R: Unleash Machine Learning Techniques

An example of deep learning

Shifting gears away from the Space Shuttle, let's work through a practical example of deep learning, using the h2o package. We will do this on the data that we used for some of the chapters: the Pima Indian diabetes data. In Chapter 5, More Classification Techniques — K-Nearest Neighbors and Support Vector Machines, the best classifier was the sigmoid kernel, Support Vector Machine. We've already gone through the business and data understanding work in that chapter, so in this section, we will focus on how to load the data in the H20 platform and run the deep learning code.
