One-Hot Encoding in Python with Pandas and Scikit-Learn
In computer science, data can be represented in a lot of different ways, and naturally, every single one of them has its advantages as well as disadvantages in certain fields.
Since computers are unable to process categorical data as these categories have no meaning for them, this information has to be prepared if we want a computer to be able to process it.
This action is called preprocessing. A big part of preprocessing is encoding - representing every single piece of data in a way that a computer can understand (the name literally means "convert to computer code").
In many branches of computer science, especially machine learning and digital circuit design, One-Hot Encoding is widely used.
In this article, we will explain what one-hot encoding is and implement it in Python using a few popular choices, Pandas and Scikit-Learn. We'll also compare it's effectiveness to other types of representation in computers, its strong points and weaknesses, as well as its applications.

The Weekly Challenge #054
For the first time, since I started participating the weekly challenges, I thought of doing one-liner. With handy CPAN modules, it was pretty straight forward in Perl. Even Raku with built-in features wasn’t far behind Perl. Like in the past, I learn something new in Raku every week. This week was no different. I will share what I learnt this time later.

How to compare objects in PHP
PHP offers a simple way to compare objects using the comparison (==) and identity (===) operators.
When using the comparison operator (==), object variables are compared in a simple manner: Two object instances are equal if they have the same attributes and values and are instances of the same class.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
