Posted on February 12, 2017

Let’s talk about making assumptions. Each time you form an opinion on something, you don’t re-examine each of the beliefs that contributed to that opinion. For example, when you order food at a restaurant, you pick the foods that you think will taste good. You don’t spend hours questioning the...

## An Introduction to Algebraic Groups for CS People

Posted on January 2, 2017

One of my favorite classes in college was Abstract Algebra. It was my first non-CS non-elementary math class, and I took it because I knew I didn’t want to graduate without having broadened my mathematical horizons beyond CS. As it turned out, Abstract Algebra felt pretty familiar. Many of the...

## Computation Theory Part 2 - Complexity Classes and NP Completeness

Posted on November 19, 2016

Welcome to part 2 of the Computation Theory series! In the last post, we discussed decidability and the halting problem. In this post we will talk about complexity classes. Time Complexity If you’re not used to reasoning about algorithms and their complexity, there is an enormous amount of great material...

## Computation Theory Part 1 - The Halting Problem

Posted on October 15, 2016

When you think about the most important fields of mathematics for a data scientist to know, you’ll almost certainly name calculus, probability/statistics, and linear algebra. These fields form the underpinnings of the most popular data analysis, signal processing and machine learning techniques. But in my experience, I’ve found that there...
