When you think about a Xamarin (or any cross-platform) application, performance is the most important consideration. Optimizing performance in a native app is a bit easier than with a cross-platform application, as there are hundreds of blogs and books and other resources to help you along the way. But there are less of these resources when it comes to apps developed with cross-platforms like Xamarin.

Research in computer vision has been booming over the past few years, thanks to advances in deep learning, increases in computing storage, and the explosion of big visual datasets. Every day, there are more computer vision applications in fields as diverse as autonomous vehicles, healthcare, retail, energy, linguistics, and more.
In this article, I’ll present the 5 major trends that have dominated computer vision research in 2018. An exhaustive review is impossible, so I’ll only share some of the accomplishments in the field that have most impressed me.
A few months back, as I was browsing through some fascinating projects on Augmented Reality, I came across an extremely intriguing project, which was one of the most artistic applications of AR I could think of. The final effects of the app looked something like this:
Cool isn’t it!? Go ahead and try out the awesome app for yourself.

One of the most crucial aspects of machine learning is understanding the mathematics & statistics behind it. In my journey to becoming a data scientist, I wanted to master not only the theoretical aspects of math & stats but also understand how I could apply them to my area of work.
There is an ever-increasing number of machine learning algorithms, and this post is going to focus on one of my favorites — the Naive Bayes algorithm. Specifically, I’m going to break this exploration into two parts—the first part is going to broadly cover the Naive Bayes algorithm and how it can be applied in text classification. And the second part of it is going to focus on building a REST API from the model we create in Part I. So stay tuned and enjoy!

The genetic algorithm (GA) is a biologically-inspired optimization algorithm. It has in recent years gained importance, as it’s simple while also solving complex problems like travel route optimization, training machine learning algorithms, working with single and multi-objective problems, game playing, and more.
Deep neural networks are inspired by the idea of how the biological brain works. It’s a universal function approximator, which is capable of simulating any function, and is now used to solve the most complex problems in machine learning. What’s more, they’re able to work with all types of data (images, audio, video, and text).

If you’re even remotely plugged into the tech world, you’d have been hard-pressed to miss a couple viral summer trends, both involving AI-powered photo transformations.
Here’s the gist. Snapchat caught fire and soared past all Q2 estimates, in large part because of their rollout out of popular gender-swap and baby-face Lenses. And soon after, FaceApp took the internet by storm when its old-age filter went viral. This has led to millions of users, including prominent celebrities, showing off what they’d look like in 40 years or as members of a different gender.
Very rarely do we find mobile apps that have no connection to a backend of any sort. There are many services and platforms like Azure or AWS, but one Google product stands out as well: Firebase. It’s easy to use, scalable and—most importantly—free. In this tutorial, we’ll explore how to connect our Flutter mobile app to Firebase.

Coil is a new image loading library in Kotlin for downloading images in Android, and it’s list of strengths are impressive:
Before Coil, we often used libraries like Glide and Picasso to download images in Android. But with the improvements that we’ll cover in this article, it’s clear that Coil is the go-to choice for Android devs working with Kotlin.

Many packages in Python also have an interface in R. Keras by RStudio is the R implementation of the Keras Python package. Most of the functions are the same as in Python. The only difference is mostly in language syntax such as variable declaration.
We live in the world with a vast array of mobile devices, primarily dominated by two platforms: iOS and Android. It’s a two-horse race, and I’m sure we can all agree on that. Building a mobile application for both platforms is not an easy task, though.
For iOS, you write code using Objective-C or Swift, and for Android, you will find yourself using Java or Kotlin. Apart from different programming languages used to create an app that can run on each of the two platforms, the toolchains are entirely different.
