Android provides many ways of storing an application’s data. One of these ways is called SharedPreferences. SharedPreferences allow you to save and retrieve data in the form of a key-value pair. It’s beneficial to use SharedPreferences APIs only when you have a relatively small collection of key-values that you’d like to save. Each SharedPreferences file is managed by the framework and can be private or shared.

Solving equations using neural networks: Exploring Facebook AI’s latest research effort
Articles
Computer systems have always been man’s best friend when dealing with intensive, computation-heavy mathematical problems. From simple calculations on a calculator to large statistical operations in R, this technological frontier has made life easier for a lot of us.
However, even computers are known to fault when numbers turn into letters and algebra starts getting involved. One might hope that with the advent of increasingly sophisticated machine learning and AI algorithms, this could be solved—but hopes and dreams continued to remain hopes and dreams…until now.
Spam Filtering Using Bag-of-Words
Articles
In this post, we’re going to employ one simple natural language processing (NLP) algorithm known as bag-of-words to classify messages as ham or spam. Using bag of words and feature engineering related to NLP, we’ll get hands-on experience on a small dataset for SMS classification.
So, what are we waiting for?
Advancements in Artificial Intelligence in iOS 14
Articles
Apple has recently been pushing the envelope with regards to Artificial Intelligence, and WWDC 2020 was no different.
From machine and deep learning to computer vision and natural language processing, Apple’s introduced a slew of enhancements and improvements across their built-in frameworks that help mobile application developers build better AI-powered iOS apps.
PencilKit, a drawing framework that was introduced in iOS 13, was also powered with machine learning this year.

6 Takeaways from Snapchat’s Lens Fest
Articles
I’ve never quite attended an event like Lens Fest. Not just because it was entirely virtual, but largely because of the community of people it was celebrating — AR developers, graphic designers, 3D artists, software engineers, ML engineers, and a wide range of other people from around the world who, put simply, create really cool stuff. I was blown away by all the amazing experiences people from all walks of life are building with Lens Studio.
2019’s Top Open Source Machine Learning Projects
Articles
In this piece, we’ll look at some of the top open source machine learning projects in 2019, as ranked by MyBridge.
This project is an implementation of the SV2TTS paper with a vocoder that works in real-time. Using this repo, one is able to clone a voice in 5 seconds to generate arbitrary speech in real-time.

Working with Audio Data for Machine Learning in Python
Articles
Most of the attention, when it comes to machine learning or deep learning models, is given to computer vision or natural language sub-domain problems.
However, there’s an ever-increasing need to process audio data, with emerging advancements in technologies like Google Home and Alexa that extract information from voice signals. As such, working with audio data has become a new trend and area of study.

Working with the OpenCV Camera for Android: Rotating, Orienting, and Scaling
Articles
TLDR: OpenCV’s camera doesn’t handle a mobile device’s portrait mode well by default. Grab the code below and drop it into CameraBridgeViewBase to utilize the OpenCV rear and front facing Camera in full screen portrait orientation.

Even with all of the recent developments in Android’s ARCore, there are plenty of reasons you might need OpenCV in your mobile Augmented Reality project. With image processing, machine learning, object detection, optical flow, and numerous other features — the library does a lot, and it isn’t bound to just one platform, meaning that with minimal changes you can port your code to iOS, Unity, Python, and more.

Using the Camera & Gallery in Flutter Apps
Articles
In this third installment of our Flutter series, we’ll look at how you can use native device features. Specifically, the features we’ll look at are designed for working with a device’s camera and gallery.
By the end of this piece, you’ll be able to build an app that takes images via the camera or gallery and stores it on the device. We’ll also see how you can use the Provider package to store images in a way that enables you to send them to a backend server.
