learning models. Since this is the end, I’d recommend circling back and checking out the rest of the articles in the series:
This post will be covering several advanced techniques for feature selection.
Dimensionality reduction isn’t quite the same as feature selection, even though both try to reduce the number of features. While feature selection selects and excludes some features without making any transformation, dimensionality reduction transforms features into a lower dimension.

The steady rise of mobile Internet traffic has provoked a parallel increase in demand for on-device intelligence capabilities. However, the inherent scarcity of resources at the Edge means that satisfying this demand will require creative solutions to old problems. How do you run computationally expensive operations on a device that has limited processing capability without it turning into magma in your hand?
