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.

Hello everyone! My name is Yuma Soerianto. Today, I’ll show you how to make a simple Augmented Reality game using Apple’s ARKit framework and Xcode.

This is a finished product of what we’re going to build. It’s a simple game where you shoot and knock down crates.

In the last post, you created a 2-layer neural network from scratch and now have a better understanding of how neural networks work.

In this second part, you’ll use your network to make predictions, and also compare its performance to two standard libraries (scikit-learn and Keras).

This tutorial builds a login system for an Android app. The app allows the users to register using a username and a password. A local server implemented in Python using Flask accepts the user data and inserts them into a MySQL database.

For securing the password, it’s encrypted using the MD5 hashing algorithm. After successful registration, the user will be able to log into the system by entering a server-verified username and password.
