This post is a part of a series about feature engineering techniques for machine learning with python.
You can check out the rest of the articles below — links will be added as posts go live:
Welcome back! Part two in our series intends to give you an overview of the type variable, which you can find in a given dataset. It’s essential to know the different variables’ types to better to engineer them.

This article is a part of a series about feature selection techniques. You can check out the rest of the articles as they are/become available:
Welcome back! This post will give you an overview of wrapper methods for feature selection.
In the last post in the series, we explored the filter methods that tend to select features independently and work with (essentially) any machine learning algorithm. Consequently, one of the disadvantages of these methods is that they tend to ignore the effect of the selected feature subset on the performance of the algorithm.

Waymo has driven more than 20 million miles on public roads in over 25 cities. They also drove tens of billions of miles in simulations (as we’ll see later in the article). Additionally, Waymo is operating a taxi service in the United States, transporting passengers—for real—without a driver.
Given their growing presence in the real world, I want to dive deep into Waymo’s technology so you can understand what’s actually behind this giant.
In this tutorial, we’ll continue learning the various use-cases of the TensorFlow.js library. Our previous tutorial used this library for real-time human pose estimation. Here, we’re going to detect hand gestures using the library.
In this tutorial, we’re going to focus our pose algorithm on a smaller area—human hands. We are going to detect the hand poses and gestures using the TensorFlow.js library. Like in the previous tutorial, we are going to make use of a webcam for gesture detection and canvas for drawing or displaying the result of the detection.

Machine learning is a buzzword nowadays. There are plenty of theories going around, but it’s hard to see real applications that can be built by an indie developer.
Developing an end-to-end machine learning system requires a wide range of expertise in areas like linear algebra, vector calculus, statistics, and optimization.
Therefore, from a developer’s perspective, there’s a high learning curve that stands in the way, but the latest tools take care of most of the work for developers, leaving them free to code.

The power of React Native as a framework continues to increase over time. For those who are unfamiliar, React Native is a cross-platform framework developed by Facebook. It’s open source and lets you build mobile applications using JavaScript as its core.
Thanks to Nicolas Gallagher’s open source project React Native for Web, now you can use React Native API components to build a web application that uses React DOM as its core. React Native already makes it convenient to write mobile apps for two platforms: iOS and Android. And now the web is slowly entering the picture. 🤩
The deployment of a machine learning (ML) model to production starts with actually building the model, which can be done in several ways and with many tools.
The approach and tools used at the development stage are very important at ensuring the smooth integration of the basic units that make up the machine learning pipeline. If these are not put into consideration before starting a project, there’s a huge chance of you ending up with an ML system having low efficiency and high latency.

Hi there, this is the 3rd part of a 3 part series, for better understanding kindly read my first and second articles here:
In part 3, we’ll be taking the model we built in parts 1 and 2 and exploring how to implement it on a Raspberry Pi 3.
Raspberry Pi is a low-cost micro computer that can be plugged into a computer monitor or TV alongside a keyboard and mouse to simulate a full PC experience.

In certain cases, there are requirements where a certain page in your application can only be viewed in a particular orientation, i.e. portrait/landscape. Dealing with this issue in native Android/iOS is like a walk in the park, but doing this in a cross-platform framework can be confusing!
Want to find the easiest way out of it? This tutorial is intended to show you how to force an orientation on a single page while developing with Xamarin. Let’s get to it!

Machine learning as a field is full of technical terms, making it difficult for beginners to get started. One might see things like “deep learning,” “the kernel trick,” “regularization,” “overfitting,” “semi-supervised learning,” “cross-validation,” etc. But what in the world do they mean?
One of the core tasks in building any machine learning model is to evaluate its performance. It’s fundamental, and it’s also really hard.
