What algorithm should you use on your dataset? This is the most common question in applied machine learning. It’s a question that can only be answered by trial and error, or what I call: spot-checking algorithms. In this post you will discover how to spot check algorithms on a dataset using R. Including the selection of […]
You must understand your data to get the best results from machine learning algorithms. Data visualization is perhaps the fastest and most useful way to summarize and learn more about your data. In this post you will discover exactly how you can use data visualization to better understand or data for machine learning using R. […]
You must become intimate with your data. Any machine learning models that you build are only as good as the data that you provide them. The first step in understanding your data is to actually look at some raw values and calculate some basic statistics. In this post, you will discover how you can quickly get […]
As a developer you can pick-up R super fast. If you are already a developer, you don’t need to know much about a new language to be able to reading and understanding code snippets and writing your own small scripts and programs. In this post you will discover the basic syntax, data structures and control […]
