A Brief Look at Principal Component Analysis

By the time you being learning about Principle Component Analysis (PCA) you will have had some practice organizing data and, in particular, handling data in 2 dimension tables. For example, something you have likely already worked on a housing price predictor project where, among other things, you needed to find the price per square foot or the result of x dollars by y square feet. This value, however, was only one of many factors that went to into your price prediction. While this project may not have had many features, it likely still demonstrated how quickly things can become complicated…


These days machine learning seems to be on the tip of everyone’s tongue with just about everyone from new Youtubers to well-established businesses scrambling to get in on those sweet sweet insights. Many of these insights come as a direct result of painstakingly gathered data and well-developed models. Training these models is a crucial step in the process but figuring how to assess the model can be a challenge. This is where evaluation methods come in.

Model evaluation methods are exactly what they sound like. They are methods for evaluating the correctness of models on test data. These methods measure…


Like many people, math was far from my favorite subject in school. “When will I ever need this?” I thought. Cut to my adult life where I would end up needing it more than most due to its unmatched ability to provide evidence in all kinds of analysis. Still, I can’t help but still feel disdain for the subject. Unless, of course, the usefulness of the topic at hand is immediately evident. Bayes theorem is one such topic. Bayes theorem is more than just a mathematical equation, it’s a method for checking your instinctual assumptions. In a world where many…


If you had asked anyone in any part of the world and of any age and background what they thought would happen in 2020, I would bet you’d be hard-pressed to find anyone who saw it happening the way that it did. In many ways, it will be remembered as a nightmare of a year full of anxiety and heartache, but for me, it will also be remembered as the year we all got a reality check. Prior to this year, the idea of a global pandemic was something most people had only read about. Many of us learned the…
