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

Defining the Problem Statement


If you recollect the data we explored in Chapter 1, R for Advanced Analytics, bank marketing data, we have a dataset that captures the telemarketing campaigns conducted by a bank to attract customers.

A large multinational bank is designing a marketing campaign to achieve its growth target by enticing customers for bank deposits. The campaign has been ineffective in luring customers, and the marketing team wants to understand how the campaign can be improved to achieve the growth targets.

We can reframe the problem from the business stakeholders' perspective and try to see what kind of solution would best fit here.

Problem-Designing Artifacts

Just like there are several frameworks, templates, and artifacts for software engineering and other industrial projects, data science and business analytics projects can also be effectively represented using industry standard artifacts. Some popular choices are available from consulting giants such as McKinsey, BCG, and decision...
