The Stage Between Stages Today, the 31st of December 2020, is my last official day as an employee of Discovery. I met some wonderful people, and learned a great deal. I expanded my techical repertoire: I learned more about R, statistics, machine learning and data science/analysis in general. I was fortunate to also be part of something called the Leadership Lab: once a week a group of about 15-20 people from across the group sat down with a top exec and discussed articles broadly encompassing the topic of leadership.

In this blog post, we discuss what XGBoost is, and demonstrate a pipeline for working with XGBoost in R.

In this post we'll talk about what the Central Limit Theorem is, why it's important, and how we can see it in action, using R.

Hello Person From The Internet who has decided to come here. Thank you for dropping by.

Today I’m going to talk about a book I read - Work Rules!: Insights from Inside Google That Will Transform How You Live and Lead by Laszlo Bock.

In this post we discuss the H2O machine learning platform. We talk about what H2O is, and how to get started with it, using R - we create a Random Forest which we use to classify the Iris Dataset.

In this post we talk about the inverse matrix. We discuss what it means for a matrix to be invertible. We then discuss what it means for a matrix not to be invertible - singular. Finally, we briefly go through how to find a matrix’s inverse.

In this article we describe what the nullspace is. We go on to explain how to find the nullspace.
