A few days ago my eyes fell on a new release of Akka Stream Kafka. Since I’m doing a lot with Kafka currently and I really wanted to get my hands dirty with Akka this sounded very good. Also a good opportunity to see if an upgrade to Kafka 0.10.0.1 (from 0.8.2.2) is worth while (since older versions of Kafka are not supported in Akka Stream Kafka 0.11).
Finding the link between heart rate and running pace with Spark ML – Fitting a linear regression model
Besides crafting software I’m an avid runner and cyclist. Firstly for my health and secondly because of all the cool gadgets there are available. Recently I started with a Coursera course on Machine Learning and with that knowledge I combined the output of my running watch with Spark ML. In this article I discuss how to load gps and heart rate data to a linear regression model and ultimately get a formula with heart rate as input and running pace as output.
