R: Unleash Machine Learning Techniques

Business case

In the upcoming case study, we will apply KNN and SVM to the same dataset. This will allow us to compare the R code and learning methods on the same problem, starting with KNN. We will also spend some time drilling down into the confusion matrix, comparing a number of statistics to evaluate model accuracy.

Business understanding

The data that we will examine was originally collected by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK). It consists of 532 observations and eight input features along with a binary outcome (Yes/No). The patients in this study were of Pima Indian descent from South Central Arizona.
