Overview of this book

R provides excellent visualization features that are essential for exploring data before using it in automated learning. Applied Supervised Learning with R helps you cover the complete process of employing R to develop applications using supervised machine learning algorithms for your business needs. The book starts by helping you develop your analytical thinking to create a problem statement using business inputs and domain research. You will then learn different evaluation metrics that compare various algorithms, and later progress to using these metrics to select the best algorithm for your problem. After finalizing the algorithm you want to use, you will study the hyperparameter optimization technique to fine-tune your set of optimal parameters. The book demonstrates how you can add different regularization terms to avoid overfitting your model. By the end of this book, you will have gained the advanced skills you need for modeling a supervised machine learning algorithm that precisely fulfills your business needs.

Preface

Regression


Now that we have seen the machine learning workflow, we will take two widely used types of machine learning algorithms: regression and classification; both employ supervised learning to train the models. The entire theme of this book revolves around these two types of algorithms. The Beijing PM2.5 dataset will be used extensively in demonstrating both these types. The dataset will help in understanding how one can convert a regression problem into a classification problem and vice versa.

Simple and Multiple Linear Regression

Regression is one of the most useful and essential tools in analytics and econometrics (the branch of economics concerned with the use of mathematical methods, especially statistics, in describing economic systems). In many ways, modern machine learning has its roots in statistics, and one can attribute that mostly to Sir Francis Galton's work. Galton was an English Victorian-era statistician and polymath with deep interest and expertise in fields such as genetics...
