Tutorial: An Introduction to Apache Spark

Overview After lots of ground-breaking work led by the UC Berkeley AMP Lab, Apache Spark was developed to utilize distributed, in-memory data structures to improve data processing speeds over Hadoop for most workloads. In this post, we’re going to cover the architecture of Spark and basic transformations and actions using a real dataset. If you […]

Tutorial: K Nearest Neighbors in Python

In this post, we’ll be using the K-nearest neighbors algorithm to predict how many points NBA players scored in the 2013-2014 season. Along the way, we’ll learn about euclidean distance and figure out which NBA players are the most similar to Lebron James. If you want to follow along, you can grab the dataset in […]

Tutorial: K-Means Clustering US Senators

Clustering is a powerful way to split up datasets into groups based on similarity. A very popular clustering algorithm is K-means clustering. In K-means clustering, we divide data up into a fixed number of clusters while trying to ensure that the items in each cluster are as similar as possible. In this post, we’ll explore […]
