K-Nearest Neighbors (KNN) is a supervised learning algorithm used for both regression and classification. Its operation can be compared to the following analogy:

To make a prediction, the KNN algorithm doesn’t calculate a predictive model from a training dataset like in logistic or linear regression. Indeed, KNN doesn’t need to build a predictive model. Thus, for KNN, there is no actual learning phase. That’s why it’s usually categorized as a lazy learning method.

Pandas is an open-source Python library built on top of NumPy. Pandas is probably the most popular library for data analysis in Python. It allows you to do fast analysis as well as data cleaning and preparation. One amazing aspect of Pandas is the fact that it can work well with data from a wide variety of sources such as: Excel sheets, CSV files, SQL files, or even a webpage.

Due to the popularity of deep neural networks, many recent hardware platforms have special features that target deep neural network processing. The Intel Knights Mill CPU will feature special vector instructions for deep learning. The Nvidia PASCAL GP100 GPU features 16-b floating-point (FP16) arithmetic support to perform two FP16 operations on a single-precision core for faster deep learning computation.

It’s becoming increasingly easy to incorporate machine learning into your mobile app development toolkit, courtesy of platforms and dev tools such as Firebase’s ML Kit.

These tools conceal technical complexities by packaging pre-trained machine learning models for use. They also allow you to train and import your own models.

This tutorial is the 10th part in the series, ML Kit for Mobile Developers. If you’re not quite caught up, you can start here:

ML Kit’s Face detection API is one of the APIs that I left out from the ML Kit series (until now), mainly because I couldn’t find a proper use-case of this API.

When used in the right situation, neural networks can be an awesome solution to your learning problem. Neural networks allow you to feed in structured data (numerical and categorical data), wait for some magic to happen (note: not actual magic — it’s just maths), and out pops your answer — for example, maybe you’re trying to predict the result of an election from data from news sources. Convolutional neural networks allow you to do something similar but for images — for example, maybe you’re trying to predict whether an image is a hotdog or a not-hotdog.

Instagram is one of the leading social media platforms in the world with over a billion monthly users. It’s great for sharing pictures, connecting with friends and family, getting updates about our favorite celebrities, and posting stories using AR camera filters.

Google introduced a new product in the Firebase Suite earlier this year, Firebase’s Machine Learning Kit. ML Kit brings Google’s machine learning expertise to both Android and iOS apps in a powerful way. In this post I will dive into how we can make use of it in order to build a real-time face detector for an Android app.

Welcome back to part 5 of our series exploring how to build a side-scroller mobile game with Unreal Engine 4. If you haven’t yet read part 4, I’d recommend reading it here:

In the last part, we integrated our winning and losing mechanisms. Here, we’ll work on creating a boss enemy to make our game a bit more challenging.
