Agile Software Development has gained traction in recent years, expanding its foundational values to many sectors outside of tech. For the uninitiated, the plethora of technical jargon can be very intimidating, and those seeking to enter a technical role need to at least have an understanding of an Agile environment. What is Agile? Purists will… Continue reading A Layman’s View of an Agile Environment
A Mathless Breakdown of the Random Forest Classification Algorithm
Review A previous post discussed how the decision tree algorithm classifies items using the gini impurity index--a simple score that is easily calculated. Please visit this post for some background information or a refresher if necessary. Pitfalls of Decision Trees Decision trees are relatively straightforward, regardless whether it is built on the gini impurity index… Continue reading A Mathless Breakdown of the Random Forest Classification Algorithm
Support Vector Machine: The Kernel Trick Explained with Minimal Math
Introduction Support vector machines are supervised learning algorithms that help classify things into different groups. Supposed that the shapes below had to be separated somewhere on the line. Where should the line be drawn? It could be drawn line this, which might allow for some misclassification: In this example, it's pretty intuitive that the dividing… Continue reading Support Vector Machine: The Kernel Trick Explained with Minimal Math
